gently inverting it several times. Discard the used
sample and repeat the rinsing procedure two more
times.
4. Fill the rinsed vial with the remaining portion
(approximately 10 ml) of the grab sample up to the
mark indicated in the vial. Cap the vial with the
supplied black screw cap.
5. Wipe the vial with the soft, lint-free cloth supplied.
Ensure that the outside of the vial is dry, clean and
free from smudges.
6. Apply a thin film of silicone oil (supplied) on the sample vial (see Figure 9).
7. Wipe with a soft cloth to obtain an even distribution over the entire vial’s
surface.
NOTES:
1. The purpose of oiling the vial is to fill small scratches and to mask the
imperfection in the glass.
2. Do not apply large quantity of oil as this may collect dirt and dust
8. The sample vial is now ready to be inserted into the sample well of the meter for
measurement.
