Tablet Hardness Testers

The Stokes Tablet Hardness Tester Model 539 is an indispensable tool for tablet manufacturers, designed to accurately measure the hardness of tablets. This precision instrument addresses the common issue of variations in weight and thickness in tablets compacted from a single granulation. Such variations can affect tablet density and, consequently, their hardness. With the Model 539, users can directly measure the hardness of tablets in terms of the kilogram force required to crush them. This accurate measurement allows for the optimization of machine pressures, significantly reducing wear on punches and dies, and lowering overall tooling costs. By replacing subjective methods like finger sensitivity with this reliable, easy-to-use device, tablet makers can ensure consistent tablet quality while enhancing their production efficiency.
