Filter Units - Sterilization, Disposable, Polystyrene, Type S, Cellulose Nitrate Filter, Nalgene®

Description 

A disposable, cellulose nitrate membrane filter assembly ready for immediate use. Pre-sterilized, single-use units are widely used for cold sterilization, clarification, prefiltration and ultra-cleaning of buffers and other aqueous solutions, as well as microbiological media. Triton-free cellulose nitrate membrane has excellent wetting properties and gives fastest flow rates with aqueous solutions. Assembled complete with filter cup, cover, support plate, porous support, suction flask with cotton-plugged sidearm which has a quick disconnect tubing for connecting the unit to a vacuum source, and a 50mm diameter membrane filter. Graduations on both upper and receiver. Upper seperates from receiver with 1 1/2 turns for storage or incubation of filtrate. Closure system provides leakproof seal.

Available with either a plain white membrane (0.20 micron porosity) or a grid membrane (0.45 and 0.80 micron porosities). Pore size and material clearly marked on green collar. Membrane support plates are green on old 115 mL size, clear on new, lower profile 115 mL size. Seperate transparent receivers are available.
