Description
Hard porcelain crucible 20 ml 79 MF/7A medium-high form with diameter 40 mm is a laboratory crucible intended for routine thermal sample work. It offers a nominal volume of 0,02 l and an outer diameter of 40 mm, fabricated from porcelain in the medium-high form. The 79 MF/7A model designation identifies this specific hard-porcelain vessel within the series. Supplied as 1 pc from manufacturer IDL GmbH, the crucible suits heating, ashing and ignition steps commonly performed in analytical and materials laboratories. Its compact 40 mm diameter allows convenient placement in standard muffle furnaces, hot plates or over burners while the 20 ml capacity accommodates typical sample loads. Porcelain construction provides the chemical resistance and thermal stability expected of laboratory crucibles. The medium-high profile aids secure handling with tongs and helps retain contents during processing. This size is practical for qualitative analysis, residue determination and educational demonstrations where hard-porcelain ware is preferred. Overall dimensions and volume make the item a versatile addition to general laboratory glassware and porcelain inventories used in research, quality-control and teaching environments.

Questions about Crucible, porcelain, 20 ml 79 MF/7A medium-high form, Ø 40 mm
What is this article?
Crucible, porcelain, 20 ml 79 MF/7A medium-high form, Ø 40 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.
