Agitator with heating plate: Why is it fundamental in a biology lab?

Hot plate stirrers are electronic desktop computers that adapt to multiple processes that require temperature and shaking. That is, they are instruments that provide options for simultaneous heating and stirring. This equipment is often used in biology laboratories, as it serves to mix liquids with each other or with powders, for pro produce solutions and different suspensions, due to its versatile design that allows shaking and heating at the same time. Reducing the time of use and reducing the risks of contamination.

Heating plate stirrers are usually used in chemical processes, physical and chemical analysis, pharmaceutical analysis and other fields. Among its most frequent uses we can mention:

  • Chemical analysis drying.
  • Organic synthesis and extraction of compounds.
  • Dialysis and preparation of buffer solutions.
  • Heat treatment, liquid evaporation.
  • Studies related to biochemistry and other compounds.
  • Heat flasks and other glass materials.

Composition of a stirrer with heating plate

As for its characteristics we can say that it is a equipment that has electrical heating elements resistant to corrosion and chemical and mechanical attacks.  It is useful for heating containers with liquids, glass materials, or the contents inside them, in a uniform and controlled manner.

Most heating plate stirrers have a magnetic stirrer that allows the heated liquid to be shaken automatically, this occurs when a small magnet or stirring rod is inserted into it and are preferably used to create solutions or solutions. This type of stirrer usually has a flat surface on which the vessels containing the fluids to be heated or shaken, or both, are placed.  This surface is usually made of materials that are good thermal conductors such as aluminum [Al] or ceramic materials.

An agitator with heating plate has a heating element (an electrical resistance), a control system (on, off, temperature control, stirring control and its respective motor). The motors used in this type of instrument are generally of single-phase induction type, referred to as degraded pole type. Its speed depends on the number of poles and the frequency of the supply voltage.

Gear-driven motorized agitators are preferred because they are quieter, more efficient, and have no moving external parts that can break or wear (other than the simple bar magnet). Due to its small size, the shaking bar is more easily cleaned and sterilized than other shaking devices. Such equipment does not require lubricants that may contaminate the reaction vessel and the product. They can be used inside hermetically sealed containers or systems, without the need for complicated rotating seals.
