Product Description
Even support under the membrane is what keeps a filter from tearing and flow from channeling. This 47 mm fritted support base provides a flat, porous glass surface beneath the filter, spreading vacuum uniformly so samples pass through cleanly in routine membrane filtration work.
This listing is for Wheaton catalog number 419352: 47 mm Fritted Support Base. The base carries a fritted glass disc that seats the 47 mm membrane, with a funnel clamped on top and a stem that fits into a filter flask stopper. Built from borosilicate glass, it is chemically resistant and reusable. Use it as a replacement part or to build an additional 47 mm filtration station with a matching funnel and clamp. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
