Presterilized filter units with surfactant-free cellulose acetate membranes are ideal for proteinaceous solutions.

• Yellow collar
• Polystyrene receiver bottle has tapered sides and grips for ease of handling
• Wide base ensures benchtop stability
• Certified sterile, non-cytotoxic, and non-pyrogenic

Membrane pore size, membrane type, lot number, catalog number, and expiration date are marked on the filter cup for easy identification. Filter also features molded graduations, quick-disconnect tubing adapter, and cellulosic vent plug. Adapter accepts 6.35 to 9.5 mm (¹/₄ to ³/₈") tubing. Padless membrane support plate minimizes foaming.

Filters are low protein binding and have no wetting agent. Units feature a 1 ¹/₂-turn threaded screw closure that guarantees a leakproof seal and eliminates pH shift in receiver storage bottles.
