Freezers are refrigeration equipment that is composed of a thermally insulated compartment, which allows it to keep cold and thus avoid damage or degradation of substances. These equipments maintain the cold by compression or by absorption, being able to maintain temperatures below 0 ° C, usually between -30 ° C and -4 ° C, although more modern frerzers can reach temperatures of -80 ° C .
These machines are generally made of robust and durable materials, such as stainless steel, aluminum or powder-coated sheet steel. The laboratory freezers have a selection of distributors or internal storage compartments, some of which can be configured by the user. They can also have combinations of doors, baskets, shelves, adjustable and interchangeable trays that have been designed for use in the freezing process.
They are teams that are generally not very demanding from the point of view of maintenance, but they are with regard to the electrical power system. However, if they are connected to good quality electrical systems and have adequate ventilation around them, they can work for years without requiring specialized technical service.
What is the function of a laboratory freezer?

What characteristics to consider when choosing a laboratory freezer?
The choice of a laboratory freezer should be made taking into account, in addition to the intended use, the capacity, the temperature range it offers, the configuration, and the number and type of doors.
- Capacity: the storage volume is decisive and your choice will depend on the type of service for which the refrigerator will be used.
- Temperature range: it is a very important criterion. Most refrigerators have a temperature range between -80 ° C and -4 ° C, according to quality standards.
- Configuration – to be chosen based on available space in the lab or pharmacy. Vertical freezers are the most common, but there are also horizontal refrigerators.
- Number and types of doors: Refrigerators can have between one and four doors.
