Wheaton 90mm vacuum filter holder assemblies are recommended for large sample volumes, liquids with a heavy particulate load and viscous liquids when a high flow rate is required. Ideal for routine filtration of aqueous solutions. 90mm filter holders provide filtration rates up to four times faster than 47mm assemblies due to its larger filter area. They also 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. Vacuum filter holder assembly includes a 1-liter glass funnel with screw collar, glass support base, stainless steel filter support and a 40/35 [ST] joint connection. Filtering flask has a #2 hose connection for 1/4-inch I.D. tubing. The 40/35 [ST] joint connection makes the connection to the 1-liter graduated glass filtering flask with the same size inner joint.
