DURAN Filter Crucible 15 ml Porosity 4 Pack of 10

DURAN® filter crucible, 15 ml, porosity 4 One of the most important separation methods in the laboratory is filtration, which serves to separate or purify different media. For this working method, filters are required that are selected according to the application in terms of 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. 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 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 Permanently durable white printed image that is fired in Application: Qualitative analysis and preparative chemistry, separation and further processing of the filter residue, filtration under reduced pressure, filtering, matching rubber sleeve and filter adapter available.
