Abstract:
Apparatus for parallel processing of multiple reaction mixtures, said apparatus comprising a reactor having an exterior surface, one or more vessels in the reactor for holding said reaction mixtures, each vessel having a central longitudinal axis, a cannula having a longitudinal axis, a distal end, and a port generally adjacent said distal end for transfer of said reaction material to or from the cannula, one or more cannula passages in the reactor extending between said exterior surface of the reactor and said one or more vessels, the one or more cannula passages being adapted for insertion of the cannula through a selected cannula passage and into a respective vessel, and for withdrawal of the cannula from the selected cannula passage and respective vessel, and a sealing mechanism in each cannula passage for sealing against leakage of gas therepast when the cannula is inserted into or withdrawn from the selected cannula passage, wherein said sealing mechanism comprises a valve movable between a closed position for closing the cannula passage and an open position permitting movement of the cannula past the valve, and a seal in the passage sealingly engageable with the cannula when the valve is in its open position.
Abstract:
A method of processing reaction mixtures in parallel, comprising: forming chemical reaction mixtures in a plurality of reactor vessels of a parallel reactor apparatus said apparatus comprising sensors for providing measured values relating to chemical reactions in said reactor vessels, and a processor for receiving data relating to said measured values; sealing the reaction mixture in each reactor vessel against fluid communication with the other vessels and at a pressure different than ambient pressure; injecting a fluid into at least one of the reactor vessels while the reaction mixture in said at least one vessel is sealed and at a pressure different than ambient pressure; agitating the reaction mixtures for at least a portion of the sealing step; and using the processor to receive said data relating to said measured values of the chemical reactions in said reactor vessels.
Abstract:
A reactor control system for monitoring and controlling parallel chemical reactions during which sensors provide measured values relating to one or more properties of parallel reactions occurring in a plurality of reactor vessels of a parallel reactor, the parallel reactions being performed under conditions defined by one or more reaction parameters, said system comprising (a) a user interface operable to selectively display a representation of measured values, or experimental variables calculated from the measured values, associated with the contents of each of the plurality of reactor vessels and a detailed data representation of the received measured values, or experimental variables calculated from the measured values, for an individual one of the plurality of reactor vessels according to operator input, the user interface being further operable to receive operator input modifying one or more of the reaction parameters associated with one or more of the plurality of reactor vessels during the course of the parallel reactions, and (b) a system control module for controlling the parallel reactions, the system control module being operable to modify the one or more of the reaction parameters according to the received operator input during the course of the parallel chemical reactions.
