The
TD-1020 offers a simple and standard means of measuring the tapped
density of powders, granules, pellets, flakes and other bulk
substances. The TD-1020 is a two-station tap density tester supporting
both USP Method I and USP Method II as well as ASTM. To ensure a free
drop of the cylinder from the required height, the two stations are
provided with virtually friction-free bearings. Each station is
directly driven by independent motors to ensure a maintenance-free drive
and a simultaneous rotating and tapping motion minimizes any possible
separation of the mass during tapping down.
