Wheaton® 90 mm Vacuum Filter Assemblies, 40/35

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 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 organic solvents, corrosive liquids and the removal of particulates from HPLC solvents. Ground glass connection eliminates phthalate contamination that can occur from silicone or neoprene stoppers. Drip tip on the support bases extends below the hose connection preventing filtrate from entering the vacuum line. A filtration flask with a standard taper 40/35 inner joint is required.
