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 0.7µm, highly efficient for very small particles (very good flow rate and high loading capacity), filtration for HPLC.
