UMD: Laboratory devices designed to transfer programmed volumes of solution from one container to another container (e.g., microtiter plates). These pipetters typically consist of automated (e.g., electronic) or semi-automated devices that can dispense very low, predetermined volumes (typically from 0.1 microliter to several milliliters); some include disposable tips. Pipetters are used in clinical laboratories to improve the precision of measurements and lessen the possibility of cross-contamination among samples.
