Introduction introduction Filter papers quantitative  analysis Extraction thimbles qualitative analysis Membranes glass fibre filters Test papers technical applications Filter papers Raw materials and manufacture © Javier Soto / Fotolia.de For production of the high quality MN filter papers we use cotton linters, refined pulp with a high level of α-cellulose as well as glass fibres. Cotton linters are short-fibred seed hairs from cotton seeds, which cannot be used for textile purposes, but which are highly suitable for the manufacture of soft and absorbent filter papers. In addition to...

Introduction introduction Filter papers Extraction thimbles qualitative analysis Membranes glass fibre filters Test papers technical applications Wet-strengthened filter papers for quantitative analysis These wet-strengthened hard filter papers are manufactured from refined pulp and linters and have a low ash content of < 0.01 %. They are often used for quantitative routine procedures and for analytical gravimetric applications. Due to their high mechanical strength in wet condition they are particularly suited for applications, where the residue is removed from the filter e.g. with a...

Introduction introduction Filter papers Extraction thimbles qualitative analysis Membranes glass fibre filters Test papers technical applications Wet-strengthened filter papers for qualitative applications Wet-strengthened analytical filter papers are manufactured from refined pulp and linters and feature a content of α-cellulose of more than 95 %. The smooth surface of these papers allows fibre-free filtration. They feature a high wet strength and can also be used in the filtration of strongly alkaline or strongly acidic solutions. Due to their high mechanical strength in wet condition...

Filter papers Introduction introduction quantitative  analysis Extraction thimbles qualitative analysis Membranes glass fibre filters Test papers technical applications 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 filters MN QF-10 which feature an extremely low content of metal traces....
