pipetted

Pipetted refers to the action of transferring a liquid using a pipette. A pipette is a laboratory tool commonly used in quantitative research to measure and transfer small amounts of liquid precisely. There are various types of pipettes, including volumetric pipettes, graduated pipettes, and micropipettes, each designed for different purposes and volumes.

The process of pipetting involves several steps. First, the desired volume of liquid is set on the pipette, either by adjusting a plunger or selecting a pre-set volume on a digital device. Next, the tip of the pipette is immersed into the liquid to be transferred. A controlled upward movement of the plunger or activation of a button draws the liquid into the pipette's tip. The pipette is then moved to the receiving vessel, and the liquid is dispensed by pressing the plunger or activating the dispensing mechanism. Proper technique is crucial to ensure accuracy and avoid contamination. This includes using the correct pipette for the volume, ensuring a good seal on the tip, and performing aspiration and dispensing at consistent speeds. In scientific experiments and chemical analyses, accurate pipetting is fundamental for obtaining reliable results.
