Description
Porcelain lid Ø 50 mm for medium-form crucibles is a glazed ceramic cover intended for melting crucibles of medium-high form in laboratory thermal work. With a diameter of 50 mm, it helps limit heat loss and reduce airborne contamination during ashing, ignition and residue handling. Made of porcelain, the lid offers the thermal stability and chemical resistance typical of classic ceramic labware used in analytical and materials procedures. The glazed surface supports smoother seating on matching crucibles and simplifies cleaning after high-temperature cycles. Supplied as one piece with a net weight of 0,016 kg, it suits routine setups where medium-form crucibles are standard. This accessory from manufacturer Witeg integrates easily into chemistry, quality-control and materials-testing workflows that rely on porcelain crucibles for controlled heating of solids and residues. It provides a durable, straightforward cover for everyday furnace and burner work without adding unnecessary complexity to the laboratory setup.
This article is part of Crucibles, in Dishes, crucibles & porcelain.

Questions about Lid Ø 50mm porcelain for crucible medium shape
What is this article?
Lid Ø 50mm porcelain for crucible medium shape 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.
