Glass microfibre filters, grade GF 6, circles

Recommended filters for environmental analysis and controlling both air and water pollution.Made of 100 % borosilicate glass fibres with bindersGlass fibre filters capture fine particles down to 1 µm from liquids, in air, gases and aerosols with even 0.3 to 0.5 µm being absorbedExtremely low content in alkali-earth metalsChemical stability: It keeps all its properties in contact with acid solutions (except hydrofluoric acid) and basic solutions at moderate concentrationsStabile at temperatures up to 500 °CGravimetrical analysis of organic and inorganic impurities in water and waste water according to DIN 38409 and EN 872 (suspended particles)Measurement of immission, measurement of dust in air and gases, monitoring of the efficiency of filtration and dedusting, monitoring the combustion air of power plants and of the steel and iron industryMeasurement of dust release in workplace and production processes and the purification of compartment airMeasurement of scintillationFiltration time acc. to Gurley
