Microwave Assisted Chemical Synthesis Instrument with Controlled Pressure Release

摘要

An instrument is disclosed for carrying out controlled microwave assisted chemical processes, and that is particularly useful for handling relatively small samples. The instrument includes a needle, and a needle seal adjacent the needle and having a shaft coaxial with the needle and in communication with the needle. A pressure transducer is opposite the needle seal from the needle and in communication with the shaft. A housing holds the needle to the needle seal and the needle seal to the transducer. A chamber is formed between the housing and the needle seal. A lateral shaft goes through the needle seal from the coaxial shaft to the chamber in the housing, and a valve is in communication with the chamber.
