In general, pipettes require regular inspection. Regular inspection is mainly to ensure the better accuracy of the pipette and the inspection results. The pipette is a measure-out type, which is greatly affected by the environment and operation. Therefore, when adjusting the range of the pipette, the counterclockwise rotation is used in order to ensure the accuracy of the measurement during the rotation of the knob. Use your index finger and thumb to adjust the knob. If the maximum range is exceeded,...
