Single Channel Pipettes
Single-channel pipettes are laboratory instruments used for accurately measuring and transferring small volumes of liquid. They are widely used in various scientific and medical applications, including molecular biology, biochemistry, microbiology, and analytical chemistry. Here are key features and information about single-channel pipettes:
-
Principle of Operation:
- Single-channel pipettes operate based on the air displacement principle. A plunger controls the volume of air in the pipette, and when the plunger is depressed and released, the liquid is aspirated into the disposable tip.
