An evaporating dish is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids, [a] and sometimes to their melting point.Evaporating dishes are used to evaporate excess solvents – most commonly water – to produce a concentrated solution or a solid precipitate of the dissolved substance.
Unlike wire gauze, which primarily supports glassware such as beakers, flasks, or evaporating dishes and provides indirect heat transfer to the glassware, the pipeclay triangle normally supports a crucible and allows the flame to heat the crucible directly. The triangular shape allows rounded crucibles of various sizes to rest in a stable way.
Glass evaporating dishes, such as watch glasses, are primarily used as an evaporating surface (though they may be used to cover a beaker.) The Petri dish is a flat dish filled with a nutritious gelatin that allows for microorganisms to quickly grow, its named after its inventor Julius Petri in the 1880s.
Norbert Rillieux (March 17, 1806 – October 8, 1894) was a Louisiana Creole inventor who was widely considered one of the earliest chemical engineers and noted for his pioneering invention of the multiple-effect evaporator. This invention was an important development in the growth of the sugar industry.
Crucible tongs are scissors-like tools with a pair of attached arms that curve outward near the ends to form a rounded gripping area that allows users to safely grasp crucibles, flasks, evaporating dishes, or small beakers. [1] They are made of durable metals—stainless steel, brass, or nickel, for example—that can withstand high ...
Nils Wallerius (1 January 1706 – 16 August 1764) was a Swedish physicist, philosopher and theologian. He was one of the first scientists to investigate and document the characteristics of evaporation using modern scientific methods.
Evaporating flasks (for rotary evaporator) centered, pear shaped, with socket or with flange. Powder flasks, for drying of powdered substances, pear shaped, with socket; Retorts are simplified distillation apparatuses, with long, down turned necks, and round bases. They have largely been replaced by condensers.
Lloyd Groff Copeman (December 28, 1881 – July 5, 1956) [1] was an American inventor who devised the first electric stove and the flexible rubber ice cube tray, among other products. He had nearly 700 patents to his name, and he claimed that he could walk into any store and find one of his inventions.
