The pipette is the most commonly used tool in the laboratory. The experimental teacher's right assistant, the standard use of the pipette is closely related to the accuracy and precision of the experimental results.

Classified according to the physical principle of liquid absorption:

The working principle of the gas piston pipette: through the telescopic movement of the spring, push the piston, remove part of the air, use the atmospheric pressure to suck the liquid, and then push the air to remove the liquid by the piston. It is suitable for pipetting conventional solutions, and the tip is disposable.

Working principle of external piston pipette: through the continuous movement of the piston in the suction head to remove and discharge liquid, the piston and liquid directly contact, no air column, suitable for density, viscosity, liquid different from water, such as volatile Solution, viscous liquid, liquid with a density greater than 2.0 g/mL, etc. The piston and tip are disposable.
