Functional principle of Eppendorf pipette

Research series pipettes are piston-driven pipettes, whose operation is based on the principle of air discharge. Research series pipettes include fixed volume, continuously adjustable, eight-channel and twelve-channel pipettes, and the multi-channel pipette range is also continuously adjustable. All models of pipettes have an independent back button. Each channel of the multichannel pipette has an independent piston, so it can be used with less than 8 or 12 nozzles. The lower half of the eight-channel and twelve-channel pipettes are interchangeable, with the same range.
