A pipetting device is disclosed. The pipetting device can include a piston with a stepped profile. The piston can be inserted into a barrel and can have at least two seal elements. The pipetting device can operate in a low volume dispense mode and a high volume dispense mode. The pipetting device can allow for high volumes of liquids to be transferred and also provide for the ability to transfer low volumes of liquids with high precision and accuracy without the need for two or more separate pipettor devices.
