Abstract: A workstation is described for mounting specimens into a cryotransfer holder at cryogenic temperature. The workstation allows rotation about the cryotransfer holder axis to improve access to the sample placement area on the holder and to facilitate easy removal and retrieval of the sample after imaging. The cryotransfer holder includes a cylindrical dewar configured to maintain a constant center of mass about the holder axis regardless of orientation of the dewar.
