Product Description
Membranes that stick to glass after autoclaving can tear and ruin a sample. This 47 mm fritted support base has a PTFE-faced sealing surface that releases filters cleanly, making it a dependable replacement for assemblies that are sterilized with the membrane in place.
This listing is for Wheaton catalog number 419372: 47 mm Fritted Support Base with PTFE Face. The base combines a fritted glass disc for even membrane support with a PTFE-faced rim where the funnel meets it. A clamp holds the matching PTFE-faced funnel on top, and the stem seats in a filter flask stopper. Use it to replace a damaged base or to equip another sterile filtration station. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
