‘‘’’
Tom Dennison, Aston University, United Kingdom
’’
‘‘We use FaSSIF/FeSSIF/FaSSGF powder in our lab. The biggest benefit of using the powder is that it is very flexible and compatible with different buffers. We can then create Biorevelant Media at different pHs and buffer capacities. The powder is very easy to use. The biorelevant.com website provides a great resource in terms of preparing and using the media. The staff are very friendly and work efficiently!

‘‘’’
Aurigene Discovery Technologies, India
’’
‘‘Now there is only one way of preparation for us – FaSSIF/FeSSIF/FaSSGF, because there are only benefits. It saves a lot of time (by our calculations more than 50%) and the best part is very simple preparation. It's also very user friendly because with powder we can prepare low volumes of media (e.g. for solubility testing).
‘‘’’
Krka, Slovenia
’’
‘‘The powder from biorelevant.com provides a very practical and economical way to produce the FaSSIF medium.
‘‘’’
Iris Duarte, Hovione Farmaciência SA, Portugal
’’
‘‘We use powder from biorelevant.com for in vitro dissolution testing of the drugs in Biorelevant Media and it is very helpful to predict the in vivo behaviour of the drugs in this way. Preparation of the media is very easy and time saving with this powder.
‘‘’’
Dr. Asuman AYBEY DOĞANAY, Ilko Ilac, Turkey
’’
‘‘FaSSIF/FeSSIF/FaSSGF is very useful in the lab, especially during the development of a new method. Because it is so easy and relatively fast to make biorelevant media, you can focus more on the setup of a study.
‘‘’’
Cecilie Madsen, University of Copenhagen, Denmark
’’
‘‘The powder is very good, it is simple to use and stable.
‘‘’’
Debiopharm Group, Switzerland
’’
‘‘Service is the best, efficient and reliable. The powder from biorelevant.com is the ONLY material that we use.
‘‘’’
Abbott Laboratories, Singapore
’’
‘‘We use the powder for preparation of different biorelevant media (FaSSGF, FaSSIF and FeSSIF) for solubility and dissolution studies. The method of preparation of the media is very easy to follow and we get biorelevant media of high quality. The short time needed for their preparation and the reproducibility of the media are great advantages of this product. The support from the biorelevant.com team is excellent!
‘‘’’

‘‘’’
Johnny Brendell, Quality Chemical Laboratories, USA
’’
‘‘As a contract research and development company, obtaining solubility data in biorelevant media of our clients' drug molecules is essential in order to fully understand the challenges we are facing for oral drug development. This data also allows us to design our formulations intelligently based upon the physico-chemical properties observed. In order to design a robust formulation it is imperative that the preformulation data is also robust and the consistent quality of the powders from biorelevant.com allows us to obtain fantastic reproducibility; in addition, as they are so easy to prepare the time saving benefits can be passed on to our clients, both from a cost and time perspective.
‘‘’’
Dr Mark Saunders, Kuecept Ltd, United Kingdom
’’
‘‘The products are very helpful in regard to the amount of work needed for preparing the solutions. In addition, one does not have to worry for other potential issues, e.g. residual dichloromethane amounts in the rotavap.
‘‘’’
Prof Christos Reppas, University of Athens, Greece
’’
‘‘So far so good! Our order arrived promptly... the powder was easy to store, handle and transfer into the SGF media.
‘‘’’
Collegium Pharmaceutical, USA
’’
‘‘We found the powder offered a very easy, convenient and reproducible way of preparing biorelevant media. For us it was an easy entry into this field and is now an ideal support during the preparation of bioequivalence studies.
‘‘’’
Ratiopharm, Germany
’’
‘‘I first heard about FaSSIF/FeSSIF/FaSSGF when I started working on drug dissolution studies at Nanocopoeia. I think the powder is an excellent tool in drug dissolution and absorption studies, and that it's extremely easy to use. From what I've seen in the literature, it seems as though its use in absorption studies is the industry standard.
‘‘’’
Cole J. Batty, Nanocopoeia Inc., USA
’’
‘‘It took only 10 minutes to prepare FaSSIF, this powder makes it easy to use biorelevant media.
‘‘’’
Shionogi & Co. Ltd, Japan, Japan
’’
‘‘FaSSIF/FeSSIF/FaSSGF is a very easy substance to use in our lab. It is easy to store and the website offers a great resource for actually making the media.
‘‘’’
Metrics Inc, USA
’’
‘‘We would consider the reproducibility of the measurements to be good. We routinely use the powders to make solubility and dissolution measurements in FaSSIF and FeSSIF and find them easy to work with, efficient (in both economic and temporal terms) and reproducible.
‘‘’’
Sirius Analytical, United Kingdom
’’
‘‘I found the powder very easy to work with, and if there is no solubility issue with the drug, it works great and it's comparable to the conventional FaSSIF/FeSSIF media with egg lecithin which are too expensive and hard to work with.
‘‘’’
Watson Laboratories, USA
’’
‘‘The powder is very useful and makes it easy to mimic the gastrointestinal system.
‘‘’’
Ana Rute Neves, ICETA (University of Porto), Portugal
’’
‘‘We routinely use powders from biorelevant.com in our transfer model to examine the supersaturation and precipitation behaviour of poorly soluble drugs. Not only is the media considerably quicker to prepare but its preparation is also significantly safer as dichloromethane is no longer required. We have been very happy using the media so far and will continue to use the powders in the future.
‘‘’’
Dr Edmund Kostewicz, University of Frankfurt, Germany
’’
‘‘The powder is really good to show how API´s and formulations work under biorelevant conditions. It is easy to use and handle. We test many API´s with powder from biorelevant.com and have had good results.
‘‘’’
Merck KGaA , Germany
’’
‘‘I really like it. The powder has been great!
