Abstract: An analyzer having an inner chassis surrounded by a housing includes sample and dilution probes, a mixing housing including first and second mixing chambers, a flow cytometer including a flow cell, and sample and sheath pumps configured to perform first and second pluralities of tasks, respectively. The first plurality of tasks includes: aspirating sample into the sample probe, dispensing sample from the sample probe into the first and second mixing chambers, delivering first sample-dilution fluid mixture to the flow cell, and delivering second sample-dilution fluid mixture to the flow cell. The second plurality of tasks includes: dispensing sheath to the flow cell in cooperation with the delivery of the first sample-dilution fluid mixture to the flow cell, and dispensing sheath to the flow cell in cooperation with the delivery of the second sample-dilution fluid mixture to the flow cell.

Abstract: A signaling assembly is described and which includes a semitransparent substrate, a light emitting assembly which is disposed in spaced relationship relative to the semitransparent substrate and which when energized emits electromagnetic radiation; and an opaque light orientation assembly which is positioned adjacent to the semitransparent substrate and which permits electromagnetic radiation to pass through the semitransparent substrate at an oblique orientation.
