DURAN® filter crucible 30 ml porosity 4 pack of 10

DURAN® filter crucible, 30 ml, porosity 4. 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. Filter crucibles are filters used for solid-liquid separation by means of vacuum. Filter crucibles have a sintered glass base that serves as the filter medium and does not require additional filter paper. Filter crucibles are also filter funnels. They differ only in the absence of the stem. However, this enables the funnel to be safely placed down and allows further work steps, such as drying the filter residue on the filter in a vacuum desiccator. Special properties and advantages: Filter crucibles have no stem, so that the crucible can be safely placed down and, for example, the collected solid can be dried. They narrow towards the base and reduce potential contamination of the rubber sleeve. Made of DURAN® glass with proven properties, such as chemical resistance and high resistance to thermal shock. Baked-in and therefore permanently durable white printed marking. Application: Qualitative analysis and preparative chemistry, separation and further processing of the filter residue, filtration under reduced pressure, filtering, suitable rubber sleeve and filter support available.
