Vacc-Safe DualGuard ULT Medical Freezer -86°C
Protect Large Sample Collections at -86°C with the Vacc-Safe DualGuard ULT Freezer
Large sample collections are costly to replace. A freezer fault can put the whole collection at risk.
The Vacc-Safe DualGuard ULT freezer range holds -86°C to -40°C in sizes from 458L to 860L. Racks are not included.
Back Up Your Cooling with the Vacc-Safe DualGuard ULT Freezer's Twin Systems
A single cooling system is a single point of failure.
The VS-86L568S, VS-86L580BS, VS-86L708S, VS-86L720BS and VS-86L818S have twin refrigeration systems. Vacc-Safe states that if one system fails, the other can maintain the freezer's temperature uniformly.
Cut Energy and Noise with the Vacc-Safe DualGuard Inverter ULT Freezer
Fixed-speed compressors run loudly and use more energy.
The same five models have an inverter compressor. Vacc-Safe states inverter compressors offer better energy efficiency, lower noise and greater durability than fixed-speed motors. A patented D-shape evaporating tube increases heat exchange for faster pull-down and recovery.
Manage Samples Door by Door with the Vacc-Safe DualGuard ULT Freezer
Opening one big door exposes the whole freezer to warm air.
The VS-86L458S, 568S, 580BS, 708S, 720BS and 818S have four independent, detachable inner doors, each with its own gasket. Multi-layer gaskets also seal the inner doors against the outer door. A heated pressure equalization port on the same models lets the door open faster after it has been closed.
Control Your Vacc-Safe DualGuard ULT Freezer from a 10-Inch Touch Screen
Small displays make settings hard to read and change.
The seven L models have a 10-inch touch screen. The door locks, a safety lock adds protection, and audible and visual alarms warn your team. A built-in battery keeps the display on when power is off, and a porthole gives cable access.
