LLG-Glass microfibre filters, filter circles

Glass microfibre filters have a fast filtration and a high loading capacity and particle retention rate. Manufactured from high grade borosilicate glass. 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. Filtration velocity acc. to Herzberg.Wide range of applications including:Retention of fine analytical precipitatesRetention of biochemical gelatinous precipitatesWater/air pollution analysesAs prefilters for membranesScintillation countingRadioimmunoassay
