Description
Watch glass dishes, borosilicate glass 3.3, diameter 50 mm are laboratory glassware items used for covering vessels, evaporating small volumes or holding samples during weighing and observation. These concave dishes are produced from borosilicate glass 3.3, a material valued for its chemical resistance and thermal stability in everyday laboratory conditions. The 50 mm diameter format suits smaller beakers and crystallisation work. Supplied in packs of 10 pieces from manufacturer Hecht, the dishes support routine analytical, preparative and educational tasks. Transparent construction permits clear visual monitoring of contents while the glass withstands common reagents and moderate heating. Each pack of ten units provides convenient stock for multiple workstations. The simple, reusable design facilitates cleaning and repeated use in research, quality-control and teaching laboratories. With a compact 50 mm diameter these watch glass dishes integrate easily into standard workflows requiring reliable covering or evaporation surfaces.
This article is part of Watch glasses & crystallising dishes, in Dishes, crucibles & porcelain.

Questions about Watch glass, Made of Boro 3.3, Diameter: 50 mm
What is this article?
Watch glass, Made of Boro 3.3, Diameter: 50 mm is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Watch glasses & crystallising dishes, inside Dishes, crucibles & porcelain, in Labware.
A watch glass is a shallow curved cover or a dish for drying a few grams. A crystallising dish is the flatter, wider dish a solution is left in while a solid comes out. Neither is volumetric. Diameter is the specification.
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.
