NALGENE® 163, 164 Media-Plus Filter Units – 500 and 1000mL Capacity, polystyrene housing, 90mm nylon membrane

Ideal for tissue-culture applications with sensitive cell lines or where a wetting agent may cause problems. Disposable, sterile filter units with large 90mm diameter (57.2cm² usable surface area) nylon membrane provide good flow rates and throughput. Tissue culture-grade nylon membrane has extremely low levels of extractables (less than 0.5% by weight), is inherently hydrophilic and contains no wetting agents. 1-½ turn leakproof threaded screw closure eliminates pH shift in receivers. Side-arm features a cellulosic vent plug and a quick-disconnect tubing adapter. Non-cytotoxic. Non-pyrogenic. Sterile/Graduated.
