A scientist placing samples into a negative 80 degree freezer. In contrast to short term sample storage at +4 to −20 °C (39 to −4 °F) by using standard refrigerators or freezers, many molecular biology or life science laboratories need long-term cryopreservation (including "cold chain" and/or "colder chain" infrastructures) for biological samples like DNA, RNA, proteins, cell extracts ...
Room temperature storage of samples is sometimes used, and was developed in response to perceived disadvantages of low-temperature storage, such as costs and potential for freezer failure. [21] Current systems are small and are capable of storing nearly 40,000 samples in about one tenth of the space required by a −80 °C (−112 °F) freezer.
A liquid (glycol based) chiller with an air cooled condenser on the rooftop of a medium size commercial building. In air conditioning systems, chilled coolant, usually chilled water mixed with ethylene glycol, from a chiller in an air conditioning or cooling plant is typically distributed to heat exchangers, or coils, in air handlers or other types of terminal devices which cool the air in ...
