What is the primary use of a volumetric pipette?

A volumetric pipette is specifically designed for measuring and delivering a fixed volume of liquid with a high degree of accuracy and precision. Its design typically features a long, narrow neck and a bulb in the middle, which allows for precise liquid measurement and transfer. This makes it especially useful in laboratory settings where exact volumes are crucial for experiments, such as in quantitative chemical analyses.

Volumetric pipettes are calibrated for a single volume, which means they provide the same accurate measurement every time you use that specific pipette. This characteristic distinguishes them from other types of pipettes that may not offer the same level of precision.

While there are other pipettes designed for different purposes, such as measuring small amounts of liquid or transporting substances, the key feature of a volumetric pipette is its ability to deliver a specific volume of liquid reliably. This reliability is critical in many scientific and clinical applications where exact measurements can significantly impact results.
