powder flowability
for the pharmaceutical industry


On the GT a special balance, which can measure stable weight while the sample is falling onto it, is integrated into the unit to determine the flow time of a sample weight or pre-specified sample volume, as well as sample weight, which falls within a specified flow time. For easy comparison a graph according to List and Müller (mass/time) is calculated and displayed and/or printed. Determination of the flow time of a pre-set sample weight (DAB 10) Determination of the flow time of a pre-defined sample volume Determination of the weight which flows in a pre-defined time Plot of flow time against sample weight in the form of a graph The GT is handled by alpha-numeric membrane keypad, results are shown at the illuminated 320 digit 16-line full-graphic LC display. As standard the unit is delivered with a stainless steel hopper (480 ml) and three stainless steel outlet nozzles (10; 15; 25 mm) which can be exchanged by a quick coupling. Additional stainless steel hoppers (100; 200 ml) and outlet nozzles (6; 8; 11,3 mm) are available as option. The GT comes with serial RS 232 and USB interface for transfer and print-out of results. GTB The GTB offers in addition to the standard flow properties the measurement of the angle of repose according to Pfrengle: the powder or granulate falls onto a plate with a specified surface and creates a cone. An integrated driven laser measures the side wall of the built-up cone and the actual angle is calculated and displayed and/or printed.
