DURAN Filter Crucible 50 ml Porosity 2 Pack of 10

DURAN® filter crucible, 50 ml, porosity 2 One of the most important separation methods in the laboratory is filtration, which serves to separate or purify substances in 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 a vacuum. Filter funnels have a sintered glass base that serves as the filter medium and does not require any 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 placed down safely and allows further work steps, such as drying the filter residue on the filter in a vacuum desiccator. Special properties and advantages: Filter crucibles do not have a stem, allowing the crucible to be placed down safely and, for example, the collected solid to be dried The crucible tapers towards the base and reduces potential contamination of the rubber collar Made of DURAN® glass with proven properties such as chemical resistance and high resistance to thermal shock Permanently durable white printed marking, fired in Applications: Qualitative analysis and preparative chemistry, separation and further processing of the filter residue, filtration under reduced pressure, filtering, suitable rubber collar and filter adapter available.
