Description
Cellulose acetate membrane filter is an ideal membrane for sterilizing and filtering aqueous solutions such as buffers, serum, culture media, and a wide aperture range. These filters are naturally hydrophilic, providing efficient filtration with low protein adhesion and minimal extractables.
Distinctive Features:
- Naturally hydrophilic, providing efficient filtration for aqueous solutions.
- Low protein binding, making them suitable for protein recovery applications.
- High flow rate and uniform pore structure for effective filtration.
- Strong thermal stability and suitable for positive pressure filtration.
- Resistance to low molecular weight alcohols, hydrocarbons, and oils.
- Low extractables, ensuring clean and consistent results.
- Available in various pore sizes and diameters.
- Suitable for pH 3.5 – 8 aqueous solutions and organic solvents such as oils, ethanol, etc.
Recommended Uses:
- Sterilization and filtration of tissue culture media, buffers, and aqueous reagents.
- Filtration of proteins, enzymes, and other biological samples.
- Diagnostic cytology and recovery of protein solutions.
- Biological and clinical analysis.
- Filtration of buffers, aqueous reagents samples.
- Not recommended for filtering solvents with limited solvent resistance.
