When selecting a wash nozzle for a compact refractometer, take into account both the wash medium and the flow cell model: flow cells with larger pipe diameters need longer wash nozzles. The following figure shows a wash nozzle for a flow cell and gives the measurements and part numbers for each nozzle type.
| For more information on flow cells, see PR‑23‑AC mounting specifications. |
The following table lists wash nozzles according to wash medium and refractometer model for probe refractometers.
| PR23‑AP | PR‑23‑GP | |
