Tablets compacted on any tablet press from a single granulation may vary in weight and/or thickness. A variation in either will result in a change of density, which affects tablet hardness. By determining the actual tablet hardness required, machine pressures can be reduced, resulting in less punch and die wear, and lower tooling costs
With this convenient easy-to-use instrument the Stokes Tablet Hardness Tester Model 539, tablet makers no longer need to rely on finger sensitivity or other “guesswork” methods, they can measure tablet hardness directly in terms of kilograms of pressure require to crush the tablet. This reading is then correlated with the following:
Method of manufacture
Desired physical characteristics of the tablet
Composition
