Abstract

A fluorescence microscopy sequencer comprises a fluid transport subsystem in which reagents are pumped through a series of multi-port valves to a mixer or one or more flow cells, or directly into the flow cell(s). The one or more multi-port valves can be mounted upon a fluids manifold having syringe tubes mounted on the opposite side. Mounted on a movable support, the manifold may be brought into and out of fluid communication with a storage block comprising the plurality of reagents. In another embodiment, the sequencer comprises a beamsplitter indexer that facilitates the quick and reliable switching of filter cubes through use of a stepper motor. In yet another embodiment, a motion control system is provided in which an inertial reference is interposed between and directly coupled to a first and second axis of control, thereby minimizing any low structural resonant frequencies and enabling high performance (high frequency response) motion control.
