What is a lab magnetic stirrer?


  • A lab magnetic stirrer is a device that is used in biological laboratories for example microbiology labs. Due to its characteristics, it is also known as a magnetic mixture.
  • The main task of a magnetic stirrer is to cause a stir bar absorbed in a liquid to spin quickly.
  • Biological laboratories and microbiological laboratories make use of magnetic mixer stirrer as it is small in size and easy to move it from one place to another.
  • Even, this device is easily cleansed and sterilized than any other laboratory equipment.
  • When it comes to comparing magnetic mixture to motorized stirrer, more often researchers prefer magnetic stirrer because of its features and quality usage.
  • Moreover, it saves lot of times because it gives result within no time. This helps researchers provide necessary details with proper information and analysis.
  • Though there are drawbacks of magnetic mixture, still lab technicians use it because of its authenticity and perfection in any report and research.
  • One of the negative aspects of this laboratory equipment is its limited size of stirring bar.
  • With its limitation, it can be used for small experiments comparing to some other lab devices. While for the larger volumes, other mechanical stirring devices are used in order to get expected results.
  • Apart from this, magnetic stirrer is mostly used in chemistry laboratories as it is light in weight and efficient in delivering diagnosis or reports.
  • Without any kind of lubrication, it works smoothly. And depending upon its usage, researchers or technicians can place it inside the closed vessels or systems and it doesn’t require any complicated rotary seals.
  • In some usages, it requires hot plates or other equipment for heating the liquid so that an authentic report can be generated without any inadequacy.
  • Thus, one can get maximum benefits out of magnetic stirrers or mixtures while using them in chemistry laboratory or microbiology laboratory.
