DURAN® Buchner Funnel
with Perforated Glass Support Plate
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. Büchner funnels are cylindrical with an integral large-pored glass sieve support plate. Without additional filter paper, only coarse filtration is possible. Büchner funnels can also be used in vacuum filtration. The applied vacuum accelerates the filtration.
- Manufactured from 3.3 expansion borosilicate glass
- The integral perforated glass sieve plate serves as a support for filtration membranes and flter paper
- A range of different funnel sizes are available
- Fired-on, highly durable white print
