Working principle of EPPENDORF pipette

pipetteThe working principle of the piston is to achieve liquid suction and discharge through the telescopic movement of the spring. Under the push of the piston, some air is sent out to suck in the liquid using atmospheric pressure, and then the piston pushes the air to discharge the liquid. When using a pipette, operating it in conjunction with the elasticity of the spring can effectively control the speed and force of the pipette.
