Crystal handling at low temperatures

The cooling of a crystal in combination with the use of a protecting oil facilitates the handling and transfer to a diffractometer of even very sensitive material. The method is explained and the required device is described in this work. Basic advantages of the technique are simplicity and freedom of access to the sample without the need for sophisticated glassware. Therefore, this technique, suitable for crystal manipulation in the temperature range between room temperature and 193 K, is much more efficient than those involving the use of capillaries.
