What is a Volumetric Pipette

A volumetric pipette is a laboratory instrument used to measure and transfer a specific volume of liquid with a high level of accuracy and precision. It is designed to deliver a single, fixed volume of liquid, often to the nearest hundredth or thousandth of a milliliter.

Volumetric pipettes typically consist of a long, narrow glass tube with a bulbous portion near the top and a tapered tip at the bottom. The bulbous portion is used to draw in and dispense the liquid, while the tapered tip ensures controlled and accurate delivery.

To use a volumetric pipette, the liquid is drawn into the pipette by creating a vacuum through the use of a pipette filler or by using a mechanical device like a pipetting aid. The liquid is drawn past a calibration mark on the pipette, which indicates the precise volume to be delivered. Once the liquid reaches the desired volume, the pipette is carefully emptied into a receiving vessel by touching the tip of the pipette to the wall of the vessel and allowing the liquid to flow out.

Volumetric pipettes are commonly used in analytical chemistry, pharmaceutical research, and other scientific applications where precise volume measurements are essential. They are particularly useful when working with solutions that require accurate dilutions or when preparing standard solutions with precise concentrations.
