Cytiva's Whatman cellulose acetate (CA) membrane filters have very low protein binding, which minimizes sample loss when filtering protein-based aqueous samples. Due to their high chemical resistance, these cellulose acetate membrane filters reliably prepare liquid scintillation cocktail for scintillation counter measurement. Additionally, the highly heat resistant Whatman cellulose acetate membranes can filter hot liquids and hot gases.

• Minimal sample loss in protein-based samples due to low protein binding
• Pure cellulose acetate composition, minimizing sample contamination
• Hydrophilic, for use with aqueous and alcoholic media
• High solvent resistance, particularly to low molecular weight alcohols
• High physical strength and a heat resistance up to 180 °C
• Can be sterilized by most common methods without sacrificing membrane integrity

• Grade: OE 67
• Flow rate: 12s/100mL/12,5cm² (Water at deltaP of 0,9 bar)
• Sterilization: Autoclave at 121 °C or 134 °C, or by ethylene oxide
