Description
The 40mm diameter watch glass has a very good resistance to chemicals. The thermal expansion is small, and the recommended temperature for its use in chemical processes is max. 500° C. In chemistry laboratories it is used to stimulate the evaporation of a liquid. When used as an evaporation surface, the watch glass allows more accurate observation of precipitates or deposited crystals. In order to better highlight the substances left after evaporation, the watch glass can be coated with a film of contrasting color, or it can also be placed on top of a dark surface. Watch bottles can be used to cover laboratory glasses, Erlenmeyer flasks and more. They can also be used as weighing utensils. Composition: borosilicate glass 3.3 Quantity: 10 pieces
