FILLING 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 to adequately fi ll the disk.
1. Fill the included syringe with the water sample.
Then, locate the fi ll hole on the disk and slowly,
with even pressure, begin to fi ll the disk with the
syringe held vertically. The sample water will fi ll
the chambers between the baf fl es in a counter-
clockwise order. Each chamber 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 over fi ll the disk. If the disk is over fi lled,
sample water will fl ow out of the over fl ow hole in
the center of the disk. If this happens, be sure to
dry the disk completely before running 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.
Underfilled
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 the
included lint-free wipe. The disk should be handled
on the edges only. The disk should be fi lled and
used within 10 minutes. They cannot be fi lled
ahead of time. Refer to Step 4 under the TESTING
section for next steps.
