Abstract: Disclosed is a system for use in a flow cytometer for unclogging obstructions in a nozzle from salt crystal formations and clumps of cells or debris. A nozzle system is moved to a docking station so that a nozzle tip is seated in the docking station. Deionized water is pushed through the nozzle in a reverse direction to a waste port so that the nozzle is flushed. The nozzle system can remain in the docked position during nonuse so that salt crystals do not form in or on the nozzle.
