Ultra-Low Temperature Freezers: A Practical Guide for Reliable Laboratory Cold Storage
What is a ultra-low temperature storage

Ultra-low temperature (ULT) storage is critical in laboratories, healthcare facilities and research environments. From biological samples to vaccines and reagents, maintaining stable temperatures as low as -86°C is essential to preserve sample integrity and ensure reliable research outcomes.

This guide answers common questions about ULT freezers and highlights the key features to consider when selecting the right solution for your facility.

What is Ultra-Low Temperature Storage and Why Does It Matter?

Ultra-low temperature storage ranges from -40°C to -86°C. At these temperatures, biological and chemical activity is significantly reduced, helping to preserve sensitive materials such as:

  • Tissue samples
  • Vaccines and pharmaceuticals
  • Plasma and blood products
  • Research reagents

Even small temperature fluctuations can compromise valuable samples and disrupt long-term studies. Reliable equipment, consistent temperature control and monitoring systems are essential for maintaining sample stability.

Frequently Asked Questions About Ultra-Low Temperature Storage:

1. What are the Main Applications of ULT Freezers?

ULT freezers are widely used across:

  • Research laboratories and biobanks
  • Hospitals and clinical settings
  • Pharmaceutical and biotechnology facilities
  • Assisted reproduction centres
  • Blood and plasma storage

Able Scientific product range covers all these applications with customised solutions.

2. What Happens if There’s a Power Outage or Equipment Failure?

Power outages or equipment failure can pose serious risks. Able Scientific addresses with:

  • Dual compressor technology to maintain temperature if one fails
  • Optional Battery backup for alarms and temperature monitoring
  • Audible and visual alarms for temperature deviation or door openings
  • Optional CO₂ backup systems for added protection


These features help safeguard samples during unexpected events.

3. How Do I Choose the Right Capacity for My Facility?

Able Scientific ULT freezers are available in a range from 110 to 800 litres to suit different facilities, from compact units for small labs to high-capacity systems for biobanks.

Key features to consider:

  • Does the unit have an adjustable shelving system?
  • What is the maximum storage capacity for cryo tubes/vials?
  • Flexible internal rack configurations to support changing needs?

Choosing the right capacity improves workflow and storage efficiency. Thanks to their modular shelving, up to 50,000 microtubes can be stored with great configuration flexibility.

4. How is the Energy Efficiency Ensured?

Energy consumption is a major consideration for ULT equipment – keeping a controlled environment at  -86 degree’s consistently is no easy task.  Our systems are designed to improve efficiency through:

  • Energy efficient dual compressor system
  • High-density insulation panels
  • Natural and eco-friendly refrigerants
  • Triple-lip gasket design (soon to be upgraded to double gaskets for better performance)
  • Inverter technology (already implemented in -40°C models, soon in -86°C models)

Efficient systems reduce operating costs while maintaining consistent performance.

5. Are ULT Freezers Easy to Maintain and Clean?

Yes, hygiene and uptime are critical in healthcare and laboratory environments. Our ULT freezers feature:

  • Accessible and washable filters
  • Durable, easy-to-clean interiors (e.g. stainless steel)
  • Removable internal components for faster cleaning

Simplified maintenance helps minimise downtime and supports compliance.

5. Can I integrate ULT Freezers with My Monitoring Systems?

Absolutely, integration with laboratory monitoring systems is important. Our freezers include:

  • Data ports (RS485) for system integration
  • USB access for data export
  • External alarm connections
  • Optional digital interfaces for real-time monitoring

These capabilities support compliance, traceability and operational control.

6. How Do You Ensure Temperature Stability and Recovery?

Frequent door openings can impact internal temperatures. Able’s High-quality ULT freezers are designed to:

  • Recover temperature quickly after door openings
  • Minimise cold air loss with internal compartment doors
  • Maintain consistent conditions across the chamber

This is particularly important in high-use environments.

Choosing the Right ULT Freezer Model for Your Facility

Your ideal solution will depend on your application:

  • Small laboratories: Compact units for limited space and lower volumes
  • Research facilities and biobanks: Large-capacity systems for bulk storage
  • Clinical environments: Mid-size units balancing access and capacity
  • Advanced facilities: Systems with full monitoring and integration capabilities

A tailored approach ensures optimal performance and long-term value.
