Methods and apparatus for removable nozzle with cam latch engagement in flow cytometers

A method for a flow cell subassembly, the method comprising:

• installing a carriage assembly to a flow cell, the carriage assembly including a carriage plate and a linear bearing, wherein a nozzle mount for receiving a nozzle assembly is coupled to the carriage plate and a cuvette is coupled to the flow cell;
• performing a first engagement test between a first nozzle of a first test nozzle assembly and a cuvette to make a first observation of engagement along a first angle;
• and
• based on the first observation of engagement, adjusting angular orientation (yaw) of a carriage plate with respect to a linear bearing by clockwise or counterclockwise rotation to adjust the engagement between nozzles and the cuvette in a first dimension.

• performing a second engagement test between a second nozzle of a second test nozzle assembly and the cuvette to make a second observation of engagement along a second angle differing from the first angle;
• performing a third engagement test between a third nozzle of a third test nozzle assembly and the cuvette to make a third observation of engagement along a third angle differing from the first and second angles;
• and
• performing a fourth engagement test between a fourth nozzle of a fourth test nozzle assembly and the cuvette to make a fourth observation of engagement along a fourth angle differing from the first, second, and third angles.
