DURAN Büchner funnel 220 ml Ø 73 mm for Ø 70 mm filter

DURAN® Büchner funnel, 220 ml. One of the most important separation methods in the laboratory environment is filtration, which serves to separate or purify substances from different media. For this working method, filters are required that are selected according to the application with regard to size and porosity. Büchner funnels are cylinders with an integrated large-pore sieve plate. Without additional filter paper, only coarse filtration is possible. Büchner funnels can also be used in vacuum filtration. The applied vacuum accelerates filtration. Special properties and advantages: The slotted sieve Büchner funnel serves as a support for membrane and paper filters Made of DURAN® glass with proven properties, such as chemical resistance and high resistance to thermal shock Permanently durable white printed image, baked in and therefore long-lasting Application: Qualitative analysis and preparative chemistry, coarse filtration (without additional filter paper), filtration under reduced pressure, filtering
