Patent ID: 7829032

Claim:
A microfluidic system for synthesis of a radiolabeled compound, the system configured to transfer and facilitate the reaction of microliters and/or nanoliters of reagent, the system comprising: a microfluidic synthesis chip configured for conducting batch reactions, the chip comprising; a reaction chamber; an inlet flow channel in communication with the reaction chamber and configured to pass reagent into the reaction chamber, the inlet flow channel having a valve configured to regulate flow to the reaction chamber; and a plurality of outlet channels in communication with the reaction chamber and configured to pass reagent out of the reaction chamber, each channel having a valve configured to close to trap reagent within the reaction chamber during a reaction and release reagent and products when the reaction is complete; and a reagent source comprising at least one reagent, the reagent source in fluid communication with the reaction chamber via the at least one flow channel, wherein the reaction chamber has an area substantially greater than a cross-sectional area of each of the inlet flow channel and the outlet channels.
