Methods for a sorting flow cytometer system are disclosed. The method includes forming a stream of a sample biological fluid; charging the stream of the sample biological fluid with a first voltage having a first voltage polarity; breaking a first charged drop off of the stream, wherein the first charged drop is charged with the first voltage; dropping the first charged drop between a first electrostatic charge plate and a second electrostatic charge plate opposite the first electrostatic charge plate, wherein the first electrostatic charge plate and the second electrostatic charge plate are positioned on an angle to form a progressively larger gap between each; deflecting the first charged drop off of a center stream path towards the first electrostatic charge plate to drop along a line with a first angle; and orienting a first pivotal scupper to allow the first charged drop to fall into a first test tube.
