Glass Microfiber Filters with Binder 含有黏合剂的玻璃微纤维滤纸 Grade GF 6: Inorganic binder
Good retention for very fine particles. This filter is used in water pollution applications, for removing protein from difficult-to-filter beers, for determination of chlorophyll and phytoplankton residues, for the determination of filterable substances and the residue on ignition (dry weight), for the analysis of aggressive media (e.g., acidic gases), for scintillation measurements and for determination of the elemental iron content in the presence of iron oxides.
Grade GF 8: Inorganic binder
This glass fiber filter is used in the filtration of coarse particles. Frequently used in environmental analysis, in the determination of PCB, DDE, DDT, furans and dioxins in the air; pollution measurements in industrial, urban and populated areas, cement factories, iron and steel industry, dust measurements at the workplace, determination of the dust fraction in technical gases, and testing the effectiveness of dust-collecting.
Grade GF 9: Inorganic binder
Used in similar applications to GF 8.
Grade GF 10: Organic binder
This filter with extreme mechanical stability and temperature resistant up to 180°C is used as a weighing aid for infrared weighing and as a roll filter in automatic air filtration units.
Grade GF 92: Inorganic binder
This filter is used as a membrane prefilter in applications such as the determination of crop protection agent residues by GC or HPLC, in cold sludge determination of beer, in soot separation before gas analyzers and as roll filters in automatic air filtration units.
Grade GF 3362: Inorganic binder
Thicker and slightly denser than GF 9, for the fast filtration of large amounts of particles.
