Description
The Stirling VAULT100 freezer features a more robust engine, unprecedented temperature uniformity and range, and an updated interface that shares freezer health analytics.
The new thermodynamically engineered cabinet design, three sealed inner doors with high-strength magnetic latch, and ambient air-repelling door gaskets maintain temperature uniformity at ±3 °C at -80 °C. The VAULT100 can operate down to -100 °C and delivers fast recovery after door openings to protect the integrity of your samples.
Designed to deliver lower lifetime cost of ownership through energy efficiency, large storage capacity, and lower maintenance and HVAC costs.
