We use an FT4 Powder Rheometer from Freeman Technology which we’ve had for a couple of years now and we use it to assess every powder used. A unique attraction of the FT4 is that it measures dynamic, shear and bulk powder properties, and in fact, metrics of all three types form our routine screen… If we’re considering a new supplier or a customer brings us a new powder to print with, then we can determine with a high degree of confidence whether it will work and if so how to process it, simply from test data. Without the FT4 this just wasn’t possible.

Andrew Klein - Director of R&D

ExOne Company, USA

The powder tester I use most is our powder rheometer (FT4 Powder Rheometer, Freeman Technology) because we can run a whole gamut of tests with it, and we have, for just about every powder we use. It allows me to investigate flow properties, aeration behaviour and permeability, compressibility and to generate shear data which are particularly helpful for hopper troubleshooting. And it’s easy to use as the instrument pretty much defines what you need to do…. Furthermore, it can be too easy to lose sight of just how much its costing to be sub-optimal with respect to raw materials because of incremental changes, made over time, to cope. For example, we had a legacy product that came with the advice ‘don’t change any of the materials’. Over time that became impractical and as a result tableting rates had steadily decreased by around 50%. When powder testing unlocks throughput gains like this it can easily deliver savings of up to 50 – 100 times the cost of the instrument.

Having the FT4 powder rheometer in our laboratory has broadened our characterization capabilities and enhanced our understanding of a very specialized powder application. The archaic characterization practices of days gone by told us very little about our powder processing results as lot differences were very difficult to quantify by these methods. With the FT4, our ability to see small changes as a result of changing parameters has been greatly improved and we have a very thorough set of data from which to draw conclusions. I am very grateful for the incredible customer support which Freeman Technology supplies on a weekly basis for me. The training provided was incredibly valuable for practical aspects of using the FT4 and data interpretation. I use the FT4 to answer most all of my powder characterization questions and wouldn’t have it any other way. Thank you to Freeman Technology for enriching the capabilities of my laboratory and helping us solve our applied powder application questions.

The delivery of the instrument was perfect in every way.  The instrument is very well designed and seems extremely robust and user friendly.  But most important is the brilliant user interfacing of the system software.  I've never ever had any experience with any other instrument that was so positive as with the FT4 Powder Tester.  The Freeman Technology FT4 powder tester makes my days.

In the pharmaceutical industry, powder characterization is often limited by the availability of rather small quantities of powder. Since a large portion of the pharmaceutical powders demonstrate a cohesive tendency, special attention needs to be paid to the design of any piece of powder characterization equipment. Seen from this perspective, the Freeman Technology FT4 powder tester has demonstrated to be my perfect partner in the powder characterization lab. Its design, functioning and user interfacing are extremely well thought of, and its analytical performance is truly superb. Moreover, at Freeman Technology a team of experts is always available for any immediate scientific and technical support. Having an FT4 powder tester on the lab, I just wonder now how in the world I ever could have worked without it.

The Freeman FT4 Powder Rheometer has become a vital part of our characterisation activities in the Formulation Development and PAT Research Centre in the Institute of Technology, Dublin. Our commercial pharmaceutical projects involve bulk characterisation measurements of both excipients and solid dose formulations. The FT4 has proven to be exceptionally reliable and capable of an impressive range of Bulk and Dynamic Powder measurements and makes a significant contribution in powder characterisation. In addition the User Interface is very intuitive and easy to use. Back up service and technical advice is very professional and the support services from Freeman are top class. 

Dr Ed Carey - Senior Lecturer in Chemistry

Institute of Technology Tallaght (IIT Dublin), Republic of Ireland

The Freeman FT-4 is excellent hardware, but the real advantage is in the software and support.  It is easy (relativity) to make good laboratory hardware, but as with most pieces of equipment the secret lies in the software and ease of operation.  Freeman has taken what is learned based on user feedback and incorporated this learning directly into the software.  The application support after the sale is also a major factor.  They truly want the users to succeed with the FT-4 in understanding the powder properties.  We do to work with typical powders and they have been very helpful designing custom test procedures with us to help understand what our powder is actually going through. 

Rob Romeo - Advanced Technical Service Technologist

Dyneon LLC (3M), USA

The FT4 Rheometer is complementing our laboratory for 10 years, where we are using about 20 other laboratory apparatuses to determine the product properties of bulk solids. This equipment is necessary to choose the appropriate filling technology on basis  of a product sample. The FT4 Rheometer enables us to determine the characteristic values of flowability quickly and reproducibly. The simple handling and the automated procedure minimize the sources of error by the operator. The results like maximum energy and torque are directly integrated in the product analysis. The results of the FT4 Rheometer are an inherent part of our product analysis. With help of the generated curve the procedure can easily be read out. This makes it easier to recognize and compare quality variations of different products. The option to aerate the product from below allows to recognize what forces are necessary to move the product in normal and aerated condition. The simple handling in shear test and the wide spectrum of applications make the FT4 absolutely essential. Except for the calibration which can be carried out independently, there is practically no maintenance  needed. The FT4 Rheometer works very reliably so that we haven’t experienced any failure so far.

Dr Thomas Hilling - Manager, Research & Development Center

Haver & Boecker OHG, Germany

The FT4 Powder Rheometer has become an essential tool to investigate the flow and caking behavior of our products. It is a versatile instrument that can be adapted to our needs (aeration, shear cell  testing, etc). The modularity of the software allowed us to customize to a great level of detail each test. Whenever needed, some accessories were available from or even custom built by Freeman Technology. Their customer service is very good, we have always had a quick response and our requests are met straight away treated by experts with whom communication has been very valuable.

Edgar Chavez - Group Leader, Food Physics & Structure, Science Department

Nestle Orbe, Switzerland

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.

Eli Crossman - Senior Scientist

Procter & Gamble, USA

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.

Salah Eddine Brika - PhD Candidate

 The ability to modify the test set-up with different accessories helps investigating versatile effects of changes in powder composition or powder processing. Especially, the testing of aerated powders and studying the changes in shear behaviour of surface modified particles has helped us with regards to an improved understanding of subsequent de-agglomeration of powders in inhalation drug products. In combination with the above-average support provided by Freeman Technology, the universal powder tester has become a highly appreciated test equipment in our labs. The FT4 Powder Rheometer is a great tool to study various aspects of complex bulk powder properties.

The software and procedures are the best designed software I have worked with for lab equipment.  The instrument is extremely user friendly and it took only minutes to run our 1st test.  The Product Manager and the rest of the Freeman team were extremely prompt and responsive.

Dr Steven Vilt - Senior Engineer, Pharmaceutical, Technical Operations

BASF Corporation

Since we’ve acquired the FT-4 (the first one in Brazil by the way) many companies have contacted us showing their problems in handling solids materials and asking for solutions. This has showed us how bulk solids handling is misunderstood in our country. Very basic scientific works were developed at FEI to help our collaborators that consisted only in well characterised powders. In this task the FT-4 was fabulous because it offers the best possible measurement capability. It was evident to us that a free flowing powder hasn’t necessarily got better permeability, a test till now unknown by so many companies that becomes indispensable. 

Prof Dr Rodrigo Condotta - Chemical Engineering Department

FEI - Fundacao Educacional Inaciana - Pe. Saboia de Medeiros, Brazil

Dr Raja S Rao - Senior Seed Technology Scientist

Monsanto Company, USA

At AEL Mining Services we have used the FT4 to identify the best binder for spray drying pyrotechnic delay compositions. The FT4 also allowed us to optimise the binder content in the pyrotechnic formulation and minimise breaking of the spray dried particles during processing. The FT4 was also used to identify the most suitable flow agent for PETN (pentaerythritoltetranitrate) which is used as the base charge in detonators manufactured on automated detonator manufacturing plant. The FT4 enabled us to optimise the quantity of flow additive added as well as the mixing time. We were also able to identify differences in PETN batches produced at AEL Mining Services w.r.t. conditioned bulk density, specific energy, basic flow energy and stability. Personally I have found after sales service excellent w.r.t. training done at Freeman Technology in the UK, servicing and updating of our instrument in South Africa and assistance from Freeman Technology experts in developing specific tests for the explosives industry.

Etienne Cloete - Senior Technologist
