Abstract
An apparatus is disclosed for improved high pressure processing of parts and materials with fast cycle time, clean operation, and easy to change pressure vessels. Applications include but are not limited to pressure vessels for critical point drying of MEMS or SEM samples, parts cleaning, supercritical fluid extraction, and aerogel processing. In a specific embodiment, the pressure vessel can operate near or above the critical pressure and temperature of a fluid in the pressure vessel for parts processing. This includes critical point drying of MEMS or SEM samples in an easy to use processing pressure chamber system.
