DURAN filter crucible 15 ml porosity 1 pack of 10

DURAN® filter crucible, 15 ml, porosity 1 One of the most important separation methods in the laboratory is filtration, which is used to separate or purify different media. For this working method, filters are required that are selected according to the application with regard to size and porosity. Filter funnels are filters used for solid-liquid separation by means of vacuum. Filter funnels have a glass-sintered 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. This enables the funnel to be safely set 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 set down and, for example, the collected solid can be dried The crucible tapers towards the base and reduces potential contamination of the rubber sleeve Made of DURAN® glass with proven properties such as chemical resistance and high resistance to thermal shock Fired-in and therefore permanently durable white printed image Application: Qualitative analysis and preparative chemistry, separation and further processing of the filter residue, filtration under reduced pressure, filtering, matching rubber sleeve and filter stem available.
