Description
Crucible 79 MF size 7a is a medium-high form melting crucible with a glazed upper section, an outer diameter of 40 mm and a height of 32 mm. The nominal volume is 20 ml (0,02 l), offering a larger working capacity than smaller 79 MF sizes while retaining the same medium-high geometry. The 40 mm upper opening and 32 mm height give a practical balance between fill volume and vessel stability for laboratory melting work. Upper glazing helps keep the rim area easier to handle and clean during repeated thermal cycles. This 79 MF size 7a crucible from manufacturer Haldenwanger comes in a pack of 100 pieces, supporting consistent use across multiple samples or parallel preparations. Clearly stated dimensions—outer diameter 40 mm, height 32 mm and content 20 ml—simplify selection against holders, furnace space and protocol requirements. As a glazed medium-high melting crucible of size 7a in the 79 MF range, it is intended for general laboratory melting applications that call for a 40 mm upper diameter and a 20 ml nominal capacity.

Questions about Crucibles 79 MF size 7a, medium form, glazed, top Ø 40mm, height 32mm, capacity
What is this article?
Crucibles 79 MF size 7a, medium form, glazed, top Ø 40mm, height 32mm, capacity 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.
