An inexpensive automatically operated device for the flash annealing of crystals of macromolecules

A small, inexpensive and automatically operated device for the flash annealing of crystals of macromolecules is presented. Operation of the device is completely integrated within the ESRF beamline control graphical user interface for macromolecular crystallography experiments, mxCuBE, and the device can thus be controlled either from the beamline control cabin or by users accessing the beamline remotely.
