One of the most important separation methods in the laboratory environment is filtration, which is used to separate or clean different media. For this working method, filters are required which are selected according to the application with regard to size and porosity. The filter funnel head consisting of the filter head, sealing ring, glass filter disk and funnel can be dismantled into its individual parts and each individual component can be replaced or varied in order to adapt the filter to the application. The three unit sizes combined with four filter plates of different porosities each create 12 different filter options.
