Description
Crucible 79 MF size 1a is a medium-high laboratory melting crucible with a glazed finish and an upper outer diameter of 89 mm. Standing 75 mm high with a nominal volume of 0,3 l (300 ml), it provides a larger working capacity than the size 1 format for melting, ashing, calcining and thermal sample preparation in research, teaching and quality-control laboratories. The medium-high profile eases charging and observation of the contents while remaining compact enough for standard furnace chambers and bench heating setups; the glazed upper zone aids handling and helps limit residue build-up around the rim. Offered in a pack of 10 pieces from manufacturer Haldenwanger, the 79 MF size 1a crucible suits laboratories that run parallel samples or maintain a small stock of identical vessels. Defined outer diameter, height and 0,3 l nominal content support consistent pairing with compatible accessories and reproducible loading across batches. This glazed medium-high crucible is intended for general laboratory high-temperature work where an 89 mm upper opening and approximately 300 ml capacity are specified. Select size 1a when your method calls for the next step up in diameter and volume within the 79 MF medium-high series.

Questions about Crucibles 79 MF size 1a, medium form, glazed, top Ø 89mm, height
What is this article?
Crucibles 79 MF size 1a, medium form, glazed, top Ø 89mm, height 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.
