ABSTRACT:
The present invention is directed to a simultaneous multiple chemical synthesizer comprising a number of reaction vessels wherein each vessel has a filter in the bottom portion thereof, a number of needles wherein each needle is connected to an aspiration injection line of a reaction mixture and a gas supply line in connection with each reaction vessel and each needle does not touch the resin contained in the reaction vessel, a number of arms which are horizontally and vertically movable and hold the respective needles, a bubbling gas line and a waste discharge line in connection with each reaction vessel, wherein each line is connected to the bottom portion of each reaction vessel, a number of purging means which move synchronously with said waste discharge lines, and means for washing the portions of the needles and purge means which contact with the reaction reagents.
