Product Overview
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. BĆ¼chner funnels are cylindrical with an integral large-pored glass sieve support plate. Without additional filter paper, only coarse filtration is possible. BĆ¼chner funnels can also be used in vacuum filtration. The applied vacuum accelerates the filtration.
Specifications
| Boro 3.3 | Borosilicate glass 3.3 has a very good chemical resistance, virtual inert behavior, a high maximum usage temperature, high light transparency and minimal thermal expansion. Borosilicate glass 3.3 has a linear coefficient of expansion of 3.3 Ć 10ā6 Kā1 at 20 Ā°C. It also conforms to the requirements of a USP/EP/JP Type 1 neutral glass suitable for use by the pharmaceutical industry. The properties of DURANĀ® are specified to ISO 3585 and ASTM-E438 Type 1 Class A. |
