Product Description
Viscous or protein-rich solutions can clog a glass frit quickly, and ultra-clean filtrate demands a support that sheds nothing. This 47 mm assembly uses a stainless steel screen support to handle those jobs, pairing a 300 mL funnel with a 1000 mL receiver for dependable vacuum filtration.
This listing is for Wheaton catalog number 419530-47: 47mm Filtration Assembly With GL45 Thread Connection and Stainless Steel Support, 1000 mL. Glass components are made from low-extractable borosilicate glass meeting USP Type I and ASTM E438 Type I, Class A. The funnel connects to the bottle through a polybutylene terephthalate (PBT) cap with a PTFE-faced silicone sealing ring on a GL45 thread, and the hose connection takes 1/4 in. I.D. vacuum tubing. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
