US Patent 7462323 Apparatus for performing heat-exchanging chemical reactions

An apparatus for controlling the temperature of a reaction mixture contained in a chamber of a reaction vessel comprises a thermal surface for contacting a flexible wall of the chamber and an automated machine for increasing the pressure in the chamber. The pressure increase in the chamber is sufficient to force the flexible wall to conform to the thermal surface for good thermal conductance. The apparatus also includes at least one thermal element for heating or cooling the surface to induce a temperature change within the chamber.
