The Stirling Ultracold SU780XLE is the most reliable and energy-efficient upright ultra-low temperature (ULT) freezer available. Compared to other compressor-based ULTs, the SU780XLE:

✔ Costs less to operate
✔ Saves valuable laboratory space
✔ Reduces your energy use
Compressor technology is expected to fail — putting your valuable samples at risk. But because the SU780XLE uses Stirling engine technology, which outlasts compressors, it keeps your samples safer.
You depend on valuable — often irreplaceable — biological materials to further your laboratory’s research. Don’t compromise the integrity of your specimens with less reliable, compressor-based ULTs that are prone to failure.
• KEEP YOUR BIOLOGICAL MATERIALS SAFER : Maintains consistent temperatures (within +/-1°C at steady state) and quickly returns to s etpoint when its doors are opened, keeping your samples safe.
• REDUCE YOUR LABORATORY POWER USE AND COSTS : Uses 70–75% less energy compared to stan dard compressor-based ULTs. In addition to reducing your ULT energy costs — because it generates 70–75% less heat than other units — you’ll reduce your HVAC costs.
• MINIMIZE MAINTENANCE: With only a few moving parts and no oil anywhere in the system, there is virtually no maintenance required to keep it running at peak perfo mance. Fewer components mean less risk of failure — and less risk to samples.
• IMPROVE YOUR LABORATORY SUSTAINABILITY: With the industry’s top ENERGY STAR® rating, you’ll use less e nergy and reduce your operating carbon footprint. The SU780XLE contains 100% natural refrigerants and is manufactured in a zero-waste facility, making it the most environmentally sustainable ULT available.
• SAVE VALUABLE LAB SPACE: The SU780XLE has the largest storage capacity per square foot/meter of floor space, so you can store more samples in less space. With high-density sample storage, you may be able to purchase fewer freezers while also saving valuable lab real estate.
• LOWER YOUR TOTAL COST OF OWNERSHIP: With its low energy use and associated infrastructure, minimal maintenance requirements, reduced floor space and longer operati ng life, the SU780XLE has the lowest total cost of ownership for any ULT.
