Application and configuration
Designed for biological-sample storage in liquid nitrogen. Monitoring supports routine inspections but does not replace the laboratory’s nitrogen-level checks and operating procedures.
Static evaporation and holding-time values describe rated test conditions. Frequent access and operating conditions change the practical refill interval.
Alternative vial and blood-bag capacities require their specified optional inventory systems and compatible sample containers. Wi-Fi/cloud, backup battery and roller base are optional.
Does it refill nitrogen automatically?
CryoEssence monitors temperature and level but is filled manually. Automatic filling is not part of the standard configuration.
Is static holding time the refill interval?
No. It is a rated value under static conditions. Actual refill intervals depend on access frequency, load and operating conditions.
