Syringe Filters

Syringe filters are used to clean up samples either direct (e.g. water samples from nature) or after sample preparation of biological samples or pharmaceutical substances to prevent particle pollution on the HPLC column or in other sensitive applications. We supply all types of filtering membranes and porosities as well as diameters from 4 to 30 mm. You can also have 47 mm membranes for filtering bigger volumes in a funnel. A porosity of 0.45µm is normally enough for analytical work while you will need 0.20 µm to filtrate away eventual bacterias.
