Instruction Manual TN-100/ T-100

3.2.1 Preparation of Sample Vial

1. Grab liquid with the plastic bottle provided.

2. Obtain a clean and dry sample vial (Figure 7).

3. Take care to handle the sample vial by the top.

4. Rinse the vial with approximately 10 ml of the sample

water, capping the vial with the black screw cap and

gently inverting it several times. Discard the used sample

and repeat the rinsing procedure two more times.

5. 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.

6. Wipe the vial with the soft, lint-free cloth supplied. Ensure that the

outside of the vial is dry, clean and free from smudges.

7. Apply a thin film of silicone oil (supplied) on the sample vial (see Figure

9). 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. You are now ready to place the vial into the meter for measurement.
