摘要:
Methods and apparatus for the generation of chemical libraries are described. The preferred embodiments include a reaction block which uses replaceable reaction chambers supported in the block. Each reaction block is fitted with four sets of 12 reaction chambers, and has fittings that facilitate robotic manipulation. The reaction chambers are preferably fitted with a frit. An s-shaped trap tube snaps into a fitting on the bottom of each reaction chamber. The trap tube runs into a drain tube. The reaction block is fitted with gas (preferably N.sub.2) lines and a septum seal such that gas pressurization empties the reaction chambers into the drain tubes. The drain tubes are arranged so as to mate directly with a standard 96 well microtiter plate for the collection of material. A docking station provides for secure registration of the reaction blocks, and provides for introduction of gases and liquids into the reaction blocks. An inert atmosphere in the reaction block is maintained by a top and (optional) bottom seal. A synthesis support may be introduced into each reaction chamber as a slurry, and the top septum fastened. A needle pipettes reagents from an array of reagent containers into the reaction chambers, and maintains the inert atmosphere. A locking reagent container rack keeps the containers securely in place.

A wash station assembly and method for washing selected samples in a sample containing assembly. The wash station assembly includes a wash station having a frame and a fluid dispensing assembly connected to the frame. The fluid dispensing assembly has a selector valve that is connectable to a plurality of fluid lines and is adjustable to allow only one of the fluids to pass through the selector valve at a time. An array of syringes is coupled to the selector valve and positioned to receive the fluid passing through the selector valve. Each syringe includes a check valve that prevents backflow of fluid or air into the syringe through the pipetting needles. A distribution manifold is connected to the selector valve and receives the fluid passing through the selector valve. The manifold has a plurality of distribution channels coupled to the syringes, to direct the fluid into the syringes. Each distribution channel has a manifold valve therein that prevents backflow of fluid into the manifold from the syringes. An array of pipetting needles is connected to the syringes and is positioned to direct the fluid into the sample containing assembly for washing the samples. The pipetting needles have a radially directed opening in the distal end to direct the fluid radially away from the needle during the dispensing process. A waste management system is connected to the wash station to automatically separate halogenated waste fluids from non-halogenated waste fluids.
