Description
Gooch filter crucible 30 ml P4 is a laboratory glass filtration vessel designed for solid-liquid separation and subsequent handling of retained solids. With a nominal capacity of 30 ml and porosity grade P4, the crucible provides a defined pore structure suited to retaining fine precipitates while permitting filtrate passage under suction. The single-piece unit has a net weight of 0,031 kg and a matching gross weight of 0,031 kg, making it convenient for analytical balances and gravimetric workflows. Produced by manufacturer Witeg, this Gooch-style filter crucible integrates readily into standard filtration assemblies used in quantitative analysis, sample preparation and quality-control laboratories. Its compact form supports drying, ignition or weighing steps after filtration without transfer losses. The P4 designation indicates a controlled porosity appropriate for many routine laboratory separations. Originating from Germany (Baden-Württemberg), the crucible is intended for everyday analytical practice where reusable glass filterware of defined volume and porosity is required. Laboratories performing precipitate isolation, residue determination or related gravimetric procedures can employ this 30 ml P4 Gooch filter crucible as a reliable working vessel.

Questions about Crucibles with sintered disc Gooch 30 ml P4
What is this article?
Crucibles with sintered disc Gooch 30 ml P4 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Crucibles, inside Dishes, crucibles & porcelain, in Labware.
A crucible holds a sample in a furnace or over a flame, at temperatures that would soften a borosilicate beaker. Porcelain, platinum and glazed ceramic are different articles. The form, tall or wide, decides how fast a sample dries or ashes.
A dish is an open vessel for drying, evaporating or holding a solid. Porcelain and glazed ceramic take a higher temperature than borosilicate glass, which is why a crucible, not a beaker, goes into a furnace. A watch glass covers, or holds a small amount for drying. A mortar is for grinding. The temperature and the chemical, not the shape alone, choose the material. Laboratory ware of this family is listed under ISO laboratory ware.
