Tablet Hardness Tester

Digital Hardness Tester for Tablet

UHT Series Tablet Hardness Tester series are the requisite instrument in detecting the hardness of tablets. All of our lab instruments are designed and manufactured in according to USP Specifications.

The Tablet hardness tester is used in the pharmaceutical industry to test the breaking point or "Tablet Break Force"; which is the force required to cause them to fail, and structural integrity of a tablet. This is an important test for the pharmaceutical industry as it ensures that tablets must be hard enough to withstand the stress of various conditions such as normal storage, transportation, and handling by the consumer before usage.



Tablet Hardness Tester Procedure

Tablet strength serves both as a criterion by which to guide product development and as a quality control specification. The tablet is placed between the platens so that compression occurs across a diameter. However, tablets with a unique or complex shape may have no obvious orientation for breaking force determination. Because the breaking force may depend on the tablet's orientation in the tester, to ensure comparability of results, it is best to settle on a standard orientation, preferably one that is most readily and easily reproduced by operators. In general, tablets are tested either across the diameter or parallel to the longest axis. Scored tablets have two orientation possibilities. When they are oriented with their scores perpendicular to the platen faces, the likelihood that tensile failure will occur along the scored line increases. .

Details on approved test methods and official monographs can be found in the European or US Pharmacopoeias.
