FaSSIF-V2: Product Benefits

Biorelevant Media simulate gut fluids before (fasted) and after (fed) eating food. They are really useful for predicting what will happen to your product when it enters the gastro-intestinal tract. In the past the media were notoriously difficult to prepare.

In 2007 we solved this problem by inventing a product that makes Biorelevant Media instantly. In 2013, we introduced a new line to make the second version of FaSSIF. This update is based on physiological data from more recent literature*. It contains exactly the same ingredients as the first version of FaSSIF (bile salts and lecithin) but in a revised ratio (15:1 rather than 4:1).

There are many benefits of using our product to make FaSSIF-V2:

Quick and easy to use

Simply add powder to buffer and you're ready to go...

Reproducible results

We use the highest grade of ingredients and double check their purity before manufacture. The powders are made in our own facility in London so we can control every aspect of their production. Once this process is complete, they are only released after rigorous analysis by an independent laboratory in Germany. These steps ensure you will get highly reproducible results from our products every time you use them.

Great value

3 bottle sizes are available so whether you want to make 10 mL or 1000 L of FaSSIF-V2, we can satisfy your requirements. The powder has a long shelf life of 18 months so there is no need for any waste. We also offer money-saving 4 packs.

“FaSSIF-V2 powder is incredibly easy to use and the long shelf-life helps to minimize waste. FaSSIF-V2 is a convenient choice of biorelevant media for use in GI dissolution and supersaturation experiments where in-situ UV absorbance measurement is required.”
