PLUNGER FOR LOW-VOLUME SYRINGE PIPETTE

摘要

One or more techniques and/or systems are disclosed for use with a syringe or pipette that may provide improved dispensing of fluids from the syringe or pipette. For example, typical syringes or pipettes can draw in a desired volume of fluid, and subsequently dispense the same volume. As described herein, a device can be configured to draw in a first volume and subsequently dispense the first volume and a second volume of fluid, such that portions of the fluid, such as liquids, that may be retained in the syringe or pipette can be displaces by the second volume.

1. A plunger apparatus for use with a pipette or syringe, comprising:
a shaft configured to selectively engage with a pipette or syringe; a first biasing component disposed on the shaft, and configured to provide a first biasing force between the shaft and the pipette or syringe; a second biasing component disposed on the shaft, and configured to provide a second biasing force between a distal end of the shaft and a collar engaged with the shaft.
