UHT Series Tablet Hardness Testers are the requisite instrument in detecting the hardness of tablets. All of our lab instruments are designed and manufactured in accordance with USP specifications.
The Tablet hardness tester is used in the pharmaceutical industry to test the structural integrity of a tablet (breaking point or "Tablet Break Force”, which is the force required to cause them to fail). 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 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.
