Glass fibre filters are made of 100 % borosilicate glass fibres with inorganic binder. They are mechanically stable, this makes the handling easier. They can be used up to + 500 °C. Glass fibre filters are resistant against aggressive chemicals except hydrofluoric acids and highly concentrated bases. They are known for their fast filtration time (compared to other media) with excellent retention rates, even of very fine particles from aqueous and gases.Applications: - Gas / air monitoring.- Water and waste water determination.
