90mm Filtration Assembly with No. 8 Stopper Connections

By Wheaton Science Products
90mm Filtration Assembly with No. 8 Stopper Connections

These 90mm filtration assemblies are recommended for large sample volumes, liquids with a heavy particulate load, and viscous liquids when you require a high flow rate. Because of its larger filter area, the 90mm assembly can provide filtration rates up to four times faster than 47mm assemblies. Wheaton Science Products 90mm filtration assemblies use a unique screw collar design for connecting the funnel to the support base. Compared to the traditional aluminum clamp, this design provides a more even seal of membrane filter in place. The glass components are manufactured from Wheaton 33 low extractable borosilicate glass (meets ASTM Type I Class A and USP Type I standards). Flasks have a #2 hose connection for 1/4" (6 mm) I.D. tubing.
