Munktell GLASS FIBRE PRE-FILTERS
Generally, glass fibre filters are very open-structured and have a large available surface area and filter depth.
Other than membranes, they offer a rather high dirt holding capacity and are therefore often used in the filtration of difficult-to-filter liquids. They are placed on top of the membrane filter to enhance its service life.
We offer three different grades – with and without binder. Filters without binder are recommended for analytical and gravimetrical analysis as well as for the pre-filtration of relatively clean solutions such as tissue culture media.
