These products have the performance, reliability, and efficiency required by your lab with the emphasis on environmental sustainability that matters most in science and life.

What Makes Stirling Ultracold Freezers Different? (Brand Overview)

Unlike most other traditional ULFs that make use of compressors in their cooling mechanism, Stirling Ultracold freezers make use of their patented free piston Stirling engine technology in order to attain ULT temperatures. Such technology is very advanced and is mainly previously used in aerospace and industrial sectors, where temperature control is of great importance. Even though it was exclusively used in those fields, it is of great advantage as it helps in solving problems associated with ULT and energy consumption.

Key benefits of this technology include:

• Lower energy consumption compared to traditional compressors helps laboratories cut operating costs and HVAC load.

• Reduced maintenance, since there's no compressor oil, and fewer parts are involved that need regular servicing.

• Temperature stability-a must for maintaining sample integrity over an extended period.

• Natural refrigerants that have a lesser impact on the environment, resulting in environmental sustainability.

Stirling Ultracold's commitment to sustainability has received industry recognition through ENERGY STAR certification and ensures energy-saving performance with a lower environmental footprint compared to traditional ULT freezers.

Stirling Ultracold Product Range

The range of equipment by Stirling Ultracold includes several ultra-low temperature freezers designed for various storage needs, ranging from benchtop suitability to larger equipment such as biobanks. Here’s a closer look at major product types and what they offer:

Stirling Ultracold ULT25NEU Portable Freezer , Portable Ultra-Low Temperature Storage

This ULT25NEU product represents a major breakthrough for laboratory and clinical teams that need ultra-low temperature storage and ultra-cold temperature control anywhere needed. For instance, this ultra-cold storage unit weighs around 46 pounds; therefore, it is uniquely designed to be:

• Portable and lightweight, Suitable for Point Of Care, Remote Site, Field Research, and Field Clinic use.
  

• It is also flexible in its power options; it may run on either AC mains, 12V DC from automotive sources, or batteries taken from external sources. This helps extend its uses beyond the lab.

• Wide-range temperature control, adjustable from -20°C to -86°C, for infectious materials, biologics, and vaccines, and more.

• Robust and energy efficient, design requires considerably less energy than conventional compressor freezers and uses 100% natural refrigerants.

With a compact storage volume of around 25 liters and storage capacity for up to 18 standard 2″ boxes, the ULT25NEU now allows for the safe storage of thousands of vials or doses without the need for dry ice, which can be advantageous for teams or organizations outside conventional laboratory settings.

This portable version also has optional remote monitoring systems that allow users to monitor the temperature or system status through cloud-based software for compliance purposes.

Stirling Ultracold SU105UE -86C Undercounter Freezer, Compact Undercounter Ultra-Low Freezer

For those with limited space or seeking a "personal or dedicated UCT storage solution," the SU105UE is an impressive piece of equipment. It harnesses the trusted power of Stirling Engine technology in a compact package that can fit under benches, counters, and stacked spaces.

Key features include:

• Robust temperature range from -20°C to -86°C with 1°C increment control, making it serviceable in various biological storage requirements.

• 105-liter storage capacity, users can store approximately 72 standard 2″ sample boxes with optional racks for efficient usage of space within the storage device.

• Fast, uniform temperature pull-down and stable operation with reduced temperature fluctuations to ensure sample quality.

• Low maintenance design, due to the use of Stirling technology eliminating the need for typical service associated with a compressor system.

Due to its size and flexibility, the SU 105UE is particularly popular in clinical research labs, small-scale bio-banks, and other areas wherein a secure accommodation of ultra-cold storage at each station is a prime concern.

High-Capacity Upright Freezers 

For laboratories and bio banks that demand maximum storage density, Stirling Ultracold's upright ultra-low-temperature freezers offer superior capacity with minimal footprint. Although specific product model numbers within this particular vendor segment may vary, the VAULT100, which may be obtainable through distributors, is characteristic of this particular vendor segment.

These upright freezers provide:

• Large storage volumes, that have sufficient space for hundreds of standard sample boxes – making it suitable for biobanks, large-scale research facilities, and clinical sample repositories.

• Advanced temperature control down to -100°C on certain models, referred to as the VAULT100, offering deeper refrigerated storage options for certain biological materials.

• Predictive analytics and intuitive controls, providing labs with enhanced insight into freezer performance and diagnostics (where advanced interface systems are available).

• Energy-efficient operation,  which besides lowering the running cost of the freezers can also contribute to the reduction of the laboratory's overall energy consumption and HVAC requirements.

Such systems are designed to accommodate high-density biobanking and preservation of valuable research materials.

Real-World Applications of Stirling Ultracold Freezers

Stirling Ultracold freezers have won widespread trust in many fields, such as science, medicine, and biotechnology:
