Ultra-low temperature freezers are essential for storing sensitive biological samples, vaccines, and other materials requiring extreme cold conditions. Their storage capacity typically ranges from 200 to 800 litres, designed with internal shelves and doors to ensure temperature uniformity. These freezers maintain temperatures as low as -86°C (-186.5°F) and include advanced features like cascade refrigeration, alarms, and ergonomic designs for optimal performance and user convenience.
Key Points Explained:
-
Storage Capacity Range
- The standard storage volume for ultra low temperature freezers spans 200 to 800 litres, accommodating diverse research and medical storage needs.
- Smaller units (~200L) suit labs with limited space or lower sample volumes, while larger models (~800L) are ideal for high-throughput facilities.
-
Internal Design for Efficiency
- Shelves with individual doors minimize temperature fluctuations when accessing samples.
- Uniform cooling is critical for preserving sample integrity, especially for vaccines or cell cultures.
-
Temperature Performance
- Capable of maintaining -86°C (-186.5°F), these freezers use cascade refrigeration systems for reliability.
- Features like rapid temperature recovery and homogeneity ensure stability during frequent door openings.
-
User-Centric Features
- Safety: Visual/audible alarms alert users to temperature deviations.
- Ergonomics: Smart handles and frost-reduction designs improve usability.
- Compliance: F-gas conformity meets environmental regulations.
-
Selection Considerations
- Assess sample volume and access frequency to choose between compact or large-capacity models.
- Prioritize units with robust construction and energy-efficient designs for long-term cost savings.
For specialized applications, such as biobanking, verify that the freezer’s recovery time and alarm systems align with regulatory standards.
