How to Get 15-50% More ULT Sample Storage from Your Limited Floor Space

At Stirling Ultracold, we recognize that laboratories and biorepositories have a limited amount of floor space. That’s why our unique ULT freezer design delivers more storage capacity per square foot than other comparable models, giving you the most use of your floor space. With our compact Stirling engine cooling technology, less than 11% of our SU780XLE’s outer cabinet volume is needed to house its mechanical cooling system. That’s remarkably smaller than compressor deck space required in other ULT freezers, which is why you get so much more storage capacity in a smaller footprint with a Stirling freezer.

How Much More Sample Storage Do You Get Per Square Foot?
Our unique freezer design allows you to store 15-50% more 2ml vials per square foot of floor space (per freezer) when compared to other upright models of similar size.

Here’s another way to look at this . . . With the smaller footprint of our 600-box-capacity SU780XLE, you can place two additional ULT freezer units in a 50-foot row (side-by-side arrangement with recommended clearance), versus competitive models. This equates to a difference in storage capacity of 1,200-2,200 additional 2” sample boxes, or 120,000-220,000 additional sample vials within the same floor space!

Also, the Stirling Ultracold SU780XLE can be placed directly against the walls in your space, whereas competitive models require an additional 6-8 inches behind the freezer for ventilation clearance. This increases our footprint advantage even further. 

Our Stirling engine cooling technology is located at the top of our freezers, inside the green top. This places more racks within easier reach, while significantly improving system access and serviceability. In other ULT freezers, compressor-based cooling systems are located at the bottom of the freezer where service access is more limited.

With our innovative cooling system and unique design, we provide the most ULT storage capacity for your limited floor space, in addition to keeping your samples safer than they’ve ever been.

Stirling Ultracold’s Facility Earns Zero Waste Certification

I am very pleased to announce that Stirling Ultracold has received Zero Waste Certification from Green Business Certification, Inc. (GBCI), an independent certifying body that recognizes excellence in green business industry performance and practice globally. GBCI conducted an on-site assessment of our facility, reviewed our policies and practices, as well as our diversion data for the past year.  By adhering to the US Zero Waste Business Council’s and Zero Waste International Alliance’s rigorous standards for diverting waste from both incineration and landfill, this certification confirms our commitment to fulfilling the shared environmental sustainability goals and initiatives of our customers.

For us, becoming a certified Zero Waste facility is not a mere symbol or marketing pitch. Our success in reducing, reusing, and recycling waste is an extension of our core values, which have driven Stirling Ultracold’s products and approach to the research community since our beginnings. We have always believed that it is possible to align finding cures for diseases with sustainability. That is why every ultra-low freezer we manufacture supports sustainability and climate action goals with 100% natural refrigerants, industry-leading energy efficiency and the smallest possible carbon footprint. As we shared last year in our post, Why We’re Becoming a ‘Zero-Waste’ Manufacturer… Not Just ‘Zero Landfill, our Zero Waste program is part of our larger commitment to help research organizations achieve their corporate sustainability initiatives.

Having recently announced our new ENERGY STAR® partnership and certification of the most energy-efficient ULT freezer in the industry, earning Zero Waste certification is another important sustainability milestone for Stirling Ultracold because it validates our authenticity in supporting the values of our customers.
