DURAN Büchner funnel 70 ml Ø48 mm for Ø45 mm filter

DURAN® Büchner funnel, 70 ml One of the most important separation methods in the laboratory is filtration, which is used to separate or purify different media. This working method requires filters selected according to the application in terms of 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 benefits: The slotted sieve nutsche 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 Fused-in and therefore permanently durable white printed image Application: Qualitative analysis and preparative chemistry, coarse filtration (without additional filter paper), filtration under reduced pressure, filtering
