Figure 3-5. Sample Temperatures Screen
Initially, all vessel positions will display “----“. To record the temperature
of an individual vessel, press the appropriate location in the Vessels
region diagram. The “----“ is replaced by the temperature of the medium in
the vessel.
If a position that has a temperature recorded is pressed again, the value
will toggle back to “----“. Any vessel positions that are not active will beep
when an attempt to record a temperature is made. Pressing the printer
icon will send the recorded values to the printer. Press Close to return to
the Main screen.
3.2.2. AutoTemp - Vessel Temperatures
If the AutoTemp option is installed on the 708-DS dissolution apparatus
with a printer, it is possible to have the initial and final temperatures
documented on the report printout. Vessel temperatures at each sample
time point may also be documented. Specific details regarding enabling of
this option will be discussed in Section 6 of this manual (Method Setup
and Execution...). For any manual or pre-programmed dissolution
method, it is required to allow at least 30 seconds of equilibration time in
the dissolution medium to achieve an accurate temperature reading.
Individual vessel temperatures are displayed at any time by lowering the
manifold. It is important to ensure that the temperature probes are
immersed sufficiently into the dissolution medium (minimum of 2 cm). The
level that the manifold is lowered at any time is dependent on the volume
and the apparatus being used. These settings are programmed from
within the Calibration menu and are explained in detail in Section 5.1.
