A biological laboratory relies on several lab equipment to carry out smooth and successful studies on a daily basis. These equipment facilitate various activities such as creation of a sterile work environment, accurate measurements, temperature maintenance etc. One such category of equipments include refrigerators and freezers. Since biological requires precision in terms of the experimental environment, it is essential to ensure accurate temperature control. Refrigerators and freezers play a vital role in this aspect. These instruments allow the storage of reagents and samples over an extended period of time. Refrigerators are widely used for the storage of enzymes, buffers, dyes etc and prevent them from temperature-associated degradation. Freezers maintain temperatures below 0 and are used for the storage of cell cultures and in blood banks to store samples in a frozen from over a span of several days. These refrigerators and freezers are equipped with a robust temperature monitor and control system that allows maintenance of a constant desired temperature.
