Abstract: A device for handling core samples during a core sample drilling operation is disclosed. In use the core sample is received in a string of inner tubes within a drill string. The device includes a clamp and a coupling mechanism. The clamp is configured to grip a lower inner tube below a joint between the lower inner tube and an adjacent upper inner tube of the string of inner tubes, with the lower tube received in the drill string and with the joint exposed above a top end of the drill string. The coupling mechanism is configured to engage the upper inner tube and/or the joint and operate to uncouple the upper inner tube from the lower inner tube.
