GBL® AQUA-ROSA

7013-Hemodialysis Machine Dialysis Water Analysis Kit Colorimetric Titrimetric

Title Description
REF No 7013
Purpose Free chlorine in various waters, pH colorimetric determination, and total hardness determination in low alkalinity waters.
Ingredients A-pH Indicator: Phenol red, ethanol 96%.
B-Chlorine Reagent: O-Tolidine, hydrochloric acid.
C-Buffered Indicator Titrator: Eriochrome black T, ethanol 96%, ethta disodium salt.
Working Principle
Warnings, Precautions, Recommendations Danger. Highly flammable liquid and vapor. May corrode metals. Causes severe skin burns and eye damage. Keep away from heat/sparks/flames/hot surfaces. Store only in the original container. Wear protective gloves/protective clothing/eye protection/face protection. IF SWALLOWED: Rinse your mouth. DO NOT induce vomiting. IF ON SKIN (or hair): Immediately remove all contaminated clothing. Rinse skin with water/shower.
Application Measuring the pH of Water:
1. Take the measuring cup from your kit.
2. Pour the water sample to be tested up to the 10 ml mark.
3. Hold the A-pH Indicator bottle at a 90-degree angle with the dropper opening. Make sure the drops are not air bubbles. Add 2 drops to the sample, close the cap, and stir 2 times.
Measuring Free Chlorine in Water:
1. Take the measuring cup from your kit.
2. Add the water sample to be tested up to the 10 ml mark.
3. Hold the B-Chlor Separator bottle at a 90-degree angle with the dropper opening. Ensure the drops are not air-bubbled. Add 3 drops to the sample, close the cap, and mix thoroughly for 3 turns.
4. Determine the free chlorine content of the water by comparing the color in the container to the chlorine color scale.
Measuring Hardness in Water:
1.Take the measuring cup from your kit.
2.Fill it with the water sample to be tested up to the 5 ml mark.
3.Hold the C-Buffered Indicator Titrator bottle at a 90-degree angle with the dropper opening. Make sure the drops are not air bubbles. Add 1 drop and mix.
4.If a red-pink color appears, continue adding drops from the C-Buffered Indicator Titrator.
5.Stir after each drop.
6.Continue the dropping process until the color turns bluish-green.
7.Stop the titration when the bluish-green color appears.
Theoretical Results
A- The pH color scale is compared with the change in the color of the water sample.
B- The chlorine color scale is compared with the change in the color of the water sample.
C- The number of drops used gives the total hardness of the water sample.
1 drop = 1 AS.
