  1. Why Calibrate Gravimetric Pipettes?

    Why Calibrate Gravimetric Pipettes?

    Right on the heels of a blog published on Laboratory-Equipment.com called “How to Improve Pipetting Techniques,” we present this discussion about calibration of gravimetric pipettes. Most labs are required to complete periodic calibration of instruments, as per documented protocols. Whether the tasks are performed by lab staff or a vendor, it’s a time-consuming and exacting process. The alternative? Data and test results that may be questioned or challenged.

    Considerations for Calibration

    Pipette calibration is performed by laboratories to ensure that their pipettes are functioning within given (documented or established) parameters. In fact, pipettes that are not routinely calibrated can produce vastly different dispensing volumes than expected, which results in ambiguous or even erroneous data sets.

    Controlling microbial contamination is one of the leading concerns in research, clinical, and medical facilities. Microorganisms (hazardous or not) can put personnel, patients and caregivers at risk. In hospital and medical facilities, patients are often immuno-compromised or have serious conditions that make them particularly susceptible to opportunistic microbes or secondary infections.

    For these reasons, many products are available for decontamination of these critical spaces. There are differences in product effectiveness, cost, potential residual damage and operat
