Press Release Summary:
Available in manual or advanced version, Uniaxial Powder Tester measures unconfined yield strength, offering value to engineers and QC analysts working across number of industries, from bulk solids handling to pharmaceuticals. Uniaxial testing involves construction of consolidated powder column, which is then fractured through application of vertical stress to directly measure UYS. Tester's system for application of double-ended compression ensures reproducible measurements.

Freeman Technology Launches a New Ground-breaking Powder Tester for Cost-efficient Industrial Measurement
Tewkesbury, UK – Freeman Technology, a global leader in powder testing technology, has launched the Uniaxial Powder Tester (UPT), the world’s first stand-alone uniaxial tester for simple, sensitive and cost-efficient powder characterisation. Developed in collaboration with the University of Edinburgh and a major industrial powder processor, the new tester delivers automated, highly repeatable measurement and provides a cost effective alternative to traditional powder testing techniques. It offers significant value to engineers and QC analysts working across a number of industries, from bulk solids handling to pharmaceuticals.
“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 (UYS), a parameter typically derived indirectly via biaxial shear cell analysis, which is widely used to assess and rank the flowability of powders. 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, also known as óc. Fundamental to the successful implementation of the technique is the construction of a uniformly consolidated powder column, and subsequent removal of the containing sleeve with minimal disturbance of the compacted column.
“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 óc, 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.”

About Freeman Technology
Freeman Technology specialises in systems for measuring the flow properties of powders and has over a decade of experience in powder flow and powder characterisation. The company invests significantly in R&D and applications development, and provides detailed know-how alongside its universal powder tester, the FT4 Powder Rheometer®. Expert teams guide and support users around the world in addressing their individual powder challenges, focusing on delivering the most relevant information for the process. The result is world-leading solutions for understanding powder behaviour - in development, formulation, scale-up, processing, quality control, or anywhere that powders have a role.
The FT4 Powder Rheometer uses patented dynamic methodology, a fully automated shear cell (in accordance with ASTM D7891) and several bulk property tests, including density, compressibility and permeability, to quantify powder properties in terms of flow and processability. Systems are installed around the world in the chemical, pharmaceutical, toners, foods, powder coatings, metals, ceramics, cosmetics, and many other industries. They deliver data that maximise process and product understanding, accelerating R&D and formulation towards successful commercialisation, and supporting the long term optimisation of powder processes.
Freeman Technology was founded in 1989 as a developer of automated testing systems for materials characterisation, and has focused exclusively on powders since the late 1990s. The company’s R&D, manufacturing and commercial headquarters are in Gloucestershire, UK, with operations in the USA and China, and distribution partners in Brazil, France, India, Ireland, Japan, Malaysia, Scandinavia, Singapore, Taiwan and Thailand.
In 2007 the company received the Queen’s Award for Enterprise in Innovation and in 2012 the Queen’s Award for Enterprise in International Trade. www.freemantech.co.uk
