Tablet Hardness Tester

Other Products

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.

Design Features

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
Requiring only a modest investment, the standard unit is designed to test tablets ranging in size from the smallest tablet size to ¾” diameter with a maximum thickness of 1/3”. The simplified design of the Stokes Tablet Hardness Tester Model 539 provides for quick and accurate reading, and can be equipped with special parts to permit the testing of larger diameter tablets at higher pressures.

Optional Accessories

The Stokes Tablet Hardness Tester can be equipped with special parts to permit the testing of larger diameter tablets, at higher pressures. These parts consist of the following:

  • Modified Head (or anvil): Will accommodate a full 7/8 inch diameter spherical tablet, or up to 1 3/16 inch diameter flat-face or convex tablet.
  • Modified Duty Spring: Is capable of exerting a pressure of 60 kilograms—three times greater than the standard spring, which is rated at 20 kilograms.
