A transport tool for transporting a laboratory article using a pipette of a pipetting system, wherein the transport tool at least comprises: a) a first end, which is implemented as a plug-in sleeve to form a releasable plug connection with a receptacle cone of a pipette of the pipetting system, and which comprises an interior, a sleeve axis, and a receptacle opening, wherein the receptacle cone of a pipette of the pipetting system being implemented for plugging on a disposable pipette tip, can be plugged through the receptacle opening into the interior of the plug-in sleeve, and wherein the interior of the plug-in sleeve is configured so that the transport tool can be plugged onto the receptacle cone of the pipette instead of a disposable pipette tip and can also be discarded again from the receptacle cone of this pipette; b) a second end, which is implemented as an article holder, which comprises a holding axis, and for forming a support connection with a laboratory article further comprises: - a flat holding plate, which is arranged at a second end of the transport tool opposite to the plug-in sleeve, and which is provided with at least one holding means, wherein the holding plate is at least approximately perpendicularly to the longitudinal axis of the pipette or the holding axis; and c) a connecting part, which connects the at least one article holder to the plug-in sleeve at its end opposite to the receptacle opening, so that the holding axis of the at least one article holder and the sleeve axis of the plug-in sleeve are arranged coaxially or axially-parallel to one another, wherein the holding plate comprises as holding means an adhesive means with which the transport tool may form a load-bearing adhesive bond with a flat, at least approximately horizontally surface of a laboratory article or wherein the holding plate comprises as holding means a flatly acting magnetic means with which the transport tool may form a load-bearing magnetic connection to a flat, at least approximately horizontally surface of a laboratory article wherein the laboratory article comprising the at least approximately horizontally surface comprises at least one flat, at least approximately horizontal surface and is selected from a group which comprises microplate covers, covers of reagent containers or reagent troughs, and covers for covering dust-sensitive gels. a) a first end, which is implemented as a plug-in sleeve to form a releasable plug connection with a receptacle cone of a pipette of the pipetting system, and which comprises an interior, a sleeve axis, and a receptacle opening, wherein the receptacle cone of a pipette of the pipetting system being implemented for plugging on a disposable pipette tip, can be plugged through the receptacle opening into the interior of the plug-in sleeve, and wherein the interior of the plug-in sleeve is configured so that the transport tool can be plugged onto the receptacle cone of the pipette instead of a disposable pipette tip and can also be discarded again from the receptacle cone of this pipette; b) a second end, which is implemented as an article holder, which comprises a holding axis, and for forming a support connection with a laboratory article further comprises: - a flat holding plate, which is arranged at a second end of the transport tool opposite to the plug-in sleeve, and which is provided with at least one holding means, wherein the holding plate is at least approximately perpendicularly to the longitudinal axis of the pipette or the holding axis; and - a flat holding plate, which is arranged at a second end of the transport tool opposite to the plug-in sleeve, and which is provided with at least one holding means, wherein the holding plate is at least approximately perpendicularly to the longitudinal axis of the pipette or the holding axis; and c) a connecting part, which connects the at least one article holder to the plug-in sleeve at its end opposite to the receptacle opening, so that the holding axis of the at least one article holder and the sleeve axis of the plug-in sleeve are arranged coaxially or axially-parallel to one another, wherein the holding plate comprises as holding means an adhesive means with which the transport tool may form a load-bearing adhesive bond with a flat, at least approximately horizontally surface of a laboratory article or wherein the holding plate comprises as holding means a flatly acting magnetic means with which the transport tool may form a load-bearing magnetic connection to a flat, at least approximately horizontally surface of a laboratory article wherein the laboratory article comprising the at least approximately horizontally surface comprises at least one flat, at least approximately horizontal surface and is selected from a group which comprises microplate covers, covers of reagent containers or reagent troughs, and covers for covering dust-sensitive gels.
