Beschrijving
Watch glass dishes with 100 mm diameter are versatile laboratory vessels made from soda-lime glass of the 3rd hydrolytic class. Free from cadmium and lead, they feature fire-polished edges that improve handling safety during weighing, evaporation, covering of beakers or visual inspection of samples. Supplied in packs of 10 pieces from manufacturer Marienfeld, these transparent dishes integrate readily into routine analytical, preparative and educational workflows in chemistry and biology laboratories. The 100 mm outer diameter provides a practical working surface for drying residues, observing precipitates or holding small quantities of solids and liquids. Bulk outer cartons containing 30 packs of 10 pieces support economical stock management in teaching labs and high-throughput environments. The inert glass construction allows clear optical monitoring while offering adequate resistance to typical laboratory reagents and mild thermal stress. These watch glasses serve as reliable, contaminant-free tools for everyday sample preparation, temporary storage and observation tasks where clean, reusable glass surfaces are required.

Questions about Watch glasses 100 mm diameter,
What is this article?
Watch glasses 100 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 Labmateriaal.
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.
