Description
Watch glass dishes with an outer diameter of 120 mm are laboratory glassware items manufactured from soda-lime glass of the 3rd hydrolytic class. Free from cadmium and lead, the dishes feature fire-polished edges that improve handling safety and reduce the risk of chipping. These concave dishes are widely used for evaporating small liquid volumes, covering beakers to protect contents from dust, weighing hygroscopic substances, or observing crystallisation processes. The transparent surface permits clear visual inspection of samples throughout experimental procedures. Supplied in packs of 10 pieces from manufacturer Marienfeld, with bulk packaging referenced as 30 × 10 pieces, the 120 mm watch glasses provide a durable and chemically stable platform for everyday work in chemistry, biology and quality-control laboratories.
This article is part of Watch glasses & crystallising dishes, in Dishes, crucibles & porcelain.

Questions about Watch glasses 120 mm diameter,
What is this article?
Watch glasses 120 mm diameter, is the article on this page. Luminix Health distributes Marienfeld 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.
