Stainless steel type 304 or 316 minimizes resistance and maximizes flow rate
Pressure filtration holders maximize flow rates by applying positive pressure to the fluid over a broad membrane surface. Holders are autoclavable with one filter membrane that is sealed with removable wing nuts. All holders vent to release pressure.
Holders have PTFE gaskets, silicone O-rings, and PTFE-coated photoetched stainless steel support screens to prevent nitrocellulose membranes from sticking.
Stainless Steel Holders with Reservoir let you filter samples without a separate pressure-dispensing vessel. The 47-mm holder has a 200-mL capacity, the 90-mm holder has a 750-mL capacity, and the 142-mm holders have a 1500-mL capacity.
