Description
Lid Ø 50 mm, porcelain, for crucibles NF is a glazed porcelain cover designed for low-form melting crucibles used in the laboratory. Its 50 mm diameter corresponds to matching NF crucibles, allowing the vessel to be covered during heating, ashing or other sample-preparation operations. Fabricated from porcelain with a glazed surface, the lid provides a smooth finish that is practical for routine handling and cleaning. The item is supplied as a single piece with a net weight of 0,016 kg for laboratories that rely on porcelain crucible systems. This accessory from manufacturer Witeg forms part of the crucible range and is intended for use with low-form melting crucibles where a porcelain lid of the correct diameter is required. In analytical and general chemistry workflows, such lids help keep the crucible opening covered while samples are processed under heat. The glazed porcelain construction supports repeated laboratory use alongside compatible NF crucibles in the same size class.
This article is part of Crucibles, in Dishes, crucibles & porcelain.

Questions about Cover Ø 50 mm porcelain for crucibles LF
What is this article?
Cover Ø 50 mm porcelain for crucibles LF 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.
