<p>An automated synthesizing apparatus which comprises a raw material, reagent and solvent supply unit (6), a reaction unit (7), a purification unit (8) provided with HPCL and CPC, and a freeze-drying unit (9) for freeze-drying a purified product supplied from the purification unit (8). The raw material, reagent and solvent supply unit (6) includes a plurality of reservoirs for containing raw material, reagents and solvents; volumetric tubes and gas-liquid boundary sensors for the quantification of the raw material, reagents and solvents from the reservoirs; flow-lines for supplying the raw material, reagent and solvent from the reservoirs towards subsequent steps; and solenoid valve assemblies disposed on the respective flow-lines for selectively closing and opening such respective flow-lines; and the reaction unit (7) includes a reaction flask device adapted to receive the raw material from the raw material, reagent and solvent supply unit (6); a separation funnel for extracting or washing a product which is transferred from the reaction flask device; a pH adjusting flask for adjusting acidity or basicity of the reaction liquid from the separation funnel; a plurality of reagent reservoirs disposed for adding a predetermined quantity of reagent to the reagent flask device, volumetric tubes and gas-liquid boundary sensors. All of the units, the sensors and the solenoid valve assemblies of each of the units being so connected with a computer (1) that the sequence of operaton thereof can be controlled thereby.</p> |
