User-induced pipette

A user-induced pipette is a manual device used to draw, transfer, and dispense small volumes of liquids in laboratory or clinical settings. It consists of a slender glass or plastic tube with volume markings and relies on the user creating suction—either by mouth or via a squeezable bulb—to aspirate and hold fluid, then releasing it through controlled venting or bulb compression.

These devices are typically supplied as non-sterile, reusable tools intended for general laboratory use and are not classified as medical devices when used for non-clinical purposes. When employed in clinical contexts for handling patient specimens or reagents, they may fall under general laboratory equipment regulations and are subject to local requirements for calibration, cleaning, and maintenance, but are not inherently regulated as medical devices unless specifically intended for a medical purpose.
