Abstract: Pipette tip coupler and a disposable pipette tip for a pipette device comprises a stepped coupler shoulder complementary to an axially stepped pipette tip shoulder; a plurality of circumferentially disposed elements or segments carried by the coupler at a location superior to the coupler shoulder; and a distal elastomeric element carried by the coupler at a location distal to the coupler shoulder wherein the plurality of elements or segments have a circumferential, radially translated state that provides an abutment with a first working surface formed in the interior surface of the tip while compressing the distal elastomeric element into sealing abutment with a second working surface formed in the interior surface of the tip and while abutting the proximally facing axial stop surface of the tip with the distally facing axial stop surface of the coupler to define an axial coupling position of the pipette tip on the pipette device.

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 shank, a coupler body distal to the shank, a distal stem and distal end plate distal to the coupler body, a proximal elastomeric element disposed around the shank, a distal elastomeric element disposed around the distal stem, and a coupler stop shoulder surface between the proximal elastomeric element and distal elastomeric element. When a pipette tip is mounted on the pipette tip coupler, the proximal elastomeric element abuts the interior surface of the pipette tip for securing the pipette tip to the coupler, and the distal elastomeric element abuts the interior surface of the pipette tip to form a seal between the coupler and the pipette tip.

Abstract: Pipette tip couplers, pipette tips, coupler and tip combinations, and methods for coupling and decoupling a pipette tip to or from, respectively, a pipette tip coupler mounted on a pipette device. The pipette tip couplers include an elastomeric element, an annular crown shaped raceway, and a coupler stop shoulder surface. The pipette tips include a groove in a first cylindrical section, a second cylindrical section, a tip stop shoulder surface at the interface of the first and second cylindrical sections, a third cylindrical section, a sealing seat surface at the interface of the second and third cylindrical sections, and a fourth section adjacent to the third cylindrical section. When the pipette tip is mounted on the pipette tip coupler, the annular crown shaped raceway abuts the tip groove, the coupler stop shoulder surface abuts the tip stop shoulder surface, and the elastomeric element abuts the sealing seat surface.
