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. Buechner funnels are cylinders with an integrated large-pored sieve plate. Without additional filter paper, only coarse filtration is possible. Buechner funnels can also be used in vacuum filtration. The applied vacuum accelerates the filtration. The filtering flask is a thick-walled vessel which is used as a collecting vessel for the filtrate during filtration.

• Provision of filtration flasks with a socket has not only made work in preparation and analytical laboratories easier and simpler, but has also reduced the risk of accidents
• Vacuum resistant due to the heavy wall thickness
• Fired-on, highly durable white print
• Bottle shape
