Questions about stopper CR, redbrown, bottom diameter: 47 mm top diameter: 55 mm height: 40 mm
What is this article?
stopper CR, redbrown, bottom diameter: 47 mm top diameter: 55 mm height: 40 mm is the article on this page. Luminix Health distributes Deutsch & Neumann for laboratory use. It sits in Trays, bowls & tubs, inside Dishes, crucibles & porcelain, in Labware.
A laboratory tray, bowl or tub is an open vessel for holding, staining, drying or carrying many small items at once. Polypropylene trays resist a knock and many aqueous liquids. Porcelain takes heat. The useful numbers are the bottom size and the depth, because that is the working area.
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.
