Our Undercounter ULT Freezer: Convenient, Compliant Personal Storage

When you don’t have enough room for a full-size ULT freezer in your lab or clinical space, Stirling Ultracold offers a smaller version of our upright freezer with the same award-winning Stirling engine technology: our SU105UE (105) undercounter ULT freezer. The 105 is a personal and lockable ULT freezer that is ideal for placing under or near your bench in the lab. This stackable model uses the revolutionary free-piston Stirling engine technology found in our SU780XLE Upright Freezer, offering a highly reliable ULT storage solution with only two moving parts, no oil and no compressors. We’ve packed convenience and reliability into one ULT freezer.

Undercounter Convenience and Space Savings- The light-weight (220 lbs./99 kg) SU105UE model is the right size for positioning under your workbench or nearby, with a surprising amount of storage space. It holds 72 two-inch boxes, making the most of its compact footprint. The quiet Stirling engine puts out much less heat than compressor-based models, providing a mixture of convenience and comfort to your work space. These benefits paired with quick and easy access allow you more time to focus on your research.

Stackable Flexibility- The SU105UE is stackable with full access to samples in an over / under configuration. This is particularly useful for placing ULT storage in labs with limited floor space, and for “staging” sample temperatures. With the widest temperature range in its class, the 105 can store biological materials from -86˚C up to -20˚C. This is ideal for clinical samples and biological drugs that must be warmed to a specific temperature in stages.

 

A “Temperature Stack” Case Study –

One example of the SU105UE’s stackable flexibility can be found at a research lab in Western Pennsylvania, where the team is taking advantage of the 105’s stackability, as well as its uniquely wide temperature range. This lab is working with a biologic drug that must be transitioned from  -80˚C to room temperature in two stages. With the range of -86˚C up to -20˚C, one of the freezers in the stack is used for the intermediate stage of the transition. Placing 105s in a stack offers a unique level of convenience and space-savings in this situation, with the flexibility to use the same freezer model at dissimilar temperatures ranges. This research team has seen improved efficiency and accuracy in the transition of these biologic materials to room temperature, while conserving precious floor space in their lab.

Secure Personalized Storage – The SU105UE model is the perfect size for personalized ULT storage. It gives you the freedom and control to organize your samples in a way that makes the most sense to you and your research. The 105 is also lockable to keep samples secure. Having a smaller lockable chamber is ideal for clinical use, where HIPAA patient privacy and access compliance standards are involved.

All the Advantages of Stirling Engine Technology – Like all of Stirling Ultracold freezers, the SU105UE can plug into any outlet worldwide, including 120V – 240V 50/60 hz. Consuming less than 4 kWh/day at -80°C, it saves energy and is environmentally friendly with 100% natural refrigerants. Because the 105’s advanced Stirling engine cooling system is inherently reliable, it comes with an industry-leading warranty that includes 7 years engine protection, with 2 years and labor cover parts coverage in the U.S. and Canada.

The SU105UE provides the perfect blend of safety, security and flexibility for your lab which will allow you to be more productive than ever.
