Large-capacity liquid nitrogen (LN2) storage systems are essential for the long-term preservation of cell lines, tissue samples, embryos, vaccines, and biologics. Since these systems operate at an extreme cryogenic temperature of -196℃, any deviation in temperature or insufficient liquid levels could lead to irreversible sample loss. Therefore, regular validation is critical for laboratories and pharmaceutical facilities.

Validation items:

▣ Temperature Verification (-196℃)
Multiple LN2 probes are placed inside the storage tank to record actual temperatures, ensuring stable operation at -196℃ within acceptable tolerance.
This confirms uniformity and reliability of cryogenic conditions.

▣ Liquid Level Measurement
Verification of liquid nitrogen level sensors or manual measurement devices, comparing displayed values with actual measurements.
Ensures alarms and refill mechanisms function properly to protect samples.

▣ Validation Report
READY provides comprehensive reports including temperature curves, liquid level monitoring records, reference standard traceability, and compliance analysis, suitable for GMP/GLP audits.

With our rigorous validation process, clients can ensure their liquid nitrogen storage system operates reliably and securely, safeguarding valuable biological samples.
