A flow cytometry system for sorting cells, in particular sperm, is disclosed. The system includes a nozzle assembly (10) which produces a stream (36) having a sheath fluid (14)surrounding a sample fluid. Particles within the stream are interrogated with electromagnetic radiation and the detected signals (130, 134) are analysed to arrive at a sort decision. The particles in the stream can then be separated downstream. The system also includes a seating element (102) to accurately locate the nozzle (10). |
