Abstract
Multivolume liquid pipettes with nested plunger and vacuum chamber configurations and methods of using such pipettes are disclosed herein. These pipettes typically include a body and a fluid displacement assembly with a small plunger element slideably received within a larger plunger element, each movable within a vacuum chamber for the precise and accurate control of the displacement of fluid, such as air. In turn, this allows for a single device to aspirate and dispense a broad range of liquids in a dynamic, accurate, and precise manner. In addition, the devices disclosed herein may also include a multi-tiered spring-loaded ejection mechanism to allow the user to use and eject pipette tips of different sizes.
