Vacuum system for measurement of organic materials

This paper deals with the vacuum system developed for controlled measurement of organic materials. The system allows correct measurement of various organic materials under precisely defined conditions. In addition, this laboratory apparatus provides possibility to measure the materials at the vacuum level of 1·10⁻⁴ mbar or also at specific concentration of different gases. At the defined atmosphere, it is possible to set up the tested sample temperature in the range of −30 °C to 150 °C. The principle of temperature regulation, a thorough description of the system and its features will be discussed in more detail.
