ABSTRACT:
A pressure reactor which avoids leakage and prevents sample loss upon depressurization. Leakage is avoided by providing a reaction vessel with a screw-threaded closure member. Loss of sample is prevented by the provision of a vapor trap which collects any liquid or vapor which may include dissolved sample, from escaping upon disassembly i.e. de-pressurization of the reactor. A novel solvent system for use in conjunction with the reactor is also disclosed.
