Product Description
Clear, particle-free filtrate for everyday vacuum filtration comes easily with an all-glass setup built around a standard 47 mm membrane. This assembly pairs a 300 mL funnel with a 1000 mL receiving flask, giving you a dependable general-purpose system for buffers, media and analytical samples.
This listing is for Wheaton catalog number 419520-47: 47mm Filtration Assembly With GL45 Thread Connection and Fritted Glass Support, 1000 mL. Glass parts are made from low-extractable borosilicate glass that meets USP Type I and ASTM E438 Type I, Class A requirements. A fritted glass support with 40-60 micron porosity holds the membrane flat, the funnel connects to the receiver through a GL45 thread, and a #2 hose barb accepts 1/4 in. (6 mm) I.D. vacuum tubing. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
