Description
Lid for crucibles with 50 mm diameter is a glazed porcelain laboratory cover intended for melting crucibles of matching size during heating, ashing and sample-preparation work. Made of porcelain with a smooth glazed finish, it helps shield contents from airborne contamination and supports more controlled thermal conditions in routine analytical workflows. The 50 mm diameter is selected for crucibles of corresponding dimensions so that the lid sits correctly during melting and high-temperature handling. Packed in cartons of five pieces from manufacturer Marienfeld, the set suits laboratories that need a practical stock of matching lids for daily use. Glazed porcelain offers a durable, wipe-clean surface suited to repeated laboratory cycles and straightforward cleaning between runs. These lids belong to standard labware for chemistry, materials characterisation and quality-control environments where melting crucibles are used. They integrate easily into existing crucible sets and storage systems without special adapters. The five-piece carton format supports organised replenishment and shared bench or store-room supply. Overall, the product provides a simple, material-matched cover for porcelain melting crucibles in professional laboratory practice.

Questions about Lids for crucibles of 50 mm diameter,
What is this article?
Lids for crucibles of 50 mm diameter, is the article on this page. Luminix Health distributes Marienfeld 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.
