DURAN® filter crucible 8 ml, porosity 4, pack of 10

DURAN® filter crucible, 8 ml, porosity 4 One of the most important separation methods in the laboratory is filtration, which is used to separate or purify substances in different media. For this working method, filters 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 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 narrowing towards the base reduces potential contamination of the rubber sleeve Made of DURAN® glass with proven properties such as chemical resistance and high resistance to temperature changes Fired-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, matching rubber sleeve and filter support available.
