The new 1ml shear cell accessory extends the range of shear cells for the FT4 powder rheometer, adding to the existing 85ml and 10ml capacity systems.
Freeman Technology is launching a new accessory for the FT4 powder rheometer at this year's annual meeting and exposition of the American Association of Pharmaceutical Scientists (11-14 Nov 2007; San Diego, USA).
The new 1ml shear cell will allow fully automated shear testing of powders on the FT4 using the minimum possible sample volume.
This is a major consideration for many pharmaceutical materials and will allow the study of powder flowability characteristics at an early stage in formulation development when only small volumes may be available.
Widely used within the pharmaceutical industry, the FT4 is an automated, precision-engineered system designed for the rapid and consistent characterisation of powders.
Centred on a revolutionary, patented design it offers dynamic, shear and bulk property measurement in a single system and is a universal powder tester.
This integrated testing approach allows the characterisation and understanding of powders in industrially relevant ways.
This makes the FT4 a tool for formulation and process development, troubleshooting and QC applications.
Closely defined measurement protocols, including a unique pre-measurement conditioning step give the FT4 unsurpassed reproducibility and accuracy, maximising its ability to differentiate between samples says Freeman Technology.
It can therefore be used to accurately quantify the impact on powder behaviour of a range of factors including aeration, segregation, consolidation and composition.
