An automated instrument for processing a sample includes a first lock configured to move between a locked configuration and an unlocked configuration. The first lock is configured to be engaged with a first movable holding structure in the locked configuration to secure the first holding structure within the automated instrument. The first lock is configured to be disengaged from the first holding structure in the unlocked configuration to allow movement of the first holding structure within the automated instrument. The automated instrument also includes a robotic arm movable within the automated instrument and configured to move the first lock between the locked configuration and the unlocked configuration. The first holding structure is configured to hold a sample processing device and configured to move within the automated instrument when the first lock is in the unlocked configuration. The robotic arm can also be configured to move the sample processing device within the system.
