The types of vessels include glass or plastic bottles, flasks, tubes, and microplates. Shakers are categorized by the type of movement used, which can be orbital (circular), reciprocating, vibrating, rocking, waving (gyrating), rotating (rotisserie), or wrist-action. Typically a shaker will have analog or digital controls for setting the speed and sometimes also the degree of movement. Some shakers have the ability to incubate or refrigerate samples during shaking. Shakers are used in a variety of laboratory procedures, including hemolysis, preparation of emulsions and suspensions, staining, and cell cultivation.Heidolph Instruments manufactures laboratory equipment such as evaporators, peristaltic pumps, and hot plate stirrers.
