DURAN® Gooch Filter Crucible manufactured by DWK Life Science is made from 3.3. expansion borosilicate glass. This Gooch Filter Crucible comes with a glass sintered bottom which serves as a filter medium, making it suitable for solid-liquid separation by means of vacuum without additional filter paper. The flat bottom of Gooch filter crucible allows the crucible to sit safely on a flat surface, allowing further working steps such as the drying of the filter residue in the crucible in a vacuum desiccator.
