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 also has a bottom at the distal end, an inner cavity enclosed by the inner side of the exterior wall and the bottom, and one or more distance elements arranged at the inner side of the exterior wall and protruding into the inner cavity.

A method of treating a sample in a liquid, the method comprising the following steps:
- providing 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, and 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,
- aspirating a liquid into a pipette tip,
- inserting the pipette tip filled with the liquid into the pipette tip extension, and
- dispensing the liquid into the fluid uptake area of the pipette tip extension.
