DURAN® slotted sieve funnels,1000 ml (Buechner funnel)

DURAN® Büchner funnel, 1000 ml One of the most important separation methods in the laboratory environment is filtration and is used for substance separation or purification of different media. Filters are required for this working method and are selected according to the application in terms of size and porosity. Buechner funnels are cylinders with an incorporated large-pored sieve plate. Without an additional filter paper, only coarse filtration is possible. Buechner funnels can also be used in vacuum filtration. The vacuum applied accelerates the filtration. Special features and advantages: The slotted sieve funnel serves as a carrier for membrane and paper filters Made of DURAN® glass with the proven properties, such as chemical resistance and high thermal shock resistance Burnt-in and therefore permanently durable white printed image Application: Qualitative analysis and preparative chemistry, coarse filtration (without additional filter paper), filtration at reduced pressure, filtration
