An automated system for mounting and dismounting pre-frozen crystals has been developed at the Stanford Synchrotron Radiation Laboratory (SSRL).  It is based on a small industrial robot and compact cylindrical cassettes, each holding up to 96 crystals mounted on Hampton Research sample pins. For easy shipping and storage, the cassette fits inside several popular dry-shippers and long-term storage Dewars. A dispensing Dewar holds up to three cassettes in liquid nitrogen adjacent to the beamline goniometer. The robot uses a permanent magnet tool to extract samples from, and insert samples into a cassette, and a cryo-tong tool to transfer them to and from the beamline goniometer.  The system is shown below as installed at A) SSRL BL9-2, B) NSRRC 13C1, and C) the Photon Factory (SBRC) AR BL12.
