Product Description
Filtering organic solvents and HPLC mobile phases calls for a clean, all-glass vacuum path and plenty of filter area. This 90 mm assembly delivers both, filtering up to four times faster than 47 mm units while its ground glass connection avoids the phthalate contamination that silicone or neoprene stoppers can introduce.
This listing is for Wheaton catalog number 419460: 90mm Filtration Assembly With No. 8 Stopper and 40/35 Connection, With Stainless Steel Support. A 1000 mL funnel attaches to the support base with a screw collar for an even membrane seal, and the base joins the flask through a 40/35 ground joint. A drip tip extends below the hose connection to keep filtrate out of the vacuum line. Choose stainless steel, PTFE or removable glass frit support, all in WHEATON 33 low extractable borosilicate. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
