Product Description
An all-glass joint between filter base and flask helps keep filtrate free of elastomer contaminants. This 47 mm fritted support base ends in a 40/35 ground glass joint, making it the replacement part for ground-joint filtration assemblies used with solvents and sensitive analyses.
This listing is for Wheaton catalog number 419382: 47 mm Fritted Support Base with 40/35 Joint. A fritted glass disc supports the 47 mm membrane uniformly, while the outer 40/35 joint seats directly into a matching filter flask. A clamp holds the funnel on top. Replace a damaged base with this part, or combine it with a funnel, clamp and flask to assemble an additional all-glass filtration station. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
