BAL-TEC CRITICAL POINT DRYER
OPERATING INSTRUCTIONS | MANUAL
Critical Point Drying (CPD) utilizes increasing the pressure and temperature of the specimen and by that drying the sample without crossing a phase boundary. This is possible because once the critical point has been passed, the density of the "liquid" and the density of the "gas" are the same. The critical point for water is 228,5 bar and 374°C. The samples are first treated in a suitable transitional fluid such as CO2whose critical point of 73,8 bar and 31°C is considerably more advantageous (lower pressure and temperature).
