Mixed Cellulose Esters Membrane, MicronSep™, GVS Life Science
Mixed cellulose esters (MCE) filtration membrane is an unsupported, hydrophilic membrane. Its rapid flow rate and high throughput make it ideal for use in diagnostic kit manufacturing applications.
- High flow rate: provides fast filtration rates
- Uniform pore structure: provides consistent flow and diffusion rates
- Lot-to-lot consistency
- Sterilization: Gamma irradiation or ethylene oxide (EtO)
- Thickness: 100 to 190 μm
- Maximum operating temperature: 356 °F (180 °C)
They 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. Because they are biologically inert, they are ideal for a wide range of clarification, sterilization and analytical applications such as: microbiological analysis, clarification or sterilization of aqueous solutions, industrial hygiene applications, silt density index and particulate-matter analysis.
For gravimetric analysis using ashing techniques, yield a residue or less than 0.045% of their initial weight. 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. Sterilized product lifetime is 24 months from sterilization date.
Extractables are less than 4% with sealing compatibility by ultrasonic, heat, radio frequency and also insert molding. BSA protein binding is approximately 160 μg/cm² (depending on pore size).
Certifications: Passed USP Class VI testing.
