Abstract
A method of manufacturing a nozzle assembly may include the step of over molding a nozzle housing, or a portion of a nozzle housing, onto at least one nozzle component, such as an injection tube. Nozzle assemblies and flow cytometers incorporating nozzle assemblies may include any combination of straight smooth injection tubes, improved features for securing a nozzle assembly, improved features for debubbilng a nozzle assembly, and aggressive orienting geometries. A method of sorting cells may include the step of magnetically coupling a nozzle assembly with a flow cytometer.
Claims17
A nozzle assembly comprising:
- a) a nozzle housing enclosing a nozzle cavity;
- b) an injection tube having a sample outlet disposed within the nozzle cavity, wherein the interior geometry of the nozzle cavity at the sample outlet of the injection tube comprises an elliptical cross section having a major axis and a minor axis, where the major axis is at least three times the length of the minor axis;
- d) one or more sheath inlets in fluid communication with the nozzle cavity;
- and
- e) a nozzle exit orifice downstream of the sample outlet.
