A shaker is a piece of laboratory equipment used to mix, blend, or to agitate substances in tube(s) or flask(s) by shaking them, which is mainly used in the fields of chemistry and biology. A shaker contains an oscillating board which is used to place the flasks, beakers, test tubes, etc. Although the magnetic stirrer has come to replace the uses of shaker lately, the shaker is still a preferred choice of equipment when dealing with such large volume substances, or simultaneous agitation is required.
Orbital Shaker has a circular shaking motion with a slow speed (25-500 rpm). It is suitable for culturing microbes, washing blots, and general mixing. Some of its characteristics are that they do not create vibrations, and they produce low heat compared to other kinds of shakers, which make it ideal for culturing microbes. Moreover, it can be modified by placing it in an incubator to create an incubator shaker due to its low temperature and vibrations
