The analysis tool is built to assign information to the petri dish, and in case of a first information assigned to the petri dish the control unit is built to move the first elevator into a carrier position, wherein, as soon as the first elevator reaches the carrier position, the control unit is built to move a substantially flat first plate along the first elevator axis from a first neutral position located in the conveyor plane into a first transfer position. ## Claims ### Claim 1 A system for analyzing and sorting of petri dishes comprising an analysis tool, a control unit configured to communicate with the analysis tool, a first elevator movable along a first elevator axis by the control unit, a conveyor with a conveyor plane substantially rectangular to the first elevator axis, and at least one carrier configured to carry the petri dishes along a carrier axis substantially parallel to the first elevator axis, wherein the analysis tool is configured to analyse the petri dish and to assign information to the petri dish based upon the analysis, the control unit is configured to move the first elevator along a conveyor direction of the conveyor and to move the petri dish by means of the conveyor on the conveyor plane along the conveyor direction from the analysis tool toward a first neutral position for sorting, and in case of information assigned to the petri dish is a first information, the control unit is configured to move the first elevator into a carrier position, which is virtually situated at the point of intersection of the carrier axis with the conveyor plane and reached as soon as the carrier axis and the first elevator axis substantially coincide, wherein, as soon as the first elevator reaches the carrier position, the control unit is configured to move a substantially flat first plate of the first elevator along the first elevator axis, which first plate is configured to receive the petri dish from the conveyor, to move the first plate from the first neutral position located in the conveyor plane into a first transfer position according to the first information, which is reached as soon as the petri dish is being taken over by the at least one carrier. ### Claim 2 (depends on 1) The system according to claim 1, wherein in an installation orientation of the system, as soon as the first elevator reaches the carrier position, the control unit is configured to move the first plate along the first elevator axis in order to move the first plate from the first neutral position upwards into the first transfer position. ### Claim 3 (depends on 1) The system according to claim 1, wherein the first elevator comprises pushing means configured to move the petri dish on the conveyor plane along a pushing axis substantially transversal to the conveyor direction. ### Claim 4 (depends on 3) The system according to claim 3, wherein in case information assigned to the petri dish is a second information, the control unit is configured to move the first elevator into a multi-carrier position, which is reached as soon as a centre of a second plate of a second elevator lies on the pushing axis of the pushing means of the first elevator, wherein, as soon as the first elevator reaches the multi-carrier position, the control unit is configured to control the pushing means to move the petri dish along the pushing axis onto the second plate or onto an upmost petri dish carried by the second plate, which second plate is movable along a second elevator axis by the control unit. ### Claim 5 (depends on 4) The system according to claim 4, wherein the second elevator comprises a sensor configured to communicate with the control unit and to detect the petri dish on the second plate. ### Claim 6 (depends on 4) The system according to claim 4, comprising at least one multi-carrier configured to carry the petri dishes along at least two multi-carrier axes substantially parallel to the second elevator axis, wherein one multi-carrier axis substantially coincides with the second elevator axis. ### Claim 7 (depends on 6) The system according to claim 6, wherein in the installation orientation of the system, the control unit is configured to move the second plate along the second elevator axis from a second neutral position located in the conveyor plane downwards into second transfer positions, which are reached each time a bottom container of the upmost petri dish carried by the second plate levels with the conveyor plane. ### Claim 8 (depends on 6) The system according to claim 6, wherein the at least one multi-carrier is configured to carry the petri dishes along four multi-carrier axes. ### Claim 9 (depends on 6) The system according to claim 6, comprising at least one rotatable platform configured to receive the at least one multi-carrier, wherein the rotatable platform is rotatable around a platform axis by the control unit in order to position the at least two multi-carrier axes in accordance to the second elevator axis. ### Claim 10 (depends on 1) The system according to claim 1 comprising a carrier sensor system configured to communicate with the control unit and to detect the petri dishes carried by the at least one carrier. ### Claim 11 (depends on 1) The system according to claim 1, wherein the conveyor is realized as a conveyor belt driven by a conveyor drive, wherein the conveyor belt is split into two conveyor belts separated by a gap. ### Claim 12 A method for analyzing and sorting of petri dishes with a system comprising an analysis tool, a control unit, a first elevator movable along a first elevator axis, a conveyor, and at least one carrier and at least one multi-carrier, respectively configured to carry the petri dishes, wherein the following steps are processed: analyse and assign information to the petri dish with the analysis tool, based upon the analysis, and communicate this information to the control unit; move the petri dish by means of the conveyor on a conveyor plane along a conveyor direction from the analysis tool toward a first neutral position for sorting; receive the petri dish from the conveyor on a substantially flat first plate of the first elevator; in case information assigned to the petri dish is a first information, move the first elevator along the conveyor direction of the conveyor into a carrier position virtually situated at the point of intersection of a carrier axis with the conveyor plane and, as soon as the first elevator reaches the carrier position, move the first plate along the first elevator axis from the first neutral position into a first transfer position, and take over the petri dish by the carrier. ### Claim 13 (depends on 12) The method according to claim 12, wherein, in an installation orientation of the system, in case of the first information assigned to the petri dish the first plate is moved along the first elevator axis from the first neutral position upwards into the first transfer position. ### Claim 14 (depends on 12) The method according to claim 12, wherein in case information assigned to the petri dish is a second information, the first elevator is moved along the conveyor direction of the conveyor into a multi-carrier position and, as soon as the first elevator reaches the multi-carrier position, the petri dish is moved via pushing means along a pushing axis substantially transversal to the conveyor direction onto a second plate of a second elevator, which second plate is movable along a second elevator axis, or onto an upmost petri dish carried by the second plate.
