Our research laboratory aims at responding to the challenges linked with the development and characterization of new materials and particulate solids with controlled usage properties with regard to the processes. We use the Freeman FT4 for different studies. We are very satisfied with the performance of this equipment, the technical support of Freeman, the advice and different discussions about measurements and data interpretation.
FT4 is a very versatile equipment with high degree of precision and reproducibility. It is a very valuable tool for a solid dosage formulator to design and optimize formulations with a small scale (<30 grams) of product. It is also a great tool for process trouble shooting. The technical support from FreemanTechnology is super. You can expect responses within 24 hours.
We've purchased FT4 in our Laboratory of Bulk Materials at Technical University of Ostrava, (Czech Republic) and we're very satisfied. The FT4 Powder Rheometer is a very useful and multilateral device to measure mechanical and physical properties of powders. Especially the combination of user defined advanced tests with aeration unit gives a huge potential in fluidization and pneumatic conveying research.
Our FT4 apparatus is a wonderful equipment allowing fast characterisation of numerous powder flow properties in various conditions of mechanical stresses. Food ingredients, products, and encapsulated powders of diverse origins have been successfully analysed by the numerous standard tests which permitted us to sort investigated food powders according to their ability to flow in low- and high-stress environments, sensitivity to aeration, suitability for compression processes, etc. Besides, user-defined tests, developed with the flawless assistance of Freeman Technology principal application specialist, were employed for instance to investigate aeration behaviour at high flow velocities or “springback” behaviour of compressible, fibrous powders; this possibility to adapt analytical conditions to specific needs makes the FT4 apparatus almost mandatory for food powder applications specialists.
Fantastic training and equipment. Applications Specialist is very friendly and professional and we enjoyed our time with him. The equipment is the most professionally designed and user friendly equipment we've used.
As a particle technology contract manufacturer, my company relies heavily on robust, state of the art analytical techniques for measuring powders. The FT4 fills this role nicely. Its software is by far and away the best software I have used for any analytical instrument. It is very good at walking me through each test setup without adding extra work. I have only been working with the FT4 for a short time, but I feel confident in running each test available on the instrument. Their customer support is always prompt and very helpful when I have questions. Working with Freeman Technology is very easy and pleasant.
We decided to acquire the FT4 Powder Rheometer to investigate its use as a possible powder development tool for additive manufacturing. Several studies in the literature showed its efficiency and its extreme sensitivity to even really small changes in powders characteristics. Conventional flowability characterization techniques such as Hall flowmeter, angle of repose or density-based methods showed their limitations to identify the small powder behavior changes, hence the need of a more sensitive and accurate characterization tool such as the FT4 Powder Rheometer. We just start working with the instrument, it is very well designed and the user interface of the system software is really easy to use. The provided documentation is very detailed and the customer service is outstanding.
The FT4 Powder Rheometer has proven to be useful for formulation/process development as well as describing subtle excipient and powder blend differences. The documentation and the UI make instrument operation incredibly intuitive and easy, even for first-time users. Our interactions with the team at Freeman Tech have all been very positive. They are strong technically and very responsive to requests for technical support and service. After just a few short months of routine use, the FT4 has already been established as a welcome addition to the list of powder characterization tools for research and commercial applications.
