Abstract
A pipette tip extension attachable to a pipette tip is disclosed. The pipette tip extension has a proximal end, a distal end, and an exterior wall extending between the proximal end and the distal end. The exterior wall has an outer side and an inner side and forms at the proximal end a reception aperture for inserting a pipette tip. The pipette tip extension further has a bottom at the distal end, an inner cavity enclosed by the inner side of the exterior wall and the bottom, one or more distance elements arranged at the inner side of the exterior wall and protruding into the inner cavity, and a coating for interacting with a fluid present in a fluid uptake area.

A pipette tip extension attachable to a pipette tip, the pipette tip extension comprising:
- a proximal end, a distal end, and an exterior wall extending between the proximal end and the distal end, the exterior wall having an outer side and an inner side and forming at the proximal end a reception aperture for inserting a pipette tip,
- a bottom at the distal end,
- an inner cavity enclosed by the inner side of the exterior wall and the bottom,
- one or more distance elements arranged at the inner side of the exterior wall and protruding into the inner cavity, the distance elements being dimensioned to establish a fluid uptake area adjacent to the inner side of the exterior wall and the bottom, the fluid uptake area extending from the bottom up to the reception aperture and being in fluid connection with the surrounding atmosphere at the reception aperture, and
- a coating facing towards said fluid uptake area.

An assembly comprising:
- a pipette tip for aspirating and/or dispensing a liquid,
- a pipette tip extension attached to the pipette tip, the pipette tip extension comprising:
- a proximal end, a distal end, and an exterior wall extending between the proximal end and the distal end, the exterior wall having an outer side and an inner side and forming at the proximal end a reception aperture for inserting the pipette tip,
- a bottom at the distal end,
- an inner cavity enclosed by the inner side of the exterior wall and the bottom,
- one or more distance elements for spacing apart the pipette tip from the attached pipette tip extension, the one or more distance elements being dimensioned to establish a fluid uptake area adjacent to the inner side of the exterior wall, the bottom and the inserted pipette tip, the fluid uptake area extending from the bottom up to the reception aperture and being in fluid connection with the surrounding atmosphere at the reception aperture, and
- a coating for interacting with a fluid present in the fluid uptake area.
