The word Pipette (/pɪˈpɛt/ or pi-PET) is a scientific term used to refer to a slender glass tube, used in laboratories for transferring and measuring liquids. The word derives from the Old French ‘pipette’, which means ‘to peep’ or ‘to chirp’. Interestingly, the spelling of the word "Pipette" is consistent with its pronunciation when transcribed using the International Phonetic Alphabet (IPA). This correct spelling is important in scientific communication to prevent misunderstandings or errors in experiments.
A pipette is a laboratory instrument commonly used for transferring a specific and accurate volume of liquid. It typically consists of a long and narrow cylindrical glass or plastic tube with a fine tapered tip, known as a pipette tip, at one end. Pipettes are classified into different categories based on their mode of operation and volume range.
One type of pipette is the manual pipette, which requires the user to manually introduce and release liquid by operating a plunger or button. These pipettes offer various volume options, ranging from microliters to milliliters, and are used in numerous scientific fields such as biology, chemistry, and genetics. Some manual pipettes can be adjusted to dispense volumes of different sizes.
Another category of pipettes is the electronic or motorized pipettes, which offer increased precision and ease of use compared to manual ones. These pipettes feature built-in motors for aspiration and dispensing, allowing the user to accurately control the volume with the assistance of a digital screen or controls.
Pipettes are essential tools in laboratories where accuracy and reproducibility of liquid transfers are critical. They are used for conducting experiments, preparing solutions, diluting samples, and a multitude of other tasks. Pipettes are designed to provide reliable and precise measurements, ensuring that liquids are transferred with minimal error and contamination.

The word pipette originates from the French word pipette, which means a small pipe or tube. It is derived from the Middle French word pipe, which originally referred to a musical wind instrument such as a flute or a whistle. Over time, pipe came to be used to describe various tubular objects, including small tubes used for measuring liquids, and eventually evolved into the modern term pipette.
