Laboratory Refrigerators are typically designed and developed to store critical materials over extended periods of time. The temperatures of these refrigerators is well maintained and kept constant at all the times so that samples which are kept in it can be preserved in a moderate and stable environment. Laboratory Refrigerators work most efficiently at the time when the temperature of the room wherein they are kept is also maintained. Eventually, very high temperatures also hamper the working performance of the refrigerator, and therefore it is advisable to keep them inside rooms that have a temperature going up to a maximum of 45 degrees C. Although, in high temperature room the pressure on the freezer compressor is quite higher.
