GVS Filter, Disk, NC, 0.45µm, White, Individually Pack without Pad, Gridded, Sterile, 47mm S1, 250/PK 1216733

GVS mixed cellulose ether (MCE) membranes are unsupported hydrophilic membranes. Its fast flow rates and high throughput make MCE membranes ideal for use in bioburden and sterility testing. Consistent uniformity for improved control and performance GVS MCE membranes consist of a mixture of inert cellulose nitrate and cellulose acetate polymers. The uniform microporous structure of these filters allows for the fastest flow rates and highest throughput available in a membrane filter. It is hydrophilic with non-cytotoxic wetting agents, resulting in extractable levels of less than 4% by weight. These membranes are autoclaved at 121°C (250°F) for 20 minutes. The shelf life of a sterilized product is 24 months from the date of sterilization.
