Abstract: A flow cell subassembly includes a carriage assembly coupled to a flow cell body to selectively engage a nozzle with a base of a cuvette. The carriage assembly includes a linear bearing slidingly engaged with the flow cell body, a tiltable carriage plate coupled to the linear bearing, and a nozzle mount coupled to the tiltable carriage plate. The nozzle mount receives a nozzle assembly with the nozzle. Set screws can adjust pitch angle of the tiltable carriage plate with the linear bearing to adjust engagement between the nozzle and cuvette in a first dimension. To adjust engagement between the nozzle and cuvette in a second dimension, axial play in bolts/screws through the tiltable carriage plate into threaded holes of the linear bearing allow for yaw angle adjustments.

Abstract: A compact sorting flow cytometer system is disclosed. The system includes a fluidics system having a flow cell and a deflection chamber in communication with the flow cell to receive drops in a stream of a sample biological fluid with one or more biological cells or particles and selectively deflect the drops in the stream of the sample biological fluid with the one or more biological cells or particles; and a droplet deposition unit (DDU) system in communication with the deflection chamber to receive the selectively deflected drops in the stream of the sample biological fluid with the one or more biological cells or particles into one or more containers.

Abstract: A collecting system with a magnetically coupled sample mover is provided for flow cytometry and cell sorter systems. The collecting system uses magnets in a driver carriage to control the position of other magnets in a follower carriage. The driver carriage can thereby control the position of the follower carriage without physically touching the follower carriage.
