What is the volume of a Microcapillary pipette?

Volume of a Microcapillary Pipette

Microcapillary pipettes are precision tools used in laboratories for the handling of very small volumes of liquid, typically in the range of microliters (µL) or even nanoliters (nL). The volume of a microcapillary pipette can vary widely depending on its design and intended use.

Microcapillary pipettes are made from glass or plastic and are designed to draw up and dispense precise volumes of liquid by capillary action. The volume of a microcapillary pipette is determined by its internal diameter and length, as well as the thickness of the capillary wall.

Typical Volumes

• Standard volumes: 0.5 µL, 1 µL, 2 µL, 5 µL, 10 µL, 20 µL, 50 µL, 100 µL, 200 µL, and up to 1000 µL (1 mL).
• Specialized microcapillary pipettes can have volumes as low as a few nanoliters.

It's important to note that the specific volume of a microcapillary pipette is often marked on the pipette itself or specified by the manufacturer. For precise applications, calibration and verification of the pipette's volume are crucial to ensure accurate measurements.

Applications

Microcapillary pipettes are essential in various fields such as molecular biology, chemistry, medicine, and environmental science. They are used for tasks that require the manipulation of small volumes of liquid, including DNA sequencing, drug development, and the preparation of samples for analysis.

In conclusion, the volume of a microcapillary pipette can range from a few nanoliters to several microliters, depending on its design and the requirements of the specific application. These tools are indispensable in the laboratory for the precise handling of small volumes of liquid.
