Laboratory low temperature freezer

Laboratory low-temperature freezers use a compressor-based refrigeration system to lower the internal temperature, typically reaching -20℃ to -86℃. They are used to store temperature-sensitive materials such as biological samples and reagents to prevent degradation and spoilage. These freezers are commonly found in sample repositories and laboratories of medical and research institutions.
Selection
When selecting, consider the temperature range to match storage needs, check whether the effective volume and shelf configuration are suitable. Pay attention to the type of compressor as it affects noise and energy consumption, and inspect the thickness and sealing of the insulation layer. Confirm the alarm system and temperature recording functions, and evaluate whether the equipment dimensions fit the laboratory space.
