摘要： A method of treating an isolated area of a sample with a liquid is disclosed. The method has the steps of generating an isolated area of a sample by a first fluid reservoir where the first fluid reservoir enclosing a distal end of a second fluid reservoir and the isolated area of the sample being sealed towards the remaining area of the sample, bringing the isolated area of the sample into fluid connection with the second fluid reservoir, dispensing a fluid from the second fluid reservoir into the first fluid reservoir thereby generating a fluid flow on the sample at the isolated area in a first direction, and aspirating the fluid from the first fluid reservoir into the second fluid reservoir thereby generating a fluid flow on the sample at the isolated area in a second direction.

摘要： 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.
