## Abstract

A laboratory sample container carrier cleaning apparatus is provided comprising a revolving device, being adapted to move a sample container carrier supplied to the revolving device along a circular path, and a cleaning device, being adapted to clean the sample container carrier being moved along the circular path.

## Claims

### Claim 1

A laboratory sample container carrier cleaning apparatus, comprising:
a revolving device configured to move a sample container carrier supplied to the revolving device along a circular path;
a cleaning device, configured to clean the sample container carrier being moved along the circular path; and
a driving surface, wherein the revolving device is configured to push the sample container carrier supplied to the revolving device on top of the driving surface along the circular path,
wherein the driving surface comprises at least one opening, and
wherein the cleaning device is adapted to clean a bottom surface of the sample container carrier being placed above the at least one opening, the cleaning device comprising a vacuum pump configured to provide a negative pressure in a volume below the at least one opening.

### Claim 2 (depends on 1)

The laboratory sample container carrier cleaning apparatus according to claim 1, wherein the revolving device comprises a number of pushing cavities configured to receive the sample container carrier to be rotated and configured to push the sample container carrier received along the circular path.

### Claim 3 (depends on 2)

The laboratory sample container carrier cleaning apparatus according to claim 2, wherein each of the number of pushing cavities comprises two side walls,
wherein the side walls rotate around an axis of rotation of the revolving device, and
wherein for each of the number of pushing cavities one of the two side walls pushes the sample container carrier in contact with the one side wall along the circular path.

### Claim 4 (depends on 3)

The laboratory sample container carrier cleaning apparatus according to claim 3, wherein the side walls contact each other along the axis of rotation of the revolving device.

### Claim 5 (depends on 1)

The laboratory sample container carrier cleaning apparatus according to claim 1, wherein a brush is arranged at an edge of a respective side wall facing towards the driving surface.

### Claim 6 (depends on 1)

A laboratory sample distribution system, wherein the laboratory sample distribution system comprises:
a number of sample container carriers, wherein the sample container carriers are adapted to carry one or more sample containers, wherein the sample containers comprise samples to be analyzed,
a transport plane, wherein the transport plane is configured to support the sample container carriers,
drive means, wherein the drive means are configured to move the sample container carriers on top of the transport plane, and
the laboratory sample container carrier cleaning apparatus according to claim 1.

### Claim 7 (depends on 6)

The laboratory sample distribution system according to claim 6, wherein the transport plane is arranged adjacent to the driving surface, and wherein the drive means are adapted to supply the sample container carriers to the revolving device.

### Claim 8 (depends on 6)

The laboratory sample distribution system according to claim 6, wherein each of the sample container carriers comprises at least one magnetically active device, and wherein the drive means comprise a number of electro-magnetic actuators being stationary arranged in rows and columns below the transport plane, the electro-magnetic actuators being adapted to apply a magnetic force to the sample container carriers.

### Claim 9 (depends on 8)

The laboratory sample distribution system according to claim 8, wherein the at least one magnetically active device comprises at least one permanent magnet.

### Claim 10 (depends on 6)

The laboratory sample distribution system according to claim 6, wherein the laboratory sample distribution system further comprises:
a gripping device configured to insert sample containers into the sample container carriers positioned at a hand-over position and/or remove the sample containers from the sample container carriers positioned at the hand-over position, wherein the hand-over position is located on the circular path.
