Description
Watch glasses in soda-lime glass with fused edges and a diameter of 40 mm are classic laboratory glassware for covering vessels, holding small samples, and supporting crystallisation or evaporation work on the bench. The fused-edge finish provides a smooth rim that is comfortable to handle during routine weighing, observation, and transfer steps. Each pack contains 10 pc(s) and has a weight of 0,040 kg, making the set convenient for stocking multiple workstations or teaching laboratories. These dishes sit within laboratory glass, vessels, and consumables ranges, specifically among crystallisation dishes and watch glasses used in everyday wet-chemistry practice. Supplied from manufacturer ROTH SELECTION, the 40 mm format suits small beakers, sample cups, and compact setups where a modest cover glass is required. Soda-lime glass construction is appropriate for general non-specialised laboratory tasks involving aqueous media and standard reagents under ambient conditions. The circular profile supports even resting on flat surfaces and straightforward stacking in drawers or trays. Clear glass allows visual inspection of solids, residues, or droplets without removing the cover. The ten-piece unit quantity offers a practical balance between ready availability and economical replenishment for research, quality control, and educational environments.

What is this article?
Watch glasses, soda-lime glass, fused edges, Ø 40 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.
