When you think of a laboratory, the image of someone in a white coat carefully measuring liquids is likely one of the first things that comes to mind. And at the heart of this process? The humble pipette.
Whether you're a student just stepping into the world of science, a lab technician, or simply curious about lab tools, this guide will walk you through everything you need to know about pipettes.
What Exactly is a Pipette?
A pipette is a laboratory instrument used to transport a measured volume of liquid, often in microliters (µL) or milliliters (mL). It ensures precision and consistency, especially when working with small quantities.
Think of it as a scientific eyedropper – but way more accurate.
The Main Types of Pipettes
There are several types of pipettes designed for specific tasks. Here are the most common:
1. Single-Channel Pipettes
Used for transferring liquid one sample at a time.
Ideal for basic lab work.
2. Multi-Channel Pipettes
Designed to transfer multiple samples at once (typically 8 or 12 channels).
Perfect for plate-based experiments like ELISA or PCR.
3. Electronic Pipettes
Automate liquid handling.
Improve accuracy, reduce hand fatigue, and store pipetting protocols.
4. Glass Pipettes (Graduated/Volumetric)
More traditional.
Common in chemistry and academic labs.
5. Micropipettes
Handle volumes less than 1 mL.
The go-to tool for molecular biology and biochemistry labs.
Common Applications of Pipettes
Pipettes are essential in many scientific settings, including:
・Cell culture: Adding or removing media.
・Molecular biology: PCR setup, DNA/RNA extraction.
・Pharmaceutical research: Compound handling.
・Clinical labs: Diagnostics and sample preparation.
Basically, if accuracy and reproducibility matter, a pipette is involved.
How to Use a Pipette (Basic Steps)
1.Attach a tip: Always use a clean, compatible pipette tip.
2.Press the plunger to the first stop.
3.Immerse the tip in the liquid.
4.Slowly release the plunger to draw liquid.
5.Move to the destination container.
6.Press to the second stop to dispense.
7.Eject the tip.
Tip: Avoid air bubbles, and always pre-wet tips when working with very small volumes.
