4.2.3 Prism wash nozzles
When selecting a wash nozzle for a compact refractometer, take into account both
the wash medium and the flowcell model: flowcells with larger pipe diameters need
longer wash nozzles. Figure 4.7 below shows a wash nozzle for a flowcell and gives
the measurements and part numbers for each nozzle type.
