DESCRIPTION

A mechanical cryogenic freezer is used for the long-term cryopreservation of samples such as cell cultures, tissue samples, bacteria, viruses and non-biological products such as electronics. Applications include cord blood preservation, biobanks, reproductive procedures, blood banks, life science research, biomedical engineering and fisheries. Mechanical cryopreservation is a safe alternative to LN₂ and can reduce or eliminate the reliance on LN₂, reducing safety concerns.

Features

Energy Efficient Hydrocarbon Refrigeration

• Includes specialist industrial compressor, hydrocarbon refrigerant, dual-compressors 4-stage cascade refrigeration system, which delivers excellent energy-efficiencies
• Energy-efficient fan design with intelligent start/stop
Environmentally Friendly

• 100% HC refrigerant truly environmentally-friendly refrigeration system with zero global warming potential (GWP)
• LBA polyurethane foam has low GWP and is significantly lower than most HFCs commonly used, offering better environmental protection
Superior Uniformity

The temperature uniformity is ±5°C with the setting temperature of -150°C
Low Noise

Noise-reduction features and noise reduction design lowers to noise to 55 dB (A)
Safe, Secure and Reliable

Multiple alarms, including high and low temperature, power failure, door ajar, hot condenser, low battery, sensor error, and high ambient temperature. The standard ambient temperature ranges from 10°C to 32°C. The pressure state of the system can be automatically adjusted by the pressure controller to prevent the pressure from being too high to effect the freezer operation.
