Mercury Scientific has extended its powder testing product line with the addition of the Evolution static powder flow tester.

The Evolution powder tester (EPT) is described as an economical and easy-to-use powder flow tester that measures the unconfined yield strength of a material (a critical flow property) at pressures up to 500KPa.

The unconfined yield strength can be measured at one pressure or at many different pressures in order to create a flow function.

The flow function presents the material’s gain in strength as more pressure is applied to it.

The EPT is claimed to offer many advantages over traditional shear and other uniaxial testers.

It is a standalone instrument designed for powder testing and is not an accessory to a general-purpose instrument.

This allows the design to be cost-effective, easy to operate and suitable to any laboratory or manufacturing environment.

In addition, it takes approximately three minutes for a user to test one sample.

This is less testing time than other shear or uniaxial testers, according to Mercury Scientific.

With the EPT, time consolidation tests can be performed with sample cells and weights that allow a material to be subjected to various pressures over long periods of time.

The EPT time cells are designed so that they can be easily placed in ovens or humidity chambers to study their effects on materials in storage situations.

Studying the effects of humidity and pressure over long periods of time is difficult with traditional shear testers and uniaxial testers.

The analysis cells for many of these instruments are expensive and do not include the means of applying pressure for significant periods of time.

Mercury Scientific also offers the Revolution powder analyser for dynamic powder flow testing.

With both instruments, customers are able to study the effects of all different processes and environmental conditions on their materials during handling, transportation and storage.

Mercury Scientific offers both instruments with their accessories as a package at a discounted price.
