Industrial sample changer

This sample changer allows 30 sample cells to be placed at the same time. The temperature is controlled by Peltier elements and can be varied from 10 to 120 °C in less than 30 minutes. The gas tight sample cells are made of aluminum with nickel coating and windows are high quality thin mica sheets (~25 microns) which can be reused. Both liquid and gel type samples can be contained with aluminium or polycarbonate spacers defining the sample thickness. About 100 cells are available for parallel X-ray measurements, cleaning and sample loading.
