Mercury Scientific has announced the addition of a static powder flow tester, Evolution Powder Tester, to its existing powder-testing product line.
This new Evolution Powder Tester (EPT) is an economical 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 Evolution Powder Tester (EPT) offers many advantages over traditional shear and other uniaxial testers.
The EPT is a standalone instrument designed just 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 for any laboratory or manufacturing environment.
In addition, it takes approximately 3min for a user to test one sample.
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 are difficult with traditional shear testers and uniaxial testers.
The analysis cells for many these instruments are very expensive and do not include the means of applying pressure for significant periods of time.
Mercury Scientific also offers the Revolution Powder Analyzer 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 now offers both instruments with their accessories together as a package at a discounted price.
