Abstract
A sub-1 μL pipette having a small diameter metal tube that is concentrically located within the tip mounting shaft/portion of the pipette and extends from the distal end thereof by some predetermined distance so as to seal against the interior of a pipette tip that is installed to the tip mounting portion. The use of a small diameter metal tube and sealing of the metal tube against the inner surface of the pipette tip near a distal opening of the pipette tip allows for a minimal ullage volume.
