GVS Mixed Cellulose Esters (MCE) Filtration Membrane is an unsupported, hydrophilic membrane. Its rapid flow rate and high throughput make it ideal for use in bioburden and sterility testing.
GVS MCE Filtration Membranes are composed of a mixture of inert cellulose nitrate and cellulose acetate polymers. The uniform microporous structure of these filters provides the fastest flow rates and highest throughputs available in a membrane filter. They are hydrophilic with a noncytotoxic wetting agent and yield extractable levels of less than 4% of their weight. These membranes are autoclavable at 121°C (250°F) for 20 minutes. Sterilised product lifetime is 24 months from sterilisation date.
- High flow rate: fast filtration rates
- Uniform pore structure: consistent flow and diffusion rates
- Lot-to-lot consistency
- Packaged individually for convenience, handling, economy and integrity
- With an absorbent nutrient pad, the all-in-one pack permits individual testing, eliminating the possibility of contaminating a large supply of pre-sterilised filters
- Filters, pads and envelopes are pre-sterilised by gamma irradiation
- White gridded discs are designed for the recovery and retention of E. coli bacteria in water/waste-water analysis as well as other microbiological tests
- Black MCE filters are specifically manufactured and tested for quality assurance testing in food and beverage analysis; the black filters provide a superb contrast for early and accurate colony counting for total bacteria, yeast and mould organisms
