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.
