Grade 423 is particularly recommended for pre-filtration of membrane filters and is also used in combination with Filtech Grade 363 as a highly efficient protective and retentive grade density pre-filter for membrane filters.
FILTECH Glass Fibre filter paper grades contain no binders or other additives that may cause interference in sensitive enzymatic or other chemical reactions. Filtech 100% Binder-Free Glass Fibre Filter Papers are ideal for use in diagnostic applications requiring sample filtration, wicking of fluids and the absorption of reagents or reaction products.
Other applications include: liquid scintillation counting, radioimmunoassay, water and wastewater analysis, TCLP, gravimetric analysis involving ignition of the sample and filtration of hot gases and liquids, environmental and air pollution monitoring and as a membrane pre-filter which will greatly increase the life of the membrane.
