Development of SPACE-II for rapid sample exchange at SPring-8 macromolecular crystallography beamlines
A rapid and reliable sample changer, SPACE-II, has been developed at the SPring-8 macromolecular crystallography beamline BL41XU. It enables samples to be exchanged in 16 s, of which its action accounts for only 11 s. Two years of operating SPACE-II demonstrated that the average number of sample exchanges per day was increased by 40% compared with the previous model, and it had an error rate of only 0.089%.
