USE OF THE OCTA-SLIDE 2 VIEWER
The Octa-Slide 2 Viewer should be held so
non-direct light enters through the back of
the Viewer. Insert the reacted sample into
the top of the Viewer. Slide the Octa-Slide 2
Bar into the Viewer and match the color of
the reaction to the color standards.
WARNING! This set contains chemicals
that may be harmful if misused. Read
cautions on individual containers
carefully. Not to be used by children
except under adult supervision

PROCEDURE
1. Use the 1.0 mL pipet (0354) to add 2 mL of sample water to a 5 mL test tube
(0106).
2. Use water from the Demineralizer Bottle (1151) to fi ll test tube to the 5 mL line.
Cap and mix.
3. Add 5 drops of *Zinc Conditioning Reagent (7361). Cap and mix. Wait one
minute. This reagent will eliminate copper interference and adjust the pH of the
sample water to pH 9. In water samples where the pH is very low, adjust the pH
of the sample to approximately 9 before adding the *Zinc Conditioning Reagent
(7361).
4. Use the 0.5g spoon (0698) to add one level measure of *Zinc Reagent Powder
(7393). Cap and shake for 15 seconds. Do not shake for longer than 15 seconds,
even if some powder remains undissolved. Wait one minute. Do not mix.
5. Immediately, insert the Zinc Octa-Slide 2 Bar (7392-01) into the Octa-Slide 2
Viewer (1101). If reading is darker than 10 ppm standard see procedure for High
Range Readings.
6. Insert the test tube into the Octa-Slide Viewer.
7. Match the sample color to a color standard. Read within 30 seconds. Record as
ppm Zinc.
NOTE: Slight variations in the amount of *Zinc Reagent Powder (7393) added
in Step 4 may cause the intensity, but not the shade, of the color reaction to vary.
Since each color standard exhibits a distinct shade of color, this should not hinder
the ability to get an accurate reading.
HIGHER RANGE READINGS (0-20.0 ppm)
If reading is darker than the 10 ppm color standard repeat test on a diluted sample.
1. Use the 1.0 mL pipet (0354) to add 1 mL of sample water to a test tube (0106).
2. Follow Steps 2 through 7 above. Multiply reading by 2. Record as ppm Zinc.
LOWER RANGE READINGS (0-4.0 ppm)
For more precise measurements between 0 and 4 ppm.
1. Fill test tube (0106) to 5 mL line with sample water.
2. Follow Steps 3 through 7 above. Multiply reading by 0.4. Record results as ppm
Zinc.
