Filters are essential in research laboratories and many other industries for removing particulates and creating environments conducive to a wide array of experiments and procedures. The devices come in different forms including in-line filters, paper discs, small capsules, and large ventilation panels. Filters also purify and concentrate the liquids and gases required for testing. For air, this means removing pollution, moisture, and solid airborne particulates; for liquids, this means removing impurities and small contaminants.

Cellulose Acetate Membrane Filters, Whatman®
Supplier: Cytiva
Membranes are made from pure cellulose acetate, making them ideal for biological and clinical analysis, sterility tests, and scintillation measurements. Filters exhibit very low protein binding capacity and 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. The membrane filters exhibit high physical strength and can be used up to 180°C (356°F), making them suitable for hot gases and allowing them to be sterilized by all methods without sacrificing the integrity of the membrane.
