The described High Temperature Heater Accessory for the Digital Instruments MultiMode AFM meets the strong demand for AFM measurements at elevated temperatures. The accessory accommodates several new features: probe heater, water-cooled scanner and environmental control for ensuring stable imaging of samples at temperatures up to 250ºC. The practical examples selected for this work demonstrate the capabilities of high temperature AFM studies with this accessory. Several other applications, which were accomplished using different prototypes of the heating stage, were reported earlier We believe that a broader use of this accessory for AFM applications to polymers will bring invaluable information for academic and industrial researchers.
