Liquid Nitrogen Tank Calibration｜Liquid Level & Temperature Verification｜READY Biotech

Liquid nitrogen tanks (Dewar flasks) are essential for long-term storage of biological samples such as cell lines, embryos, gametes, and reagents.
Since liquid nitrogen gradually evaporates and must be replenished, maintaining sufficient liquid levels and stable low temperatures (typically below -150°C) is critical to prevent sample loss.

Regular calibration of liquid nitrogen tanks ensures compliance with safety standards and provides traceable documentation for GMP/GLP audits. READY Biotech offers on-site calibration and comprehensive reports to help safeguard your valuable samples.

☛ Calibration Scope:
▪︎ Liquid level measurement – using calibrated liquid level meters to verify LN₂ refill cycle and safety margin.

▪︎ Temperature verification – placing multiple temperature probes inside the storage area to confirm stable low-temperature conditions.

▪︎ Long-term data recording – e.g., recording one data point every 5 minutes for at least 1 hour.

▪︎ Liquid level trend analysis – assisting customers to estimate LN₂ refill intervals.

▪︎ Calibration report – including liquid level records, temperature profiles, data statistics, and compliance statement.

☛ Applicable Tank Types:
▪︎ Open-top liquid nitrogen tanks
▪︎ Automatic refill liquid nitrogen tanks
▪︎ All brands and models (domestic and imported)

✅ Sample Report Contents:
▪︎ Calibration environment record (ambient temperature / humidity)
▪︎ Equipment information (brand, model, serial number)
▪︎ Liquid level and temperature raw data with deviation analysis
▪︎ Traceability certificates of test instruments
▪︎ Authorized signatures and compliance statement (ISO/IEC 17025 format)
