What Are Pipettes?

Pipettes are standard laboratory tools used in research and development labs in chemistry, food, biomedical, and other industries.

Lab pipettes are used to measure and transfer small quantities of liquid from one container to another.

Pipette Types

Pipettes come in an array of shapes and sizes depending on their intended use. The most common pipette types include:

Volumetric Pipettes

Volumetric pipettes are famed for their precise measurement capabilities. They are available in many sizes, with average volumes of 10, 25, and 50 mL, researchers and lab technicians use them to make lab solutions from a base stock and to prepare a solution for a process known as titration.

Graduated Pipettes

A type of macro pipette characterized for having its volume marked along the tube in increments. They are generally considered to be less accurate than volumetric pipettes.


Micropipettes typically used in chemistry, forensic, biology, pharmaceutical, and drug research labs to measure and transfer minimal quantities of liquid.

Micropipettes use disposable tips to aspire liquids; these tips vary depending on the specific application and need to be changed after every use to avoid cross-contamination.

It’s important to note that micropipette calibration is required every 3-6 months to ensure both its accuracy and precision

Pipettes are widely used in science labs to transfer liquids in milliliter and microliter volumes. Therefore, the importance of accuracy and precision of these instruments cannot be overestimated, as even a minuscule inaccuracy can create a significant error in lab research results.

For pipette calibration to be ISO 8655 complaint, specific environmental conditions including temperature, relative humidity (RH), and barometric pressure must be present. Therefore, you should only entrust your pipette calibration to an ISO 17025 accredited laboratory as the one Allometrics has.
