Laboratory glassware may be made from several types of glass, each with different capabilities and used for different purposes. Borosilicate glass is a type of transparent glass that is composed of boron oxide and silica, its main feature is a low coefficient of thermal expansion making it more resistant to thermal shock than most other glasses ...

Laboratory flasks have traditionally been made of glass, but can also be made of plastic. At the opening(s) at top of the neck of some glass flasks such as round-bottom flasks , retorts , or sometimes volumetric flasks , there are outer (or female) tapered (conical) ground glass joints .
Scientific glassblowing is a specialty field of lampworking used in industry, science, art and design used in research and production. Scientific glassblowing has been used in chemical, pharmaceutical, electronic and physics research including Galileo's thermometer, Thomas Edison's light bulb, and vacuum tubes used in early radio, TV and computers.
A glass stirring rod, glass rod, stirring rod or stir rod is a piece of laboratory equipment used to mix chemicals. They are usually made of solid glass, about the thickness and slightly longer than a drinking straw , [ clarification needed ] with rounded ends.
A Florence flask has a round body, a long neck, and often a flat bottom. It is designed for uniform heating, boiling, distillation and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use. They are often made of borosilicate glass for heat and chemical resistance
The Marcusson apparatus, Dean-Stark apparatus, Dean–Stark receiver, distilling trap, or Dean–Stark Head is a piece of laboratory glassware used in synthetic chemistry to collect water [1] [2] (or occasionally other liquid) from a reactor.
