High pressure and temperature solvent extraction cell

摘要

An extraction cell apparatus (10) for use in elevated pressure and temperature fluid extractions having a pressure resistant vessel (12) forming a cavity (11), and at least one shoulder portion (13) defining an opening (14) communicating with the cavity (11). An insert member (16) is provided engaging the vessel (12) proximate the shoulder portion (13), and a shoulder seal member (17) is positioned proximate the insert member (16). The seal member (17) is positioned for contact with the shoulder portion (13) upon mounting engagement of the insert member (16) with the seal member (17). An end cap (18) is formed for sliding receipt of the insert member (16) therein until an interior surface (19) of the end cap (18) contacts a backside of the seal member (17). An exterior force applied to the end cap (18) in an inwardly direction toward the shoulder portion (13) causing increasing sealing contact between the seal member (17) and the shoulder portion (13).
