One of the most important separation methods in the laboratory environment is filtration, which is suitable for the separation or purification of different media. For this working method, filters are required which are selected according to the application with regard to size and porosity. Due to their size, microfilter candles are used for the filtration of very small quantities. This filtration is possible from a liquid or a carrier gas. The micro filter candle is suitable for the extraction of supernatant solutions but also for the separation of solids from a carrier gas.
