1. Add the sample to be tested to the test tube (0608). For a 0.5 mL or

1.0 mL sam ple size, fill the tube to 10 mL with tap wa ter and use the

0.5 mL pipet (0353) or 1.0 mL pipet (0354) to add the appropriate
amount of sample. For sample sizes greater than 1.0 mL, fill the test
tube (0608) to the specified line.

2. Use the 1.0 mL pipet with red tape (NA-0354) to add 1.0 mL of
*Hypochlorite Reagent A (7939). Swirl to mix.

3. Use 0.1g spoon (0699) to add 0.1g *Potassium Iodide Crystals
(6809). Swirl to mix.

4. Fill the Direct Reading Titrator (0377) with Hypochlorite Reagent D
(2790). See Direct Reading Titrator Manual (1649). Insert the
Titrator tip into the center hole of the test tube cap.

5. While gently swirl ing the tube, slowly de press the plunger to ti trate
the sam ple un til the so lu tion changes from brown to col or less and
