NALGENE® DS0210 Membrane Filters, cellulose acetate (CA)

Filter of choice for cold sterilization of proteinaceous solutions. Low adsorption of proteins from serum or culture media so filtration is more efficient. Cellulose acetate has excellent thermal properties and is autoclavable to 125°C (must be wet when autoclaved). Has superior chemical resistance to alcohol and oil; can even be used in short-term contact with methyl ethyl ketone. Suited for liquid scintillation studies. Can be cleared for direct observation using paraffin or almond oil. Non-sterile. Autoclavable.
