Glass Fibre Filters
Made with 100% borosilicate glass microfibres & binder free. Due to their fine fibres, glass microfibre filters allow high efficiency rates even down to the submicronic range, combined with good permeability & high holding capacity. Non-hygroscopic & biologically inert, and resistant to most solvents & reagents.
