The Ultra Freezer is one of the main tools used in research laboratories. The ULT freezer safeguards biological samples by keeping them at very low temperatures.The operating temperature can range from -45°C to -86°C. Several features make an ultra low freezer an extremely reliable solution for laboratory research.

Ultra Low Temperature freezers are designed for storage of biological materials such virus, bacteria, eukaryotic cells, blood and semen. These freezers are used in blood banks, hospitals, epidemic prevention services, research institutes, and biomedical engineering facilities. Bench top and under counter models can accommodate lab space limitations. Look for low-noise technology, superior energy efficiency, LED display of temperature and alarm codes; customizable extended warranties and preventive maintenance plans.
