The lower portion of the suction tube is sealed to a sintered frit filter medium. The suction tube mounts in a reactor block into a reactor vial for receiving chemical components. An inlet channel with a first seal is formed through the block and conveys chemical component materials to the vial, and a suction channel with a second seal, coaxial with the suction tube, is used to remove resultant chemical compound materials therefrom. A pressurized gas channel containing inert gas is formed through the block to intersect the suction channel and the inlet channel.Other References
