Cytiva's Whatman™ Vacuum Type Glass Membrane Holders

Produced from borosilicate glass and available with a choice of support screen. Suitable for aqueous and organic solvent filtration. The funnel seal ensures that the sample does not bypass the membrane and that particulates are retained on the surface of the membrane.

The sintered glass support is recommended for filtration and biological analysis. The 304 stainless steel support screen is suitable for use with proteinaceous solutions.

Chemical resistant to most aqueous and organic solutions as well as acid and caustic solution resistant. Applications include: - food & beverage (e.g cold sludge in beer; ice cream), pharmaceuticals and cosmetics, water and wastewater, residue analytics and precipitation analysis, contamination tests (e.g in electroplating), microbiological, biochemical, and hydrobiological detection, radiochemical tests, particle analysis in sensitive areas of electronics, aviation, and space travel.
