A pipette is a common tool used in science laboratories for accurately measuring and transferring small volumes of liquid. Its purpose is to ensure precise and controlled dispensing of liquids during various scientific procedures, such as chemical analyses, sample preparations, and experiments.
The main functions of a pipette include:
1. Measurement: Pipettes are designed to measure and transfer specific volumes of liquids, typically ranging from microliters (µL) to milliliters (mL). They provide a way to precisely control the amount of liquid being dispensed.
2. Accuracy: Pipettes are calibrated to deliver accurate and reproducible volumes. This is crucial in scientific research, where precise measurements are essential for obtaining reliable data and maintaining experimental consistency.
3. Contamination prevention: Pipettes are often used in experiments that require high levels of precision and cleanliness. They help minimize the risk of cross-contamination between samples, as disposable tips or sterile pipettes can be used to handle different liquids or samples.
4. Time efficiency: By providing a quick and efficient way to transfer liquids, pipettes contribute to the overall efficiency of laboratory procedures, reducing the time required for repetitive tasks and allowing scientists to work more efficiently.
Pipettes come in different types, including manual pipettes operated by hand, electronic pipettes that offer increased accuracy and programmable features, and multichannel pipettes that can handle multiple samples simultaneously
