Abstract
An auto-pipetting apparatus includes a dispensing head with at least one pipetting tip mandrel having an elongated stud body with an insertion end. The at least one pipetting tip mandrel mates with a pipetting tip. A first adjustable seal, disposed on the elongated stud body, and a second adjustable seal, disposed on the elongated stud body, seal the pipetting tip mated to the at least one pipetting tip mandrel. The first adjustable seal defines a snub surface. The snub surface effects a substantially continuous circumferential contact seal with radially impinging contact between the pipetting tip and the at least one pipetting tip mandrel. The second adjustable seal is adjustable between a disengaged position and an engaged position and effects a releasable grip and another substantially continuous circumferential contact seal between the pipetting tip and the at least one pipetting tip mandrel around the pipetting tip.
