Qualitative Quartz microfibre filters, QFH, round filters
Recommended filters for atmospheric pollution control and for particles determination at high temperatures.Filters made of pure quartz microfibre (SiO2), free of binding elements or additivesExtremely low content in alkali-earth metalsDetermination of suspended particles (SPM and TSP) in ambient air acc. to the directive of the US EPA (Environmental Protection Agency) and the EN 23210Retention: Excellent retention of very fine particles through the adsorption mechanisms of quartz fibresChemical stability: excellent stability with hardly any loss of filter-material due to chemical reactions under extreme conditions with acid gases (HCl, SO2, SO3, H2SO4, NO and NO3)Resistance to chemical reagents: excellent resistance to solvents, acids (except HF) and alkaline substancesStability at high temperatures: higher resistance than glass microfiber, up to 1000 °CWeight: 85 g/m2Thickness: 0.45 mmFurther sizes on request.

Quartz microfibre filters, grade QM-A, round filters
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.Manufactured from quartz microfibre to withstand high temperatures. Can be used up to 500 °C.
