Abstract:
Pipette tip couplers, pipette tips, coupler and tip combinations, and methods for coupling and decoupling a pipette tip to or from a pipette tip coupler mounted on a pipette device. The pipette tip couplers include a proximal elastomeric element, a distal elastomeric element, and a coupler stop shoulder surface between the elastomeric elements. The pipette tips include a groove in a first cylindrical section, a second cylindrical section, a pipette tip stop shoulder surface at the interface of the first and second cylindrical sections, a third cylindrical section distal to the second cylindrical section, and a sealing seat surface at the interface of the second and third cylindrical sections. When the pipette tip is mounted on the pipette tip coupler, the proximal elastomeric element abuts the tip groove, the coupler stop shoulder surface abuts the tip stop shoulder surface, and the distal elastomeric element abuts the sealing seat surface.

Claim (Index 1):
1 - A pipette tip comprising:\n a circumscribing sidewall with an open interior passage including an interior surface and extending along a central longitudinal axis of the pipette tip between an open proximal end and an open distal end of the pipette tip; a first section formed in the interior surface of the circumscribing sidewall distal to the open proximal end, the first section comprising:\n a cylindrical upper first portion having a first diameter; \n a cylindrical lower first portion having the first diameter; \n an annular groove interposed between the cylindrical upper first portion and the cylindrical lower first portion; \n a second section comprising a cylindrical surface formed in the interior surface of the circumscribing sidewall distal to the first section, the second section having a second diameter smaller than the first diameter; a stop shoulder surface formed in the interior surface of the circumscribing sidewall at an interface of the first section and the second section; a third section comprising a cylindrical surface formed in the interior surface of the circumscribing sidewall distal to the second section, the third section having a third diameter smaller than the second diameter; a sealing seat formed in the interior surface of the circumscribing sidewall and interposed between the second section and the third section, the sealing seat comprising:\n an upper annular sealing seat surface edge at an interface with the second section; \n a lower annular sealing seat surface edge at an interface with the third section; \n a sealing seat surface interposed between the upper annular sealing seat surface edge and the lower annular sealing seat surface edge; \n wherein the upper annular sealing seat surface edge is greater in diameter than the lower annular sealing seat surface edge; and \n wherein the sealing seat surface comprises a circumferential upwardly facing tooth edge surface; and \n at least one frustoconical section formed in the interior surface of the circumscribing sidewall adjacent to the third section and between the third section and the open distal end.
