Hopefully you dont need to filtrate! Steroids can bind to albumin in culture media, so that whether filtration is necessary, low-binding protein filters are recommended in culture media with

Where sterility will be claimed, regulatory agencies worldwide require that the sterilizing-grade filter(s) be integrity tested to ensure filter performance is verified prior to and after filter use. Sterilizing filtration is now commonplace in pharmaceutical manufacturing and is used in order to prevent microbial contamination negatively impacting drug quality and, more importantly, to ensure patient safety. The selection of filters for sterilization must account for the size range of the contaminants to be excluded.

2019-02-05 · This configuration did not protect the sterile nature of the filtration system, as exposure to the environment was inevitable during operation. GSK's facility required a new system that was fully integrated and completely automated while being capable of protecting the sterile boundary during filter integrity testing.

Available in PES, CN, SFCA and Nylon membranes. Devices are color coded according to membrane. Devices feature the fastest flow rate and lowest clogging of comparable alternatives. 0.1μm PES available for mycoplasma protection. 0.2μm PES devices are stem cell and mouse embryonic assay (MEA) tested. Guidance for Industry Sterile Drug Products Produced by Aseptic Processing — Current Good Manufacturing Practice U.S. Department of Health and Human Services In most cases, we sterile filter the finished mixed product ahead of filling. We have established procedures for sterile filtering through several different types and sizes of filters.

The media allows for high flow rates and low pressure drop. Housing Material: Polypropylene (PP) microbiological aspects of sterile gas filtration. In addi- tion, a method for testing the microbial retention charac- teristics of filters in gas filtration is described. It is convenient to classify sterile filtration processes by the type of fluid being processed. For example, fluids are generally classified as being either gases or liquids.
