Description
Porcelain crucible 21 ml, low form, glazed is a laboratory melting crucible intended for thermal processing and sample preparation. Fabricated from porcelain with a glazed finish, it provides 21 ml capacity, a diameter of 45 mm and a height of 28 mm in the low-form design commonly chosen for heating, drying and ashing work. The article is manufactured to DIN 12904, supporting consistent dimensions for routine laboratory use. The glazed surface aids clean handling and residue recovery after ignition or fusion steps. This crucible from manufacturer Witeg is supplied as one piece and suits analytical chemistry, materials characterisation and general lab practice where porcelain ware is specified. Low-form geometry offers a stable base and easy access for stirring or transfer, while the 21 ml volume matches moderate sample loads on balances and in muffle furnaces. Net weight is 0,016 kg. Typical applications include drying, calcination, ash determination and related thermal procedures that require durable glazed porcelain crucibles in the low-form style.

Questions about Crucibles 21 ml porcelain low form glazed
What is this article?
Crucibles 21 ml porcelain low form glazed 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.
