Vostok Freezers

Portable Ultra-Low Temperature Freezer


Minus80 Series

ATS’ VOSTOK, PortM80 portable ultra-low temperature freezer, is designed and manufactured specifically for the storage of medical and laboratory products. All ATS’ VOSTOK freezers are ideal for biological storage, including vaccines, viruses, germs, blood plasma, skin, bone marrow, sperm, and other biological, pelagic and special test products.

The PortM80, ultra-low temperature mobile vaccine freezer comfortably cools to -86°C in minutes, with the precise temperature control of ±0.1°C accuracy. The PortM80 solves the industries pain point of vaccine transportation with its ultra-compact size and lightweight design. The PortM80 utilizes Stirling refrigeration technology, using environmentally safe helium as the refrigerant, with high life, high safety, and high-reliability performance.

Because of the unique Stirling technology, this freezer is well-equipped to master vibration and transportation bumps. Additionally, it can be equipped with multiple Stirling coolers. During pre-cooling, multiple Stirling coolers can be started at the same time to achieve shorter pre-cooling time, and during normal operation, it can be put into a multi-prepared mode.

The PortM80 also has a remote monitoring system, providing on-site testing that ensure the quality reliability of remote monitoring
