5.2 Flow-Cell Kits (Low Pressure)<br />
The Low Pressure Flow-Cell systems (manual or automated kits) use an<br />
innovative sample cell design* with a baffled inlet and dual outlets that minimize<br />
accumulation of entrapped air bubbles and heavy solid particles in the cell (see<br />
Figure 8). The glass cell is threaded on both ends to accommodate plastic end<br />
caps. The cell has an approximate volume of 22 mL when assembled. The parts<br />
disassemble easily for thorough cleaning.<br />

Sample is introduced into the top of the cell (see Figure 9). A baffle deflects<br />
the incoming sample to the side wall of the cell minimizing turbulence in the<br />
light path.<br />
Sample is discharged from top and bottom outlets. The top outlet collects and<br />
expels air bubbles and particles that tend to float. The conical-shaped bottom<br />
outlet collects settleable solids; water discharged from the bottom outlet carries<br />
the settled solids out of the cell. This novel, dual-outlet design eliminates dead<br />
volume in the cell to provide rapid, thorough flushing of the cell from one sample<br />
to the next.<br />
