How does an air displacement pipette work?
1. The piston moves to the appropriate position when the volume is set.
2. When the operating button is pressed to the first stop, the piston expels the
same volume of air as indicated on the volume setting.
3. After immersing the tip into the liquid, the operating button is released.
This creates a partial vacuum and the specified volume of liquid is aspirated
into the tip.
4. When the operating button is pressed to the first stop again, the air dispenses
the liquid. To empty the tip completely the operating button is pressed to the
second stop (blow out).
