Accuracy
The temperature can be precisely specified and accurately maintained at all times. The uniformity of temperature along and between straws or cryovials also ensures greater consistency and greater success.

Precision Temperature Control
The rate of cooling and thawing is variable, according to user requirements. Temperatures can be held constant at any point within the control range. Controllers can also be used to provide controlled-rate specimen thawing. Thermometry and temperature control circuits are calibrated to accuracies of better than ±0.1°C.

Safety
Only small amounts of liquid nitrogen are required. There are no pressurized LN2 vessels, and no alcohol or other volatile, toxic or flammable liquids are used.

Efficiency and economy
Consumption of LN2 is less than 1 liter per hour. The low power consumption, typically less than 60 watts, makes battery power practical. There are no other consumables.

Proprietary circuit design and component selection ensure that calibrations have long term stability, contributing to low maintenance and reduced service costs.

Reliability
The freezers use only solid state integrated circuitry. There are no compressors, solenoids, fans or valves with moving parts to inevitably wear out. The freezers are vibration free and noiseless.

Versatility
With models using CryoGenesis™, practitioners can design and use an unlimited number of temperature programs of varying complexity, with up to 50 ramps and unlimited duration. A signal tone-from the controller, computer, or both can be included in the program to alert the operator when intervention is required, for example, at "seeding" temperature and/or at program finish. In the CL8800 model, up to 16 programs can be preinstalled to allow the unit to operate without a computer; yet temperature datalogging facility in CryoGenesis is still active, so temperature cycles can be validated even in preprogrammed mode of operation.
