The Vacc-Safe VAC-86L108 is an ultra-low temperature freezer designed for the safe storage of vaccines, medicines, laboratory products and samples between -40°C and -86°C. VIP Plus insulation delivers up to 30% more usable storage capacity than a conventionally insulated freezer of the same footprint, while improved heat dissipation extends the lifespan of core components. A multi-layer silicone sealing structure provides a tight seal between the inner and outer doors for better insulation, and a heated pressure equalization port allows the main door to be reopened quickly after closing. A built-in backup battery, providing up to 52 hours of protection, keeps the unit running and monitored during power interruptions. -40°C to -86°C temperature range
