what does a pipette do

A pipette is a laboratory tool used to measure and transfer small, precise volumes of liquid from one container to another.

What a pipette actually does

In simple terms:

• It sucks up a set amount of liquid (you “aspirate” it) using a partial vacuum created by a plunger or bulb.

• It then dispenses that exact volume into another tube, flask, plate, or well, which is key for reproducible experiments.

Pipettes are especially important when you need accuracy and consistency , like in chemistry, biology, diagnostics, and pharmaceutical labs.

Main types and what they handle

Different pipettes are optimized for different scales and uses:

Type| Typical use case
---|---
Glass (volumetric) pipette| Moves a fixed, very precise volume (e.g., 10 mL) in titrations or standard solutions. 38
Micropipette (adjustable)| Handles microliter (µL) volumes, common in molecular biology and PCR setups. 510
Multichannel pipette| Fills whole rows of microplates at once, used in high‑throughput screening. 48
Pasteur / disposable plastic pipette| Approximate transfers (e.g., moving drops or small volumes where exact precision isn’t critical). 210

Where you’ll see pipettes in action

Across labs and industries, a pipette does things like:

• Preparing serial dilutions and calibration curves.

• Loading reagents, buffers, or samples into cuvettes, microplates, or test tubes.

• Handling DNA, PCR mixes, or cell‑culture media in modern life‑science workflows.

So if you picture a scientist in a coat very carefully “squeezing a button on a pen‑like tool to move clear liquid,” that’s basically what a pipette does: measure and move liquid in controlled, tiny amounts, so experiments actually work the way they’re supposed to.
