Choosing a reliable ULT freezer: What you need to know
Ultra-low temperature (ULT) freezers are all too often unsung heroes in laboratories, playing a crucial role in preserving precious samples and valuable products. Reliability in ULT freezers is therefore critical for uninterrupted lab operations. But how can you accurately assess reliability when selecting your next ULT freezer? In this blog, we discuss the importance of ULT freezer reliability and highlight some key performance metrics to consider in your decision-making process.

Defining reliability in ULT freezers
Reliability in ULT freezers refers to the predicted amount of time a freezer will perform its expected function under stated conditions without failure. For lab scientists, this means ensuring that your ULT freezer consistently protects your valuable samples over the long term, maintaining ultra-low temperatures with minimal fluctuations.
Why is ULT freezer reliability crucial for labs?
Investing in a ULT freezer that reliably safeguards your critical samples is of the utmost importance. A reliable freezer helps minimize the risks of:
- Operational disruption: Avoid the costly delays and setbacks that can be caused by unexpected breakdowns.
- Sample or product loss: Protect against the loss or compromise of valuable biological materials — temperature fluctuations or complete failure in unreliable freezers could lead to sample degradation or loss.
- Cost-effectiveness: Reliable freezers typically require less maintenance and can have a longer operational life, helping to reduce total ownership costs.
Key performance metrics that indicate ULT freezer reliability
When evaluating ULT freezer reliability, several performance metrics can provide valuable insights:
- Temperature stability: Measures how consistently the freezer maintains its set temperature. Look for freezers with minimal temperature fluctuations over time.
- Temperature uniformity: Indicates how evenly the temperature is distributed throughout the freezer. A reliable ULT freezer should maintain consistent temperatures across all storage areas.
- Recovery time after door opening: Measures how quickly the freezer returns to its set temperature after the door has been opened. Faster recovery times generally indicate better reliability.
By focusing on these metrics, you can select a ULT freezer that is likely to perform reliably and efficiently in the long term.
When interpreting these metrics, it's important to consider the testing conditions used. Factors such as ambient temperature, frequency of door openings, and load capacity can all affect performance results.

Making a reliable choice
Choosing a reliable ULT freezer is crucial for the efficiency of your lab operations and the integrity of your research. When selecting a ULT freezer, in addition to reviewing key performance metrics, consider gathering real-world insights from colleagues and repair technicians, and don't hesitate to ask for custom testing for your specific application. Afterall, a dependable ULT freezer does more than preserve samples; it helps ensure reproducible results and provides peace of mind that your valuable work is protected.
