Description
Hard porcelain crucible lid 79 D/2 with a diameter of 75 mm is a laboratory accessory designed to cover matching porcelain crucibles during heating, ashing and ignition operations. Produced from hard porcelain, the lid supplies a stable cover that assists in retaining sample material and limiting airborne contamination while the crucible undergoes thermal processing. The 79 D/2 type designation defines the size series, and the 75 mm diameter guarantees proper seating on the associated crucibles used in analytical chemistry. Offered as one piece from manufacturer IDL GmbH, this lid forms part of routine porcelainware collections for gravimetric analysis and residue work. The hard porcelain material retains dimensional stability across the temperature cycles typical of muffle furnaces and laboratory hot plates. Uniform lid geometry contributes to reproducible sample containment from the beginning of heating to the end of cooling, allowing laboratories engaged in quantitative inorganic analysis or materials characterisation to maintain consistent handling practices with their existing crucible sets.
This article is part of Crucibles, in Dishes, crucibles & porcelain.

Questions about Crucible lids, porcelain, 79 D/2, Ø 75 mm
What is this article?
Crucible lids, porcelain, 79 D/2, Ø 75 mm is the article on this page. Luminix Health distributes IDL GmbH 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.
