Description
Watch glasses in soda-lime glass with fused edges and a diameter of 200 mm are versatile laboratory glassware for covering beakers, evaporating dishes and other open vessels during sample handling, short evaporations and temporary storage. The shallow curved profile also supports weighing of solids, visual observation of reactions and simple crystallisation work on the bench. Fused rims help limit chipping and give a smoother seating surface when the glass rests on flasks or dishes. Offered as a pack of 10 pieces with a total weight of 2,340 kg, these watch glasses from manufacturer ROTH SELECTION suit routine chemistry, teaching laboratories and general analytical workflows where clear, economical cover glass is required. Soda-lime glass provides good optical clarity for inspecting contents while remaining practical for everyday consumable use. Typical applications include dust protection during evaporations, temporary lids for crystallising solutions and small platforms for drying or mixing tasks. The 200 mm diameter is sized for larger vessels common in preparative and educational settings, fitting naturally among crystallisation dishes and watch glasses in laboratory glass, vessels and consumables assortments.

What is this article?
Watch glasses, soda-lime glass, fused edges, Ø 200 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.
