between 7mm and 10mm ( before the dip cell is inserted). The minimum level
relates to approximately 0.7ml of sample.
Do not overfill the cell; as well as overflowing the cuvette once the dip cell is
inserted, this can also produce thermal gradiants within the sample that will
reduce the accuracy of the temperature control.
If necessary tap the cell lightly to dislodge any bubbles that may be caught
between the electrodes.
Folded capillary cell
Fill the cell as described below
.
Prepare the sample in a syringe of
at least 1ml capacity.
.
Place the sample syringe into one
of the sample ports.
.
Slowly inject the sample through
the cell + , checking that all air
bubbles are removed .
If a bubbles forms under the sam-
ple port, pull the syringe plunger
back to draw the bubble into the
syringe body and then reinject.
.
Once sample starts to emerge from
the second sample port, insert a
stopper , .
.
Remove the syringe and replace
with a second
stopper

.
.
No bubbles should be seen within
the clear capillary area of the cell. If
necessary tap the cell lightly to dis-
lodge them. Check that the cell
electrodes are still completely cov-
ered.
.
Remove any liquid that may have
spilt onto the electrodes.

. The stoppers must be fitted before a measurement is performed.
