AUTOTAP Bulk Density Analyzer

The apparent bulk densities of powdered, granular of flaked materials are highly dependent on the manner in which the particles are packed together due to cohesion and shape effects. Tap density measurement is formalized in a number of international standards to which both Autotap models conform. To measure tap density, samples are placed in standard graduated cylinders and mounted on a universal tap platform designed to accommodate cylinders from 10mL to 500mL. After noting the initial volume and weight of the material, the number of desired taps is entered and tapping started. When the specified number of taps is completed, tapping stops automatically. Reading of the powder surface is facilitated by automatic rotation of cylinders during tapping which promotes a flat powder interface.
