Description
Crucible lid 79 D size 7a is a laboratory crucible cover matched to crucibles with a diameter of 40 mm. As part of the 79 D series, size 7a identifies this lid for pairing with the corresponding 40 mm crucible format used in everyday lab practice. A correctly sized lid is essential whenever crucibles must be covered during sample handling, thermal steps, or intermediate storage on the bench. The product is packed as 50 pieces, which suits facilities that stock several crucible sizes or replace lids regularly without mixing diameters. Clear marking by series, size 7a, and the 40 mm fit simplifies ordering and inventory control next to matching crucible bodies. This crucible lid from manufacturer Haldenwanger belongs to the broader range of laboratory materials used in analytical, process, and educational laboratories. Selecting the 79 D size 7a lid ensures dimensional compatibility with Ø 40 mm crucibles and keeps accessory sets uniform across workstations. Use it wherever a dedicated cover for 40 mm crucibles is required as a standard consumable laboratory component.

Questions about Crucibles lids 79 D, size 7a, suitable for crucible Ø 40mm
What is this article?
Crucibles lids 79 D, size 7a, suitable for crucible Ø 40mm is the article on this page. Luminix Health distributes Haldenwanger 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.
