How to clean and maintain the pipette

The pipette is a working instrument used at high frequency in our daily experiments. Whether its working state is normal, whether its air tightness is good, whether the operating rod is smooth, and whether the inside and outside parts are kept clean all affect the process and results of our experiments. As the saying goes, sharpening the knife will not delay the woodcutter, and general cleaning and maintenance of the commonly used pipette can effectively extend the normal service life of the pipette and improve our use experience.
