Nalgene® Rapid-Flow™ Filter Units with Nylon Membrane, Sterile

Nalgene® Rapid-Flow™ sterile filter units are manufactured from clear, durable polystyrene polystyrene and include an integrated, removable nylon membrane membrane filter. These Nalgene filter units are specifically designed for cell culture and tissue culture applications. The filter unit upper chamber separates from receiver for easy access to filtrate and the receiver is an ideal filtrate storage vessel. The upper chamber of the filter unit is clearly marked with pore size membrane type catalog number lot number and expiration date. A leakproof screw closure eliminates pH shift in receiver while the padless membrane support minimizes foaming of proteinaceous samples. The nylon membrane filter is naturally hydrophilic and alcohol resistant with low extractables and containing no wetting agents. All filter units are furnished complete with a polystyrene cover, a cellulosic-plugged side arm and a vacuum tubing adapter. Both upper chamber and receiver are graduated and the red color-coded collar identifies which filter material the unit contains. Gamma radiation sterilized and individually wrapped for a 5-year sterile shelf life.
