Pipettes are the primary tools that laboratory scientists use each day, perhaps as a hammer is to a roofer. They provide accurate measurements of very small volumes of liquids in the user’s quest to obtain correct test results. But pipettes are mechanical devices that require regular calibration service to maintain their accuracy and precision. The similarities are not unlike the maintenance of your car. Without regular service and repair, your car can break down, leave you stranded and result in high repair costs. Pipettes are no different. Let’s explore this further, directing our focus to the measurement science and relevant standards.
