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. Filter chutes are filters that are used for solid-liquid separation by means of vacuum. Filter crucibles have a Glassinter bottom which serves as a filter medium and does not require any further filter paper. Filter crucibles are also filter crucibles. They differ only in the absence of the stem. However, this allows a safe positioning of the filter crucible and further working steps such as the drying of the filter residue on the filter in a vacuum desiccator.
