Description
Watch glasses in soda-lime glass with fused edges and a diameter of 50 mm serve as versatile laboratory covers and shallow dishes for sample handling, short evaporations, and crystallisation steps. The fused edges create a smooth circumference that is easy to grip and place during weighing, observation, and transfer operations. Packs contain 10 pc(s) at a weight of 0,100 kg, which is practical for equipping several benches or classroom stations at once. They form part of laboratory glass, vessels, and consumables assortments dedicated to crystallisation dishes and watch glasses in general wet-chemistry work. This 50 mm variant from manufacturer ROTH SELECTION matches mid-sized beakers and sample containers where a slightly larger cover glass is preferred. Soda-lime glass is suitable for routine laboratory use with aqueous solutions and common reagents under normal ambient conditions. The circular shape rests stably on flat surfaces and stores efficiently in trays or drawers. Optical clarity of the glass supports direct visual checks of solids, films, or liquid residues without lifting the piece. A ten-piece pack keeps sufficient stock on hand for research groups, quality-control labs, and teaching facilities that rely on standard watch glasses day to day.
This article belongs on Watch glasses & crystallising dishes, in Dishes, crucibles & porcelain.

What is this article?
Watch glasses, soda-lime glass, fused edges, Ø 50 mm, 10 unit(s) is the article on this page. Luminix Health distributes Carl Roth 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.
