Description
Watch glass dishes, approx. 4 cm are shallow, circular glass vessels commonly employed for covering beakers, evaporating small liquid volumes or holding solid samples during weighing and observation. With a diameter of 40 mm these dishes fit standard small beakers and crystallising dishes while providing a stable, transparent surface. Fabricated from unspecified laboratory glass, they withstand typical heating and chemical exposure encountered in routine analytical and preparative work. Supplied as a single piece from manufacturer Hecht, the watch glasses are suitable for evaporation, drying, sample storage and as lids to minimise contamination or solvent loss. Their simple concave form allows easy stacking and cleaning. These approx. 4 cm watch glass dishes serve as versatile, low-cost consumables in chemistry, pharmaceutical and educational laboratories where clear visibility of the contents and chemical inertness are required.
This article is part of Watch glasses & crystallising dishes, in Dishes, crucibles & porcelain.

Questions about Watch glasses ca. 4 cm
What is this article?
Watch glasses ca. 4 cm 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 Matériel de laboratoire.
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.
