Quartz microfibre filters circles 47mm grade QM-A Pack of 100 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 Wide range of applications including: -retention of fine analytical precipitates -retention of biochemical gelatinous precipitates -water/air pollution analyses -as prefilters for membranes -scintillation counting -radioimmunoassay. Manufactured from quartz microfibre to withstand high temperatures. Can be used up to 500°C.
