What is a Single Channel Variable Volume Micropipette?

A single channel micropipette is a laboratory instrument used to aspirate and dispense liquids in microliter (µl) volumes. The term variable volume means that the user can adjust the volume according to their requirement within a specified range.

Example Volume Ranges:

• 0.1–2 µl
• 2–20 µl
• 20–200 µl
• 100–1000 µl

These micropipettes are widely used for precise liquid handling in scientific experiments.

Working Principle of Micropipette

The working principle of a micropipette is based on the air displacement mechanism.

How it works:

1. Pressing the plunger creates a vacuum.
2. When released, liquid is drawn into the tip.
3. Pressing again dispenses the liquid.

This ensures accurate and controlled liquid transfer.
