Dissolution Apparatus and Disintegration Tester
Tablet Hardness Tester
Quality Control Tests for Tablets
This test measures the amount of time required for a given percentage of the drug substance in a tablet to go into solution under a specified set of conditions. It is intended to provide a step toward the evaluation of the physiological availability of the drug substances.
In vitro dissolution test is performed using a variety of equipment/apparatus. The British Pharmacopoeia recommends three types of apparatus – the rotating basket, the rotating paddle, and the flow-through cell. The static-basket magnetic stirrer assembly can also be used for this test.
The rotating paddle method is generally more discriminatory than the basket method. The flow-through cell method is very useful, particularly for
1. Poorly soluble active constituents (can use large volume to achieve sink conditions)
2. Enteric-coated products (can easily change between different pH fluids)
3. Modified release products.
The dissolution medium for each drug is available in the individual drug monograph. For basic drugs, acidic media are used (e.g., 0.1 M hydrochloric acid) while alkaline media are used for acidic drugs (e.g., alkaline buffers). For drugs with non-ionizing molecules, water is recommended.
The dissolution rate test is performed at 37 ± 1oC. Samples are removed from the dissolution chamber at periodic intervals and analyzed for drug content using a spectrophotometer. Dissolution samples removed for assay should be filtered to remove particles of drugs present, and to exclude tablet excipients that might otherwise interfere with the assay. Non-absorbent filter papers are recommended.
Most commonly, the results of dissolution tests are expressed in terms of the time required to release some percentage of the labeled amount of drug from the dosage form. This approach is reported to be particularly useful for quality control purposes once the dissolution characteristics of a drug and dosage form are well understood. For tablet dosage form design purposes, and for critical product comparison, however, the time required for substantially complete 80 to 90% release or amount released versus time profiles is the most desired approach.
While in vitro dissolution experiments may not correlate perfectly with in vivo bioavailability, the concept of dissolution efficiency proposed by Kahn and Rhodes could be employed to assess the most probable in vivo performance of a tablet formulation. The dissolution test is not designed to measure the efficacy or safety of the tablet being tested. Both the effectiveness and safety of a specific dosage form must be demonstrated, initially, by means of appropriate in vivo studies and clinical evaluation.
1. Physiochemical properties of the drug:
a. Polymorphic form: A metastable form of a solid has higher solubility and dissolution compared to its stable counterpart.
b. Particle size: The smaller the particle size of a solid, the larger the particle surface area and the higher the dissolution.
c. Salt form: A salt form of a drug has a higher aqueous solubility compared to its conjugate acid or base, as well as higher dissolution.
d. Hydrates versus anhydrates: The anhydrous form shows higher dissolution than hydrates due to their solubility differences.
2. Factors related to tablet manufacturing:
a. The amount and type of binder can affect the hardness, disintegration, and dissolution of tablets.
b. The method of granulation, granule size, and size distribution can affect tablet dissolution.
c. The concentration and type of disintegrants used, as well as the method of their addiction, can affect disintegration and dissolution.
d. Compression load can influence the density, porosity, hardness, disintegration, and dissolution of tablets.
3. Factors related to the method of dissolution study:
Composition of the dissolution medium, pH, ionic strength, and viscosity.
Type of dissolution equipment.
Temperature of the medium.
Volume of dissolution medium.
Intensity of agitation.
Sink or nonsink conditions (under a sink condition, the concentration of the drug should not exceed 10 – 15 % of its maximum solubility in the dissolution medium in use). Sensitivity of analytical method used to determine drug concentration in the release medium.

These are tests that are performed on tablets and which are not listed in official compendia and concern a variety of quality attributes that need to be evaluated, such as the porosity of tablets, hardness or crushing strength test, friability test, tensile strength determination, thickness test, etc.
Some of these tests have no officially set limits for acceptance or rejection and thus may vary from manufacturer to manufacturer and from formulation to formulation.
Crushing strength and friability appeared in the 2001 Edition of British Pharmacopoeia (Appendix A324). There was however no definite set limits. The two tests are, therefore, here considered under non-pharmacopoeial tests.
Tablet Hardness or Crushing Strength Test
This measures the degree of force (in kilograms, pounds, or in arbitrary units) needed to fracture a tablet. Besides the concentration of binders used and the compression force, the hardness of a tablet depends on
i. The characteristics of the granules to be compressed e.g., hardness and deformation under load.
ii. The type and concentration of lubricant used and
iii. The space between the upper and lower punches at the time of compression.
The crushing strength of tablets is usually checked using Monsanto or Stokes hardness tester, Strong-Cobb hardness tester, and the Pfizer crushing strength tester. All are manually used. So, the strain rate depends on the operator.
Currently, electrically driven hardness testers such as those manufactured by SOTAX, Key, Van Kel, Erweka, Dr. Schleuniger Pharmatron, etc., are widely used to measure the crushing strength of tablets.
This equipment eliminates the operator variability encountered with manual hardness testers. Newer equipment with printers is also available.
A force of about 4 kg is considered the minimum requirement for a satisfactory tablet. Measurement is usually carried out using a minimum of ten tablets.
It has been found that a linear relationship exists between crushing strength and the logarithm of compressional force, except at high forces.
The strength of a cylindrical flat-faced tablet can be expressed as tensile strength (Ts). This can be calculated as follows:
Where F is the force needed to fracture a cylindrical flat-faced tablet of thickness t along its diameter D.
This measures the resistance of tablets or granules to abrasion or fracture. The idea behind this test is to mimic the kind of forces, caused by phenomena such as collisions and sliding of tablets towards each other, which a tablet is subjected to during coating, packaging, handling, and shipping.
A minimum of 20 tablets are dedusted, weighed, and subjected to a uniform tumbling motion for a specified time. They are then deducted and reweighed.
The measure of abrasion/ friability loss is usually expressed as a percentage loss in weight. It is calculated from the equation:
The test is rejected if any tablet caps, laminates or breaks up in course of the test. As a rule of thumb, a maximum weight loss of not more than 1% generally is considered acceptable for most pharmaceutical products.
Values of up to 2% or above have been reported in direct compression formulations. The friability of tablets may be influenced by moisture content. Chewable tablets show a high friability weight loss compared to conventional compressed tablets.
A number of instruments are available for friability tests but the most popular and most reliable is the Roche Friabilator.
Tablet thickness is determined by the diameter of the die, the amount of fill permitted to enter the die cavity, the compaction characteristics of the fill material, and the force or pressure applied during compression. To manufacture tablets of uniform thickness during and between batch productions for the same formulation, care must be exercised to employ the same factors of fill, die, and pressure.
The degree of pressure affects not only the thickness but also the hardness of the tablet; hardness is perhaps the more important criterion since it can affect disintegration and dissolution. Thus, for tablets of uniform thickness and hardness, it is doubly important to control pressure. Tablet thickness also becomes an important characteristic in packing operations and in counting tablets using filling equipment which uses the uniform thickness of the tablets as a counting mechanism.

Tablet thickness is measured with a vernier caliper, thickness gauge or automated equipment (Automatic weight, hardness, thickness, and tablet diameter test instrument). The thickness of a tablet should be controlled within ±5% variation of a standard value depending on the size of the tablet. Other non-pharmacopoeial tests include measurement of tablet diameter, porosity, liquid penetration, mechanical strength, and density.

The basic components of an optical microscope consist of optics, a stage to support the specimen, and a source of light; however, these features can be very simple to highly complex, depending on your needs and budget. A state-of-the-art design can feature multiple illuminators, polarizers, DIC and phase contrast options, fluorescence attachments, automatic exposure control, and zoom capabilities.
Since the objectives determine the image quality that the microscope can produce, it makes sense to start with the one that will eliminate most optical aberrations. Types include plan achromat, semi-apochromatic, and apochromatic, as well as water and oil objectives.
Depending on your application, additional features to look for may include high numeric apertures, long working distances, objectives that permit multimode imaging, digital and advanced motorization capabilities, and updated illumination systems.
Specifications: available in various designs, including Digital models.
Applications of laboratory microscopes:
The goal of any laboratory microscope is to produce clear, high-quality images, whether an optical microscope, which uses light to generate the image, a scanning or transmission electron microscope (using electrons), or a scanning probe microscope (using a probe). Upright microscopes are the most common type, with the lighting system below the stage and the lens system above; inverted microscopes, particularly useful for cell culture, reverse this configuration. Applications include biotechnology, pharmaceutical research, nanophysics, microelectronics, and geology.
Commonly used compound microscopes are usually binocular (two eyepieces) and use multiple lenses to produce a 2-D image. They can achieve a maximum of about 1500X magnification and are popular for use in biology and in forensic labs. Stereo microscopes offer 3-D viewing at lower magnification and are available in fixed and zoom variations. Digital microscopes eliminate eyepieces, combining optics with a CCD camera to view images on a computer screen.
Techniques range from simple brightfield to darkfield, phase contrast, differential interference contrast, confocal (useful for thick specimens), and fluorescence microscopy, which continues to prove its value in areas such as cell biology, genetics, and embryology. The use of polarized light in polarizing microscopes results in increased image contrast.
A centrifuge is a laboratory device that is used for the separation of fluids, gas, or liquid, based on density. Separation is achieved by spinning a vessel containing material at high speed; the centrifugal force pushes heavier materials to the outside of the vessel. This apparatus is found in most laboratories from academic to clinical to research and is used to purify cells, subcellular organelles, viruses, proteins, and nucleic acids. There are multiple types of centrifuge, which can be classified by the intended use or by rotor design. From the large floor variety to the micro-centrifuge, there are many varieties available for the researcher.
Benchtop Centrifuges are a broad class of centrifuges characterized by their small bench space footprint. Depending on the research need, a variety of different aspects can be considered. Maximum speed in RCFs can range from as low as a few hundred to over 50,000 x g. Tube volumes can range from under 1 mL (such as with PCR tubes) to a few liters. Different types of rotors such as fixed angle, swinging bucket, and continuous flow are also typically interchangeable. Check out our diverse listings of benchtop centrifuges.
Refrigerated Benchtop Centrifuges are compact instruments ideal for the centrifugation of samples that may be temperature sensitive, such as live cells, animals, or proteins. Many feature interchangeable rotors and adaptors to accommodate a wide range of sample volumes from under 1 mL to a few liters. Speeds can also vary, and some models can reach up to 60,000 x g. Check out the different refrigerated benchtop centrifuges currently on the market.
Clinical Benchtop Centrifuges are compact, low-speed centrifuges ideal for the separation of whole blood components, such as serum, plasma, buffy coat, red blood cells, as well as other bodily fluids. Their speeds may range between around 200 rpm to 6,000 rpm. Most clinical centrifuges can accommodate common blood draw tubes, but be sure to check with each vendor for specific tube sizes or tube adaptors. Check out a variety of clinical benchtop centrifuges from different manufacturers.
Microcentrifuges are staple instruments in many research laboratories that generally accommodate small tube volumes such as 2 mL, 1.5 mL, 0.5 mL, and PCR tubes. Microcentrifuges for routine laboratory procedures typically spin at speeds up to 16,000 x g, while more specialized instruments can reach speeds up to 30,000 x g. In addition, manufacturers may also offer interchangeable rotors and tube adaptors. Compare a variety of different ambient temperature microcentrifuges and refrigerated microcentrifuges.
Vacuum Centrifuges / Concentrators can use a vacuum, centrifugal force, temperature, and/or gas to remove liquid solvent for the concentration or desiccation of samples. This instrument is ideal for the purification or preparation of samples such as nucleic acids, proteins, peptides, and other compounds for a variety of research applications. For the evaporation of solvents, vacuum centrifuges typically utilize built-in heating systems. Check out different vacuum centrifuges or concentrators here.
Specifications: all types in all required models are available.
Digital Ultrasonic cleaning is based on the cavitation effect caused by high-frequency ultrasonic wave vibration signal in the fluid. Microscopic bubbles are formed, and they implode violently causing cavitation which creates an intense scrubbing action on the surface of the item being cleaned. The bubbles are small enough to penetrate microscopic crevices, cleaning them thoroughly and consistently.
Ultrasonic cleaning is extremely effective at removing dirt and grime which would normally require tedious manual cleaning by hand. It has been used to clean a wide variety of instruments and mechanical parts such as carburetors, returning them to almost "like new" conditions without damage to delicate parts.

Drying ovens are two types, general-purpose hot air oven and another is forced convection ovens.
Laboratory ovens are commonly found in clinical, forensic, and research laboratories. The basic function of ovens in the laboratory is to provide a uniform temperature. Based on the specific needs of the laboratory, different kinds of ovens are used including gravity, mechanical, conventional, and vacuum ovens. In biological laboratories, conventional hot air ovens are used for drying glassware and other equipment, pre-heating, and for sample incubation at higher temperatures. In case laboratories require airflow within the oven, the forced convection type can be used. Ovens are also used for drying samples, in which case, a vacuum pump oven is best suited. In forensic biology labs, such ovens are also sued to develop fingerprints. In biological laboratories, sterile conditions must be maintained even inside these ovens and hence, microbial filters may be used to filter the air entering and leaving the oven. The ovens are cleaned regularly too.
Specifications: available in various sizes and heating.
Hotplates & Magnetic Stirrers
A hotplate is a basic device that can be found in any lab and is primarily designed for heating liquid media. In many cases, it is combined with a magnetic stirrer for uniform temperature and good homogeneity of the liquid. Uses of Lab Hot Plates Magnetic stirrers without stirrers are used for a wide range of laboratory and industrial uses: heating liquids, utensils, parts, slides and more. The correct choice of laboratory hot plate depends on the user's requirements: Maximum required working temperature, Plate size required, Required temperature control, What is the use, what are the materials, the parts that heat, The required temperature uniformity.
For working temperatures up to 300-400 Celsius, use plates made of aluminum. They have excellent thermal conductivity. The larger they are, the better the temperature uniformity in them. Temperature uniformity improves as you get closer to the center of the plate because the edges of the plate have heat leakage.
The temperature of aluminum hot plates is limited to 370 degrees Celsius, above 400 degrees Celsius the aluminum begins to deform. For working temperatures up to 400-500 degrees Celsius, use plates made of iron or plates made of ceramic glass.
The processing of iron plates is less smooth than that of ceramic glass plates. Ceramic glass is resistant to chemicals but can break as a result of mechanical blows. For working temperatures up to 600 Celsius work with titanium plates.
The larger the hot plate, the larger the work area and the higher the power consumption.
The size of the small plates: 115 * 115 mm, 175 * 175 mm
The size of the medium-hot plates: 250 * 250 mm, 250 * 500 mm, 300 * 300 mm, 115 * 600 mm
And the size of the giant heating plates for the lab: 400 * 600 mm, 600 * 600 mm.
The huge plates have high power consumption and require a three-phase power supply. The plates can be ordered with separate temperature control. And plates with custom dimensions can be produced on demand.
Temperature controlling different aspects:
Digital temperature control will allow precise temperature control of a single degree, the option to set a heating rate, the option for a timer, option for computer communication.
An analog thermostat when temperature accuracy is not important.
External temperature tracker: There is a difference between the temperature of the plates and the temperature of the media or the part that rests on the plates. Because the temperature sensor is inside the plates and measures the temperature of the plates, the temperature of the liquid or part placed on it is lower than the temperature of the plates.
Safety controller for overheating protection - Another independent control circuit that will switch off the heating in the event of a fault in the main control circuit. Add safety controller in long processes at nights and weekends when plate works unattended.
Special Temperature programmer -Determining a temperature profile -Program or multiple programs with several segments of different temperatures.
The temperature uniformity of the plate can be checked with a temperature meter and a surface tracker A surface tracker makes good contact with the measured area because it is thin, wide, and springy and allows the user to check the temperature at different points of the plate to find out its temperature uniformity. As you move away from the edges of the hot plate towards the inside of the hot plate, the temperature uniformity improves. If you want to check the temperature uniformity over time at several points on the hot plate, use a data logger of several measurement channels.
Special Hot Plates for the Laboratory
If working with aggressive chemicals and depending on the use made of the plate, the plate can be coated with Teflon or anodized. Copper Hot plates can be produced, Lab Hot plates can be produced with water cooling or cooling of liquid nitrogen.
Precautions When Working with a Hotplate
Keep away from flammable materials - because the braces are exposed, the workers should be warned, and it is even advisable to hang a careful sign. It is advisable to work with gloves designed to work in the heat and with forceps.

Magnetic Stirrer Working Principle and Uses
Agitation and stirring processes are used in all chemical and biological laboratories in various shapes and sizes. Irrespective of the specific application or process that is being performed, the researchers or technicians need to use the best laboratory equipment for the job to make sure the results are consistent. The wrong agitation process leads to inaccurate results; that's why it is very much crucial to understand agitation options as per the application. For the agitation, various options are available. Among them, magnetic stirrer hot plates, and overhead stirrers are widely used.
What is a magnetic stirrer?
Magnetic stirrers use a rotating magnetic field to move a stir bar around in liquid samples, and some are coupled with stirring hot plate. The movement of this stir bar mixes the samples thoroughly with rapid movement and agitation. The user controls the magnetic field's speed, so it can be customized to the specific sample that's being stirred. These stirrers should be used with glass or other non-metal beakers to prevent interference with the magnetic field.
How does it work?
A stir bar magnet is placed inside a container, immersed in the fluid. A separate magnet is placed underneath the container so that it attracts the stir bar magnet. The lower magnet is usually attached to a motor that spins it. If the magnets are close enough, the stir bar magnet spins inside the container. Depending on the application, you can configure your magnetic stirrer with hot plates to heat your samples as they are stirred. With the use of a hot plate stirrer, you can mix a wide variety of samples for different applications.
Magnetic Stirrers vs Overhead Stirrers
Aside from magnetic stirrers, the samples can be mixed using motor power overhead stirrers. The overhead stirrers can handle larger volumes of liquid samples and/or high viscous liquids. Magnetic stirrers, on the other hand, can mix samples in a sealed container and samples can be heated more evenly by magnetic stirrer hot plates.
Types of Magnetic Stirrers
The magnetic stirrers are classified according to the size, configuration and applications. The digital hotplate stirrers are available to monitor the temperature and rotations per minute (RPM) accurately. The best magnetic stirrer hot plate should be able to mix the viscus solutions efficiently and should not uncouple the bar from drive magnet.
Magnetic Mini Stirrer
The laboratory magnetic stirrers are compact and occupy less space in the laboratory, consist of electronic controls that allow the user to regulate the speed with greater precision. It is resistive to hazardous and corrosive chemicals in the lab. The speed regulator in the stirrer controls the RPM.
Magnetic Stirrer with Timer
Magnetic stirrer with timer helps to automatically shut off the motor after the specific period. An in-built timer will off the stirrer once the pre-selected period has completed.
Heavy-Duty Magnetic Stirrers
The heavy-duty magnetic stirrers come with high mixing capacity. They also have good chemical resistance and are highly durable. They can be the best choice instrument for the laboratory to achieve accurate results. Heating magnetic stirrers are essential for most of the chemical reactions.
Battery Powered Magnetic Stirrer
They can be used where there is no electricity supply or other sensitive areas. They work with batteries and are mostly used in incubators and consist of rubber feet for stabilization.
Air Operated Turbine Magnetic Stirrer
Air operated turbine magnetic stirrer is a perfect instrument for mixing liquid up to 1 liter of solution. It uses a low-pressure air supply to power this magnetic stirrer. The critical aspect of this magnetic stirrer is that it eradicates the sparking hazard from electrical sources.
Uses of Magnetic Stirrers
The primary use of magnetic stirrer or hot plate with magnetic stirrer is to conduct biological and chemical experiments by mixing two components. It is equally suitable for solids or liquid samples to obtain a consistent liquid mixture. Examples include media for bacterial growth and chemical synthesis.

V-65 Vacuum Oven 65L Capacity
A vacuum Oven is used for vacuum drying, which is a mass transfer operation in which the moisture present in a substance, usually a wet solid, is removed by means of creating a vacuum. In chemical processing industries like food processing, pharmacology, agriculture, and textiles, drying is an essential operation to remove moisture. Vacuum drying is generally used for the drying of substances that are hygroscopic and heat sensitive. It is based on the principle of creating a vacuum to decrease the chamber pressure below the vapor pressure of the solvent, causing it to boil. With the help of vacuum pumps, the pressure is reduced around the substance to be dried. This decreases the boiling point of the solvent inside that product and thereby increases the rate of evaporation significantly. The result is a significantly increased drying rate of the product. The vacuum drying process is a batch operation performed at reduced pressures and lower relative humidity compared to ambient pressure, enabling faster drying.
Aditya Scientific's vacuum oven has achieved reduced power consumption through improved airtightness and insulation by using superior insulation materials and by changing both the door-locking mechanism and the enclosure construction. Airtightness and insulation capacity has a significant impact not only on temperature control but also on pressure control. In addition, the enhanced airtightness helps prevent a temperature rise in the surrounding area of the chamber.

BALL Mills and Grinding Mills
PM 100 planetary ball mill
What Is a Ball Mill?
When most people think of milling machines, they envision a vertically oriented machine that contains rotary cutters. Traditional milling machines such as this are used extensively in the manufacturing industry to reshape workpieces. However, there are many other types of milling machines, one of which is a ball mill. What is a ball mill exactly, and how does it differ from traditional milling machines?
Overview of Ball MillsAs shown in the adjacent image, a ball mill is a type of grinding machine that uses balls to grind and remove material. It consists of a hollow compartment that rotates along a horizontal or vertical axis. It’s called a “ball mill” because it’s literally filled with balls. Materials are added to the ball mill, at which point the balls knock around inside the mill.
How a Ball Mill WorksBall mills work by using balls to grind materials. Materials such as iron ore, paint, and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball mill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, less-coarse medium.
For a ball mill to work, critical speed must be achieved. Critical speed refers to the speed at which the enclosed balls begin to rotate along the inner walls of the ball mill. If a ball mill fails to reach critical speed, the balls will remain stationary at the bottom where they have little or no impact on the material.
Ball Mills vs Traditional Milling MachinesBall mills differ from traditional milling machines in several ways. First, ball mills don’t have a cutting tool. While traditional milling machines rely on a rotary cutting tool, ball mills leverage the force of moving balls to perform their operation. As a result, they don’t need a cutting tool.
Another difference between ball mills and traditional milling machines lies in their respective function. Both ball mills and traditional milling machines are designed to remove material. However, traditional milling machines support large workpieces, whereas ball bills support materials like ore, ceramics and paint. The material is added to the ball mill’s compartment, at which point it’s exposed to the rotating balls. This forceful rotation grinds down the material into a finer, powder-like medium.
PM 100 planetary ball mill
Produces constant high speed for high final fineness
Grinding jars from 12 to 500 mL
The PM 100 planetary ball mill is a benchtop unit designed to pulverize soft, fibrous, and brittle materials. The mill develops extremely high centrifugal forces resulting in energy input that is up to 50% higher than in other planetary ball mills. It has a single grinding station for grinding jars with a nominal volume of 12 to 500 mL and can achieve a final fineness of <1 µm. The unit can store up to 10 combinations of speed, grinding time, and interval settings for use with repetitive grinding tasks. All relevant data can be entered or called up via the multi-language graphic menu interface with a one-button operation.
The PM 100's offers automatic grinding chamber ventilation for grinding with solvents. Extraction fan exchanges air at a per-hour rate of more than 20 times the chamber volume. The single-station mill features a counterweight that can be adjusted on an inclined guide rail. The counterweight allows for compensation when using the different size grinding jars with differing centers of gravity and avoiding oscillations of the machine. PM 100 can accommodate two stacked grinding jars. The "comfort" range of grinding jars has been designed for extreme working conditions such as long-term trials, wet grinding, high mechanical loads, and maximum speeds as well as for mechanical alloying.
