For some experiments it is interesting to create TEM pictures while the specimen is heated e.g. to observe phase changes. Therefore special heatable holders need to be used. At the Technical Faculty of Kiel a Gatan double tilt heating holder and a Gatan single tilt heating holder are present. With the Gatan double tilt and single tilt heating holders the temperatures up to 1000°C and 1300°C are achievable, respectively.
