ST69 Membrane Circles, Cellulose acetate, 1.2µm, 47mm 100/pk

Cytiva's Whatman cellulose acetate membrane filters have very low protein binding, which minimizes sample loss when filtering protein-based aqueous samples.

• 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

High chemical resistance membranes
Due to their high chemical resistance, cellulose acetate membrane filters from Cytiva's business 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.
