Claim Text:
1. A reactor assembly comprising: a reservoir a reaction chamber; a valve assembly comprising at least one valve, wherein the valve assembly is adapted to selectively provide fluid communication between the reservoir and the reaction chamber and is adapted to withstand pressures of at least 500 psi; a magnet adapted to produce a static magnetic field having a magnitude of at least about 1 mT; and a radiofrequency pulse generator adapted to produce an applied magnetic field; wherein the reservoir, reaction chamber, and valve assembly are non-magnetic and are positioned within the static magnetic field when the magnet is producing the static magnetic field; wherein the reaction chamber is positioned within the applied magnetic field when the radiofrequency pulse generator is producing the applied magnetic field; wherein the at least one valve comprises a housing having an inner wall defining an internal space and a piston assembly positioned within the space and movable relative to the housing between a first position and a second position; wherein the housing comprises a first opening at a first end and a second opening at a second end opposite the first end; wherein the piston assembly translates to the first position in response to a first fluid pressure applied via the first opening; and wherein the piston assembly translates to the second position in response to a second fluid pressure applied via the second opening; and wherein the piston assembly further comprises a first end, a second end, a channel and at least one sealing member on each side of the channel, wherein the application of a net compressive force to the first and second ends causes at least a portion of each sealing member to move towards the inner wall of the housing, thereby preventing or inhibiting fluids from flowing between the sealing member and the inner wall of the housing.
