Abstract:
An apparatus for filling and cleaning an analytical substrate of the type having microchannels, said microchannels having a plurality of inlet ports and a plurality of anode ports separated by a length of the microchannel, comprising:an arm mounted on the apparatus such that the arm may be raised and lowered; a tube-in-tube assembly having a plurality of tube assembly pressure tubes and a plurality of tube assembly vacuum tubes paired one inside the other; a manifold mounted on said arm upon which said tube-in-tube assembly is mounted, said tube-in-tube assembly allowing a pressurized liquid to be distributed by said manifold into said pressure tubes and a vacuum source to be distributed by said manifold to said vacuum tubes; and an injector mounted on said arm and spaced from said tube-in-tube assembly by a distance substantially corresponding to the length of the microchannel, wherein when said arm is lowered, ends of said pressurized tubes seal over inlet ports on said substrate and said injector also seals over an anode port on said substrate.
