FILTER PAPER, ROUND GF 9

Glass microfibre filters have a fast filtration and a high loading capacity and particle retention rate. Manufactured without chemical binder from high grade borosilicate glass. (Exception: GF6, GF9). They are suitable for gravity or low suction filtration. Filtration speeds generally very much higher than conventional cellulose papers. Efficient retention of micron size particles. Must be used flat. Ideal for use in flat perforated plate Buchner type funnels (not sintered glass models). Can be used up to 500 °C.

Glass fibre filters are made of 100% borosilicate glass fibres with an inorganic binder. Temperature resistant up to 500 °C. Glass fibre filters are chemically resistant except against hydrofluoric acids and highly concentrated alkalis. Filtration speed to Herzberg.
Application:

• Gas-/air-monitoring
• Water and waste water determination
