Improved flow cytometer mouthpiece and flow cytometer sample handling procedures (57) Summary
An improved nozzle system for a flow cytometer and enclosed methods has been devised for high efficiency orientation and sorting processes for a flat sample and fragile articles such as horse and gut tissue cells. This improved nozzle system includes a mouthpiece (16) having a new internal surface geometry which both gently accelerates the cells and may include an elliptical-like single-torsion inner surface member within (c) the nozzle, i.e., a single torsional orientation nozzle (6). The elliptical-like, single torsion inner surface element can e.g. (8, 9, 10) have a laminar flow surface and can provide the simplest flow path to apply minimal forces acting in either an acceleration nature or as
