Description
Aluminium oxide crucible, high form, 250 ml is an unglazed laboratory crucible manufactured from aluminium oxide 99,7 % for demanding thermal applications. Temperature resistant up to 1750 °C, the high-form vessel offers chemical inertness and dimensional stability during ashing, calcination, melt work and other high-temperature preparation steps. The 250 ml working volume suits laboratories that need a larger ceramic crucible for furnace-based analytical or materials workflows. Pack size is one piece with a net weight of 0,330 kg; a lid is not included, allowing free selection of covers according to protocol. This crucible from manufacturer Labbox belongs to the HDN ceramics product type and is designed for repeated use in muffle furnaces and controlled heating environments. The unglazed alumina body provides direct contact with the ceramic matrix without glaze coatings that may be unsuitable at elevated temperature. The high-form geometry aids handling with tongs and supports efficient heat transfer throughout thermal cycles in research and quality-control settings.

Questions about Alumina crucible high form, 250 ml
What is this article?
Alumina crucible high form, 250 ml is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Crucibles, inside Dishes, crucibles & porcelain, in Matériel de laboratoire.
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.
