Presterilized filter units with cellulose acetate membranes are ideal for proteinaceous solutions. Units feature a 1 1/2-turn threaded screw closure that guarantees a leakproof seal and eliminates pH shift in receivers.
For easy identification, membrane pore size and membrane type are marked on the yellow collar. Polystyrene receiver has molded graduations, quick-disconnect tubing adapter and cellulosic vent plug. Adapter accepts 1/4 to 3/8” tubing. Padless membrane support plate minimizes foaming. Certified sterile, non-cytotoxic and non-pyrogenic. Supplied with dust cover.
Nalgene filterware is for laboratory use only. Not for in vitro diagnosis or parenterals.
