Description
Evaporating dishes with a diameter of 90 mm offer an ample shallow surface for evaporating solvents, concentrating solutions, and drying laboratory residues. Made from soda glass in traditional watch-glass form, they feature thin walls that respond promptly to gentle heating and a fused rim that creates a smooth, chip-resistant edge for safe handling. The broad open profile maximises the liquid–air interface, supporting efficient evaporation under mild thermal conditions or at ambient temperature while allowing continuous visual control of the sample. Each dish has a net weight of 0,03 kg and is packed in units of 10 pieces for everyday laboratory supply. These evaporating dishes from manufacturer Witeg serve teaching, quality-control, and research environments where aqueous media and many mild organic solvents are processed. Typical tasks include sample concentration, drying of precipitates, crystallisation steps, and intermediate storage before analytical weighing or further work-up. The 90 mm soda-glass design provides useful capacity without excess bulk and integrates readily with standard hotplates, desiccators, and bench organisation systems used in general laboratory practice.
This article is part of Evaporating dishes, in Dishes, crucibles & porcelain.

Questions about Evaporating dishes Ø: 90 mm
What is this article?
Evaporating dishes Ø: 90 mm is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Evaporating dishes, inside Dishes, crucibles & porcelain, in Labware.
An evaporating dish is a shallow porcelain or glass dish used to drive off a liquid over heat. The flat form gives surface area. Porcelain takes a higher heat than borosilicate. It is not a crucible and it is not a volumetric vessel.
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.
