Agilent 8453 Dissolution Testing System Installing and Operating Manual 65
Setting Up 2
Installing Your Multibath System
Connecting Valve System Tubing
You use the multicell transport in the Agilent 8453 spectrophotometer with
the valve-based multibath 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.
You identify the different tubing by the fittings and the lengths.
To connect valve system tubing:
1 Insert the flow cell into position 1 to 4 (depending on the number of the
bath) of the multicell transport in the Agilent 8453 spectrophotometer.
2 Connect the dissolution probes to the valve unit, see Figure 7 on page 33
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.
