What is a beaker used for in science?
Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations. Laboratory Burners are sources of heat.
What is a stirrer in physics?
A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (or flea) immersed in a liquid to spin very quickly, thus stirring it.
What is a test tube used for in science?
The test tube is one of the most commonly used pieces of laboratory ware. Test tubes are the perfect shape and size to hold small amounts of substances, usually liquid, which are then manipulated in some way, such as being placed over the flame of a Bunsen burner.

A laboratory tripod is a three-legged platform used to support flasks and beakers. … Often a wire gauze is placed on top of the tripod to provide a flat base for glassware. Tripods are generally tall enough for a bunsen burner to be placed underneath.
Why glass rod is used in decantation?
Use of glass rod during decantation of a liquid ensures that the liquid to be poured does not stick to the walls of the glassware and is directly poured into it without any spillage and spatter. It is useful during pouring of reactive chemicals.
