Notes:
1. Mount cell and flow chamber horizontally as shown above with flow exit up to eliminate
possible air gap around cell body.
2. If cell and flow chamber must be mounted vertically, attach a short length of tubing to flow
exit as shown below and form a trap to ensure filling of flow chamber, especially at low flow.
