Featuring a supported, hydrophilic cellulose acetate medium with naturally low protein binding, these 47mm membrane discs deliver a 0.8um pore size for clarification and particulate removal across aqueous and proteinaceous samples. The cellulose acetate is internally supported by an inert polyester web, giving each membrane exceptional dimensional stability that resists cracking, tearing, and distortion during handling and creasing. The low binding character maximizes recovery, making the membrane well suited to applications where retaining proteins in solution is critical. Supplied nonsterile in packs of 100.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic surface wets spontaneously with water and aqueous solutions for consistent bulk flow.
- Naturally low protein binding minimizes retention of proteins in solution and supports maximum sample recovery.
- Supported construction with an inert polyester web provides strength and dimensional stability to prevent cracking, tearing, and curling.
- Higher throughput reduces the number of filter changes required during filtration of proteinaceous solutions.
- Thermally stable and able to withstand autoclaving or steam sterilization up to 135C (274F).
Key Construction Characteristics
- Material: pure cellulose acetate on an integral nonwoven polyester support.
- Pore size: 0.8um nominal rating with a 47mm membrane diameter.
- Sterility: nonsterile, supplied 100 per pack.
- Format: plain (not gridded) flat membrane disc.
The uniform microporous structure delivers dependable flow and clean separations while protecting downstream sample integrity. Low binding and consistent retention support reproducible results across repeated filtrations. The supported polyester web maintains membrane integrity under handling and pressure for reliable performance.
