Freeman Technology launches stand-alone uniaxial tester

Freeman Technology has launched the Uniaxial Powder Tester (UPT), its first stand-alone uniaxial tester for simple, sensitive and cost-efficient powder characterisation. The product was developed in collaboration with the University of Edinburgh and, as a major industrial powder processor, delivers automated, repeatable measurement and provides a cost-effective alternative to traditional powder testing techniques.

“Uniaxial powder testing is a simple and intuitive method that measures an intrinsic property of a bulk solid,” said Tim Freeman, Managing Director of Freeman Technology. “The UPT draws on our in-depth understanding of powders and the precision engineering that underpins the worldwide success of the FT4 Powder Rheometer®. The result is a completely new, repeatable, versatile, low cost and robust powder tester for process development, trouble shooting and QC.”

The new instrument measures unconfined yield strength, which is widely used to assess and rank the flowability of powers. Uniaxial testing involves the construction of a consolidated powder column, which is then fractured through the application of a vertical stress to directly measure UYS.

“This new tester has a number of innovative features that are crucial to ensure reproducible measurement for a wide range of powders, including a unique and novel system for the application of double-ended compression” said Mr Freeman. “Extensive in-house research has shown that the UPT can successfully measure and rank sc, compressibility and density of many industrially relevant powders, even those that are relatively free-flowing.”

The new instrument is available in either a manual or an advanced version. Both deliver the same data with the same high repeatability, while the advanced version also offers the advantage of increased automation and reduced operator input.

“We’re delighted to extend our range of powder testing equipment with new instruments that address an industrial need for simple, easy-to-interpret, low cost testing,” said Mr Freeman. “The UPT is unique in enabling our customers to reliably access uniaxial testing, and comes with all the assurance of the reputation of Freeman Technology for quality powder testing instruments, extensive application know how and exemplary service.”
