FILLING: Single-Use Disks
When the syringe is placed in the water sample, and the plunger is
pulled all the way up, the syringe will hold more than enough water
sample to adequately fi ll the disk. Hold the syringe vertically and
insert the tip into the fi ll hole in the disk. Press the plunger slowly and
smoothly to fi ll the disk.
1. Fill the disk using slow, even pressure. The
sample water will fi ll the spaces between
the baffl
es in a counterclockwise order.
Each space will fi ll from the bottom to the
top. Sample water should be added until the
sample water in the fourth chamber fi lls
to the
top
of the chamber slightly past the embossed
fi ll line. It is OK to fi ll slightly past the fi ll line.

2. Do not overfi ll the disk. If the disk is overfi lled,
sample water will fl ow out of the overfl ow
hole in the center of the disk. The disk is not
leaking. Dry the disk and run the test.

3. Do not under fi ll the disk. If the disk is under
fi lled, the reagent chambers will not fi ll entirely
and results will be inaccurate.

4. Do not introduce air bubbles into the disk.
The reagent chambers will not fi ll entirely
and results will be inaccurate. As soon as a
bubble starts to form, pull back on the plunger
to draw the bubble out of the disk. Begin the
fi lling process again.

5. Wet disks should be dried thoroughly with a
lint free wipe. The disk should be handled by
the edges.
6. Disks should be fi lled and used within 10 minutes. They cannot be fi lled ahead of
time.
