Connecting Valve System Tubing - Agilent Technologies 8453 User Manual, Installing And Operating Manual

Connecting Valve System Tubing

You use the standard cell holder in the Agilent 8453 spectrophotometer with
the valve system. The direction of flow for your samples is from the dissolution
vessels through the valve to the flow cell in the cell holder through the pump
tubing to waste.
Short cell fitting
Connects flow cell to
pump (0.5 m)
Colored sheath
Connects dissolution
probe to valve (1.0 m)
Transparent fitting
Connects waste to
pump (1.5 m)
Long cell fitting
Connects flow cell to
valve (1.4 m or 2.2 m)
Figure 17
The valve tubing kit cell fittings are black and the other fittings are
transparent. You identify the different tubing by the fittings, the colored
heat-shrunk sheaths and the lengths.
To connect valve system tubing:
1 Insert the flow cell into the standard cell holder in the Agilent 8453
2 Connect the dissolution probes to the valve unit, see
Agilent 8453 Dissolution Testing System Installing and Operating Manual
Valve Tubing Kit
spectrophotometer.
and Chapter 4, "Using the Valve Unit and Valve-pump Controller". Connect
the 1.5 m pre assembled tubing with colored heat-shrunk sheaths to the
union attached to the dissolution probe. Connect the tubing with colored
heat-shrunk sheaths to the valve inlets.
