ABSTRACT:
An improved tablet hardness tester includes a ram and anvil for fracturing a tablet therebetween, a support for holding a tablet in position for fracturing between the ram and anvil, a strain gauge for measuring the force exerted by the ram in fracturing the tablet, and an indicator for indicating the measured force. The support according to the invention is a plurality of spaced-apart elongated member, preferably a pair of parallel wires. A tablet is placed on these wires and then crushed by the ram and anvil so that the pieces of the broken tablet fall beneath the wires into a container, thus eliminating the need for cleaning the support prior to a subsequent tablet hardness measurement.
