Description
Porcelain lid Ø 50 mm is a glazed laboratory cover designed for high-form melting crucibles (HF). Made from porcelain, it provides a durable, heat-resistant fit that helps shield contents during thermal work and limits contamination from airborne particles. The 50 mm diameter is matched to corresponding high-form porcelain crucibles used in analytical chemistry, ashing, residue preparation and materials testing. A glazed surface supports straightforward cleaning and repeated laboratory use under demanding conditions. This accessory from manufacturer Witeg is offered as a single piece with a net weight of 0,016 kg, giving a compact, practical cover for routine crucible workflows. In heating, cooling or short-term holding steps it closes the vessel opening and complements high-form crucibles in research, quality-control and teaching laboratories. Porcelain construction delivers the chemical and thermal behaviour expected of laboratory ceramics for inorganic samples and high-temperature procedures. Select this glazed Ø 50 mm porcelain lid when equipping or replacing covers for high-form melting crucibles in everyday lab practice.

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