An ultra-low-temperature deep freezer is a must-have in any research laboratory, as it is essential to extend the life cycle of various materials, thus reducing the waste of expensive resources.

The operating temperature ranges from -45 to -89 degrees, in fact we refer to this instrument in most cases with the name -80 ultra-low freezer.

Ultra Low Laboratory Freezers

The low temperatures that an ultra low laboratory freezer can reach are suitable for scientific, in particular medical, but also industrial applications. 

There are two types of ultra-low freezers available on the market: vertical (upright) and horizontal (chest) ultra freezer.

Those of the first type are the most common, because of space and mobility issues.

However, as far as technical and operating specifications are concerned, there are no substantial differences, apart from the portability inside the laboratory.

Therefore it is possible to configure the ideal ultra low lab freezer for your logistic requirements, without affecting its performances.

The FDM Ultra-low freezers

FDM manufactures ultra-freezers with a cascade compression unit, fast, efficient and well-built. Below the main features:

  • The internal coating of these devices, insulated from the outside by polyurethane, is in stainless steel. The FDM ultra-low-temperature freezer is divided in internal compartments, so to better organize the different samples.
  • The shelves are easily adjustable, so to meet the requirement for different heights.
  • The solidity and insulation capacity ensure that the internal temperature is always maintained, even in the event of a power failure
  • The LCD display is extremely intuitive and provides the possibility, in addition to monitoring all parameters and alarms, to be able to record the temperature trend through a graph.

Optionally, the ultra-low freezer can be equipped with an emergency temperature backup system, that is activated in the event of a failure in the main power supply.

There are several volumes available, starting with a benchtop ultra low freezer of 100 liters capacity (small ultra low temperature freezer), to a 650 liters version.

Maintenance is simple and fast and costs are among the most competitive on the market. 

FDM is among the best ultra low temperature freezer manufacturers. Our products are 100% hand made in Italy, built with the best components available, and synonyms with efficiency and reliability since 1949.

All the above is still not matching with your requirements?
