Pipetting
Pipetting is a fundamental laboratory skill where special tools called pipettes are used to accurately measure and transfer small amounts of liquids. Think of it like using a very precise eye dropper, but for scientific work. This skill is essential in many types of labs, from medical testing to research facilities. Being good at pipetting means someone can handle samples carefully and get accurate results. It's similar to cooking where precise measurements are crucial, but on a much smaller scale. When you see this on a resume, it indicates the person has hands-on lab experience and attention to detail.
