Recommended for large sample volumes, liquids with a heavy particulate load and viscous liquids when a high flow rate is required. Can provide filtration rates up to four times faster than 47 mm assemblies due to its larger filter area. Feature a unique screw collar design for connecting the funnel to the support base providing a more even seal of membrane filter compared to the traditional aluminum clamp. Glass components are manufactured from DWK Life Sciences (Wheaton) 33 low extractable borosilicate glass that conforms to USP Type I and ASTM E 438 Type I, Class A requirements. Flasks have a No. 2 hose connection for ¹/₄No. (6 mm) I.D. tubing. Recommended for routine filtration of aqueous solutions. No. 8 silicone stopper makes the connection to a standard 1L Erlenmeyer-style filtration flask. Includes a 1L funnel with screw collar, glass support base, filter support (either fritted glass, stainless steel or PTFE) and a No. 8 silicone stopper. Flask in photo is not included.
