Ultra Low Temperature Freezer Principle

This will be referred to as ultra low temperatures.

Ultra low temperature freezer principle.

Low temperature refrigeration is defined as those applications requiring evaporator temperatures in the range of 20 of down to 250 of. Ultra low temperature ult freezers in 40 c and 86 c models feature a microprocessor led touchscreen display lockable doors and a host of features for superior sample storage. The ult freezer safeguards biological samples by keeping them at very low temperatures. The most common temperature for storing materials in ultra low freezers is 80 c.

2 86 degree ultra low temperature freezer ult freezer widely used in biological products chemical. Unfortunately freezer warm ups and compressor failures are not uncommon events. The operating temperature can range from 45 c to 89 c several features make an ultra low freezer an extremely reliable solution for laboratory research. Generally ultra low temperature freezer ult freezer could be divided into 3 kinds according to the temperature range.

The ultra freezer is one of the main tools used in research laboratories. Unpacking 2 installation and operation manual thermo scientific ultra low temperature freezers the following symbols are used in caution warning and informational labels attached to the freezer.

Increasing freezer temperatures from 80oc to 70oc will decrease the run time of the compressor and the frequency of the start stop cycle and extend the life span of the freezer. Additionally the client s samples were mainly archival meaning employees wouldn t be frequently moving material in and out of the freezer. However such applications usually start at about 300of and go downward. 2 unpacking at delivery examine the exterior for physical damage while the carrier s representative is present.

1 60 degree freezer is fit for tuna preservation electronic devices special materials at low temperature and stored plasma biological materials vaccines reagents. In addition to the risk of losing samples the impact of ultra low temperature freezer reliability issues is important in terms of resources consumed including freezer downtime lost productivity for laboratory staff and direct expenses to the facility. An ultra low temperature walk in freezer would be more flexible upgradable energy efficient and cost effective than the current system.
