Tapped Density Tester – SVM

SVM Tapped Density Tester – Overview

The ERWEKA SVM tapped density tester has been designed to measure tapped volume and tapped density of powders, granules and similar products. It is available for holding one or two glass cylinders and works according USP method 1 (300 strokes/min; stroke height 14 mm) or USP method 2 (250 strokes/min; stroke height 3 mm), which is equal to Pharm.Eur. and DIN ISO EN 787/11 requirements. As a special version, the SVM 223 offers these two test methods simultaneously: one test station operates according to USP method 1 and the second test station according to USP method 2.

The ERWEKA SVM is now able with automatic calculation of tapped density, Hausner ration and compressibility index, with test results printed out as a report.

Compliant glass cylinders are available in 100 ml, 250 ml and 500 ml versions for the test stations.  A special version for higher volumes and weights is available on request.

A noise reducing chamber is also available for the SVM – click here to find out more.
