Made with 100% borosilicated microglass fibers, these filters offer an excellent level of very small particles retention (up to 0.7µm) and a large loading capacity. They are particularly suitable for micro-filtration of air, gases and liquids as they resist to 500°C and are compatible to most solvents and reagents (except hydrofluoric acid). Glass microfiber without binder, pore size 2.7µm, for universal membrane pre-filtration (very fast filtration and high loading capacity).
