An analytical laboratory system and method for processing samples is disclosed. A sample container is transported from an input area to a distribution area by a gripper comprising a means for inspecting a tube. An image is captured of the sample container. The image is analyzed to determine a sample container identification. A liquid level of the sample in the sample container is determined. A scheduling system determines a priority for processing the sample container based on the sample container identification. The sample container is transported from the distribution area to a subsequent processing module by the gripper.
