What is volumetric pipette?

A volumetric pipette is a type of laboratory glassware used to measure and transfer a specific volume of liquid with high precision. It is designed to deliver a single, accurate volume of liquid, typically to the nearest hundredth of a milliliter.

Volumetric pipettes have a tapered tip and a single graduation mark on the pipette body, indicating the calibrated volume. They are calibrated to deliver or contain a specific volume of liquid at a specific temperature, usually 20 degrees Celsius. Volumetric pipettes are commonly available in sizes ranging from 1 mL to 100 mL.

To use a volumetric pipette, the liquid is drawn into the pipette by creating a vacuum with a pipette filler or bulb. The liquid is then dispensed by allowing it to flow out of the pipette tip through controlled pressure. It is important to ensure that the liquid does not cling to the walls of the pipette, as this can lead to inaccuracies in volume measurement.

Volumetric pipettes are commonly used in analytical chemistry, pharmaceutical laboratories, and other scientific applications where precise volume measurements are required. They are calibrated and inspected regularly to ensure accuracy and reliability in laboratory experiments and procedures.
