Abstract
A compact sorting flow cytometer system is disclosed. The system includes a flow cell and a deflection unit in communication with the flow cell to receive charged drops and uncharged drops in a stream of a sample biological fluid. The deflection unit includes a case having a deflection cone and chamber, a tub with a drain, and a slot in a base. The deflection unit further includes electrostatic charge plates in the cone forming an electrostatic charge field; and first and second pivotal scuppers, and a center non-pivotal collector arranged along a shaft in the tub of the case. Uncharged drops pass the electrostatic charge field undeflected in a center stream path while charged drops are deflected away from it. The pivotal scuppers pivot between positions to direct charged drops into the tub for aspiration or to pass through the slot in the base for collection.
