Laboratory Freezer Calibration Services (-20 to -80 °C)

OSI provides professional laboratory freezer calibration services to ensure accurate temperature control, sample integrity, and regulatory compliance. Freezers operating in the -20 °C to -80 °C range are essential for preserving biological samples, pharmaceuticals, and research materials, where temperature excursions can result in irreversible degradation.

Our experienced technicians perform precise calibrations on a wide range of laboratory and ultra-low temperature (ULT) freezers to verify performance under normal operating conditions.

Scope of Services

Calibration of setpoint versus actual temperature
Evaluation of alarm setpoints (high/low temperature alarms)
Review of monitoring systems and data loggers (if applicable)

Methodology

OSI utilizes NIST-traceable, calibrated instrumentation designed for low and ultra-low temperature environments. Measurements are collected within the usable storage space under typical operating conditions. Services are single-point verification expectations.
