Example of a stirring rod. 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.
Then rubber policeman was also recorded in 1910 edition of J. C. Olsen's textbook of quantitative analysis that states "particles adhering to the glass must be removed by means of a so-called policeman, which is made by inserting the end of a rather thick large-sized glass stirring-rod into a short piece of rubber tubing. The rubber tube should ...
Stirring rods are glass rods used to mix chemicals. Condensers are used to condense vapors by cooling them down and turning them into liquids. [19] Glass retorts are used for distillation by heating, they have a bulb with a long curved spout. [20] Drying pistols are used to free samples from traces of water, or other volatile impurities. [21]
Magnetic stir bars work well in glass vessels commonly used for chemical reactions, as glass does not appreciably affect a magnetic field. The limited size of the bar means that magnetic stirrers can only be used for relatively small experiments, of 4 litres or less. Stir bars also have difficulty in dealing with viscous liquids or thick ...

A temperature-controlled shaker, as used in biochemistry work. A shaker is a piece of laboratory equipment used to mix, blend, or agitate substances in a tube or flask by shaking them. It is mainly used in the fields of chemistry and biology. A shaker contains an oscillating board that is used to place the flasks, beakers, or test tubes.
