*WARNING: Reagents marked with a * are considered hazardous substances. To view or print a Material Safety Data Sheet (MSDS) for these reagents see MSDS CD or our website. To obtain a printed copy, contact us by e-mail, phone or fax.

To order individual reagents or test kit components, use the specified code number.

NOTE: Read the Direct Reading Titrator Instruction Manual before proceeding. The Titrator is calibrated to resad the Alkalinity test result directly in ppm Calcium Carbonate (CaCO3). Each minor division on the Titrator scale equals 4 ppm.

PHENOLPHTHALEIN (P) AL KA LIN ITY PRO CE DURE

1. Fill test tube (0778) to 5 mL line with sample water.

2. Add 3 drops of *Phenolphthalein Indicator, 1% (2246). Cap and

mix. If no red color develops, the P Alkalinity is zero; proceed to Step

6. Otherwise, proceed to Step 3.

3. Fill the Direct Reading Titrator (0382) with *Alkalinity Titration Reagent B (4493DR). Insert Titrator into center hole of test tube cap.

4. While gently swirling tube, slowly press plunger to titrate until red color disappears. Record test result directly from the Titrator as ppm P Alkalinity as CaCO3. Do not move plunger. Save sample and titrant for Total (T) Alkalinity test.

TO TAL (T) AL KA LIN ITY PROCEDURE

5. Being careful not to move plunger, remove Titrator and cap from test tube.

6. Add 3 drops of Total Alkalinity Indicator (2786) to the sample from Step 4. Cap and mix. Solution should turn green-blue.

7. Reinsert Titrator into cap. While gently swirling the tube, add *Alkalinity Titration Reagent B (4493DR) until green-blue color changes to pink. Read result directly from the Titrator as ppm T Alkalinity as CaCO3.

If only Total Alkalinity is to be tested, perform Steps 1, 6 and 7, using a full Titrator for Step 7.
