Product Description
Aggressive solvents, strong acids and venting jobs call for a membrane that water cannot wet. CELLTREAT PTFE filters use a hydrophobic polytetrafluoroethylene membrane with excellent chemical and temperature resistance.
This listing is for CELLTREAT catalog number 229731, the PTFE Vent Filter, 0.22µm, 50mm, Barb-Barb, sold as a full case of 10 (10/Bag). Syringe filters come in 0.22 and 0.45µm ratings with 13mm or 30mm diameters, molded into white polypropylene housings with a female luer-lock inlet and male luer slip outlet. A sterile 50mm, 0.22µm PTFE vent filter with tiered barb-barb hose connections is also available for aseptic venting and vacuum pump protection. All are sterile, non-pyrogenic and RNase/DNase free, and each item is sold by the full case. LIGHT LABS ships CELLTREAT consumables by the full case from Englewood, Colorado.
