Guide and selection support
ULT -150°C freezers are used in molecular biology and life science laboratories to stably store sensitive biological and chemical samples such as DNA, RNA, proteins, or vaccines over extended periods. The ultra-low temperature ensures minimal metabolic activity and long durability.
When selecting such a freezer, besides the achieved temperature limit of about -150°C, factors like energy efficiency, volume, temperature stability, and ease of maintenance also play an important role. Compatibility with existing storage containers and access mechanisms should be considered as well.
LabFinder offers guidance in searching for suitable units of this specialized refrigeration type by transparently describing relevant features, commonly used terms, and technical requirements.
Applications and Benefits
ULT -150°C freezers are used for long-term storage of biological samples that must be kept stable at extremely low temperatures. This includes, for example, deoxyribonucleic acid (DNA), ribonucleic acid (RNA), proteins, vaccines, and cell extracts. The ultra-low temperatures of around -150°C prevent degradation of sensitive molecules due to enzymatic or chemical processes.
Selection Criteria
Key factors when choosing a ULT -150°C freezer are temperature stability and accuracy, storage volume, energy efficiency and noise level, as well as user convenience and maintenance effort. Access to samples and integration into existing laboratory structures are also important aspects. Additionally, it should be checked whether appropriate storage containers are compatible for this temperature class.
Variants and Designs
The units mainly differ in the cooling method, such as Stirling engines or traditional compressor technology, as well as in their size and power supply. While the measurement principle is not relevant here, technical variants are available depending on performance and space requirements.
Calibration and Maintenance
Regular monitoring of temperature values and maintenance of the cooling units are essential for smooth operation. Calibration is usually carried out by external temperature probes and protocols, which ensure precise monitoring of -150°C. Cleaning and technical inspections further support the lifespan of the device.
Application Limits
Not all biological samples require temperatures as low as -150°C; in many cases, -80°C is sufficient. For some applications, the increased energy demand and maintenance requirements of a ULT -150°C unit need to be considered. Storing samples at such low temperatures is technically demanding and more costly compared to moderate freezers.

Frequently asked questions
How does a ULT -150°C freezer work?
A ULT -150°C freezer uses specially developed cooling technologies such as Stirling engines or high-performance compressors to achieve and consistently maintain temperatures down to around -150 degrees Celsius, enabling long-term stable storage of biological samples.
Which samples are typically stored at -150°C?
Mainly biological samples such as DNA, RNA, proteins, vaccines, and cell fractions are stored at these ultra-low temperatures to ensure molecular integrity over extended periods.
What should I consider when selecting a ULT -150°C freezer?
Besides temperature stability and storage volume, energy consumption, user comfort, ease of maintenance, and compatibility with existing storage containers and laboratory workflows are important factors.
How is a ULT -150°C freezer serviced and calibrated?
Maintenance includes regular cleaning, inspection of the cooling technology, and temperature controls. Calibration is usually carried out with external temperature sensors to ensure reliable measurements under ultra-low conditions.
What are the limitations of storage at -150°C in the laboratory?
Extremely low temperatures require high energy usage and detailed maintenance. Not all samples require -150°C—often, -80°C is sufficient. Moreover, freezers of this class are technically complex and expensive to operate.
