DURAN® filter crucible 30 ml porosity 3 pack of 10 pcs.

DURAN® filter crucible, 30 ml, porosity 2 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 in terms of size and porosity. Filter Nutsche funnels are filters used for solid-liquid separation by means of vacuum. Filter Nutsche funnels have a sintered glass base that serves as the filter medium and does not require additional filter paper. Filter crucibles are also filter Nutsche funnels. They differ only in the absence of the stem. This enables the Nutsche 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 features and benefits: Filter crucibles do not have a stem, so that the crucible can be safely set down and, for example, the collected solid can be dried The crucible narrows 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 Fused-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 adapter available.
