Glass fibre filters / quartz fibre filters
Glass fibre filters allow a fast filtration and simultaneously a very high particle retention. They are manufactured from borosilicate
glass fibres and are chemically resistant towards most organic and inorganic solvents (except HF). For the analysis of air-borne
particles we recommend the quartz fibre filtersMNQF-10 which feature an extremely low content of metal traces.
Glass Microfibre Filters
Filtration Products
Extraction thimbles are often used for holding solid materials,
fromwhich certain substances are to be eluted (extracted) with
a suitable solvent. Additionally, extraction thimbles are used in
the fields of air and waste gas analysis for collecting solid
particles (dust).
