Why 4°C Refrigerator Validation Is Essential

In biotechnology labs, QC units, pharmaceutical storage, and sample preservation workflows, 4°C refrigerator validation ensures temperature accuracy, sample integrity, and compliance with QA/SOP requirements.

Functional Inspection (Per Customer Requirement)

READY performs a complete functional check before temperature mapping:

• Exterior condition
• Door function check
• Gasket sealing condition
• Control panel button inspection
• Display accuracy check
• Operation & noise evaluation

This step helps identify early issues such as temperature fluctuation, air leakage, or mechanical wear.

6-Point Temperature Mapping (12 Hours)

Once the temperature stabilizes, we begin 6-point mapping:

• Continuous 12-hour temperature recording
• Raw data provided
• Temperature curve graph included
• Validation result based on customer acceptance criteria

This evaluates Uniformity and Stability of the refrigerator.

Uniformity & Stability Evaluation

We analyze maximum point-to-point variation and verify continuous temperature stability throughout the recording period.

Validation Result & Recommendations

If deviations occur, our report provides:

• Nonconformity findings
• Possible causes
• Suggested corrective actions
