DURAN® Buechner Funnel, 70 mL
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.
Features and Benefits:

• The slit sieve support serves as a carrier for membrane and paper filters.
• From DURAN® glass with its good thermal shock and chemical resistance
• Fired-on, highly durable white print

Application: Qualitative inorganic analysis and preparative chemistry, Coarse filtration (without additional filter paper), Filtration at reduced pressure, Filtering
