Membrane Filters

OE67 0.45µm cellulose acetate membrane filters exhibit very low protein binding capacity. They are hydrophilic making them suitable for aqueous and alcoholic media. The cellulose acetate membranes have improved solvent resistance, particularly to low molecular weight alcohols and increased heat resistance. With high physical strength, the membrane filters can be used up to 180...

The Anopore® Anodisc inorganic membrane is ideal for a wide range of laboratory filtration applications. This unique material has a precise, non-deformable honeycomb pore structure with no lateral crossovers between individual pores. Filters at precisely the stated cutoff, allowing no larger sized particles to pass through the membrane. The Anopore® inorganic membrane is...

Whatman black and green mixed ester membranes are composed of cellulose acetate (20%) and cellulose nitrate (80%). These membranes are characterized by a smoother and more uniform surface than pure nitrocellulose filters. Also, the color contrast provided by the filter surface facilitates particle detection and minimizes eye fatigue. Compared to pure nitrocellulose filters,...
