Mercury Scientific Inc. Instruments

Flow property measurements generally fall into two main categories: dynamic analysis and static analysis. Dynamic instruments measure flow properties as the test material is moving or is about to move. Static instruments measure powder that is not moving and typically has been exposed to pressure. For a complete picture of a material's flow behavior, both types of testers are required. For solving specific flow problems, usually one type of tester or test is required.

We offer several varieties of powder testers to make sure you get the instrument you need for your application.


REVOLUTION Powder Analyzer (RPA)

Dynamic Analysis

Analysis of powders in a flowing or about to flow state





EVOLUTION Powder Tester (EPT)

Static Analysis

Fast and easy analysis of powder flow under pressure to simulate behavior in storage containers like silos, totes, bags and drums





Volution Powder Flow Tester (VFT)

Static Analysis

Traditional Shear Cell Analysis of the flow properties of powders and granular materials
