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: 180 °C (356 °F)
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.
