Description
Watch glass dishes with 200 mm diameter 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. They are commonly used for covering beakers, evaporating small volumes, weighing solids or observing reactions. The 200 mm outer diameter provides a generous working surface for medium-scale laboratory tasks. Packed in units of 10 pieces, with bulk packaging available as 10×10 pieces, the items come from manufacturer Marienfeld. The soda-lime glass composition offers good chemical resistance for general laboratory use while remaining economical for high-consumption settings. Fire-polished rims ensure smooth contact with vessels and safe manual handling. These watch glasses support everyday procedures in analytical chemistry, sample preparation and educational laboratories that require reliable, cadmium- and lead-free covering and evaporating dishes of substantial diameter.
This article is part of Watch glasses & crystallising dishes, in Dishes, crucibles & porcelain.

Questions about Watch glasses 200 mm diameter,
What is this article?
Watch glasses 200 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.
