## Abstract

The present invention comprises device (10) which maintains a modified atmospheric pressure within, uses evaporation and condensation by means of heated or cooled fluid jackets and radiators to move and clean washing fluid and fans to increase and decrease the pressure of the gaseous washing fluid in a manner which causes liquid washing fluid to flow laminar within the extraction chamber. The present invention comprises a modular extraction chamber (42) which when fitted to the device (10) is in permanent communication with a boiling chamber (27) and a condensation chamber (33). These chambers are intermittently in communication with an evaporation chamber (12) and a corresponding clean solvent holding chamber (20). The evaporation chamber and the clean solvent holding tank may, upon completion of the extraction cycle sequester the pressurized washing fluid while the rest of the system is depressurized allowing for quick changeover of source material.
