Spectrum® Hydrophilic Mixed Cellulose Ester Membranes

Biologically inert mixtures of cellulose acetate and cellulose nitrate result in membranes with a smoother and more uniform surface than pure nitrocellulose filters.
These filters are easy to handle, with less cracking and fracturing than traditional CN membranes. Surface is pure with no additional smoothing treatment or surfactants.

Features:
• Available in porosities of 0.22 µm, 0.45 µm and 0.80 µm
• Non-sterile version is bright white, no grid pattern imprinted
• Pre-sterilized version using gamma irradiation and individually wrapped
• Accurate pore structure and highly regulated density for accuracy
• Medium-fast flow rates with reproducible loading capacities
• Clean-edge processing ensures easy separation from stack and less curl
• Autoclavable
