Product overview

Designed for ultra-low-temperature storage of research samples and biological materials. The microprocessor controller and LED display show cabinet temperature, ambient temperature and supply voltage. Audible and visual alarms help alert users to high/low temperature, door opening, system faults and low battery. A powder-coated steel exterior, 304 stainless-steel liner, VIP insulation, cyclopentane foam and seven-layer door seals help reduce heat transfer. The cabinet has one outer door and two inner doors, with height-adjustable 304 stainless-steel shelves for organized sample storage.
