Tips For Getting The Best Results From Your FeSSIF/FaSSIF Media
At Phares, we are continually conducting research into the field of Biorelevant Media for industrial application. It is part of our customer care policy to update our customers with this information so you can benefit from our latest findings.
*Use HPLC as your analytical tool*
HPLC or specialist UV equipment is recommended as an analytical tool for more accurate quantitative drug analysis in the presence of FaSSIF and FeSSIF media to eliminate possible UV interference.
*Make FaSSIF and FeSSIF freshly to reduce the risk of microbial spoilage or physicochemical changes*
As FaSSIF and FeSSIF are so quick and easy to prepare using SIF Powder you can make it freshly, eliminating the need to store the media.
Tips For Preparing FaSSIF and FeSSIF Media With Reproducible Physical Properties
*Equilibrate FaSSIF media to obtain a stable particle size*
We recommend in our Preparation Protocol equilibrating this media for 2 hours after preparation before use to obtain a stable particle size.
*Avoid storing FaSSIF media in the refrigerator*
We suggest avoiding storage in the refrigerator as this can change the particle size of FaSSIF.
