Test Tube Capping And De-Capping Apparatus

A capping and de-capping system comprising:

• an array of capping and de-capping grippers coupled to a gripper attachment body and configured to cap and de-cap tubes in an array of tubes, each gripper configured to engage and retain a cap;
• an array of ejectors coupled to an ejector attachment body, each ejector configured to translate relative to one of the grippers to contact the cap retained by the gripper to eject the cap from the gripper;
• an array of electromotors, each electromotor configured to induce a rotational movement to one of the grippers;
• and
• a translation drive mechanism configured to translate the ejector attachment body and the gripper attachment body relative to each other to effectuate translation of the ejectors relative to the grippers to cause the ejectors to contact the caps retained by the grippers to eject the caps from the grippers.
