Product Description
Large volumes and heavily loaded samples move far faster across a bigger membrane. With its 90 mm filter area, this assembly can filter up to four times faster than 47 mm holders, making it a strong choice for routine aqueous filtration, viscous liquids and samples carrying heavy particulate.
This listing is for Wheaton catalog number 419450: 90mm Filtration Assembly With No. 8 Stopper, Complete Unit With Stainless Steel Support, 1000 mL. A 1000 mL funnel joins the support base with a screw collar that seals the membrane more evenly than a traditional aluminum clamp. Choose stainless steel, PTFE or removable glass frit support. A No. 8 silicone stopper fits standard filter flasks, sold separately with #2 hose connections for 1/4 in ID tubing. Glass meets USP Type I and ASTM E438 Type I, Class A. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
