    Laboratory refrigerator/freezer/incubator calibration

    Calibrating a laboratory refrigerator, freezer or incubator is essential for several important reasons, all of which contribute to the accuracy, reliability and safety of laboratory work.

    Why do I need to calibrate my refrigerator, freezer or incubator?

    Calibrating a laboratory refrigerator, freezer, or incubator is a critical step that underpins the accuracy, reliability, and safety of laboratory activities. This process is not merely about adhering to standard protocols; it directly impacts the quality of experimental outcomes. Proper calibration ensures that these vital pieces of equipment operate within their specified temperature ranges, which is essential for the preservation of samples, chemicals, and biological specimens.

    Temperature accuracy

    Calibration ensures that the temperature inside the laboratory refrigerator, freezer or incubator is accurately set and maintained. This is crucial because many experiments, tests and the stability of various samples and reagents are highly dependent on specific and consistent temperature conditions. Inaccurate temperature control can lead to deviations that affect the quality and integrity of stored materials.

    Sample and material integrity

    In laboratory settings, the accuracy and consistency of experiments, research and tests depend on the integrity of stored samples and materials. Calibration helps prevent temperature fluctuations that can compromise the stability and reliability of these items over time.

    Regulatory compliance

    Many laboratories, especially those in highly regulated industries like healthcare, pharmaceutical and food testing, are required to comply with specific quality standards and regulations. Regular calibration of laboratory equipment, including refrigerators, freezers and incubators is often mandated to ensure compliance with these standards.

    Data quality

    Accurate and consistent temperature control is essential for reliable data collection, experiments and the reproducibility of results. A well-calibrated refrigerator, freezer or incubator helps ensure that the data generated in the laboratory is of the highest quality and can be trusted for decision-making.


    Proper calibration of the laboratory refrigerator, freezer or incubator reduces the risk of temperature fluctuations that could lead to sample degradation, contamination, or the creation of safety hazards. It helps safeguard both materials and personnel.

    Sample longevity

    Materials stored in laboratory refrigerators freezers or incubators, such as biological samples, chemicals, reagents, and enzymes are often expensive, sensitive, and sometimes irreplaceable. Accurate temperature control through calibration helps extend the longevity of these materials, reducing costs associated with their replacement.

    Good laboratory practice

    Calibrating your laboratory refrigerator, freezer or incubator is considered a best practice. It demonstrates your commitment to maintaining high-quality standards in your research or testing, which enhances the credibility of your work and can be important for quality assurance programs.

    Energy efficiency

    Regular calibration ensures that the laboratory refrigerator, freezer or incubator operates at its optimal performance, which can result in energy savings. This helps reduce operating costs and may also extend the lifespan of the refrigerator, incubator or freezer.

    Calibrating a laboratory refrigerator, freezer or incubator typically involves checking and adjusting the temperature control settings to ensure they match the displayed temperature and verifying that the temperature remains stable within the required range. The specific calibration procedure may vary depending on the refrigerator, freezer or incubator model and the manufacturer's recommendations.

    To ensure the accuracy of calibration, it's advisable to enlist the services of trained technicians or calibration experts who have the necessary equipment and expertise to perform the task. Calibration intervals may be specified by the manufacturer or relevant regulatory authorities and it's important to adhere to these recommended schedules.
