ABSTRACT:
A crystallographic observation apparatus for the observation of behavior of crystals under pressure and for the measurement of the crystallization pressure and pressure of fusion of substances. The apparatus comprises a pressure chamber having a cavity and provided with a transparent observation window or windows, a pressurizing device for pressurizing the cavity of the pressure vessel, and small, entirely or partly transparent, entirely or partly elastic sample containing means for containing a sample, provided within the cavity of the pressure vessel. The sample can easily be changed for another sample simply by changing the sample containing means containing the former sample for another sample containing means containing the latter sample, or the apparatus can easily be cleaned after the completion of observation of a sample for the observation of the next sample, simply by washing the sample containing means. Since the sample is contained in the small sample containing means instead of filling up the cavity of the pressure vessel and the associated piping, the apparatus requires only a small amount of sample for observation. Direct observation of the behavior of the sample under varying pressure visually, a microscope or a combination of image pickup means and display means enables the accurate measurement of the crystallization pressure and pressure of fusion of the sample.
