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.

• Vacuum resistant due to the heavy wall thickness
• These filtering flasks fulfil the regulations of the equipment and product safety regulations
• Fired-on, highly durable white print
• Erlenmeyer shape
