Description
Watch glass dishes with 150 mm outer diameter are classic laboratory glassware pieces made from soda-lime glass of the 3rd hydrolytic class. Free from cadmium and lead, they provide an inert, transparent surface for weighing solids, covering beakers, evaporating small liquid volumes or observing precipitates during routine analytical work. Fire-polished edges improve handling safety and reduce chipping risk under repeated use. Packed in units of 10 pieces and also offered in bulk cartons of 30 × 10 pieces, these dishes come from manufacturer Marienfeld and suit everyday tasks in research, quality-control and teaching laboratories. The generous 150 mm working diameter accommodates larger samples while remaining easy to manipulate on the balance or bench. Soda-lime construction of the stated hydrolytic class delivers reliable chemical resistance for aqueous and many organic media encountered in standard procedures. Clear visibility through the glass supports visual inspection of colour changes, crystallisation or drying progress without transferring the sample. These watch glasses integrate smoothly into existing glassware sets and support reproducible sample preparation workflows where heavy-metal-free materials are preferred.
This article is part of Watch glasses & crystallising dishes, in Dishes, crucibles & porcelain.

Questions about Watch glasses 150 mm diameter,
What is this article?
Watch glasses 150 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.
