Glass Microfiber (GMF) depth filters are designed to trap particulates within the random matrix of glass fibers found within the thickness of the media. The efficiency rating of the filters is characteristic of the complex pore structure that develops as the fibers overlap. The purity of the GMF filter is dictated by the presence of, if any, binder material that acts as a strengthening agent and aids in holding the fibers together.
Wyvern Scientific carries a wide range of glass microfiber media grades and devices including cut discs of all sizes, syringe filters and extraction thimbles.
934-AH® - Fine porosity, fast flow rate, with a 1.5µm size particle retention. This material is the standard for suspended particle analysis in water and cell harvesting.
