Taylor comparators offer systems for colorimetrically determining solute levels in industrial, natural, and recreational waters. In each test, a liquid sample is treated with reagents causing a color to develop. The treated sample is then placed in the comparator base and compared to the liquid-color standards in the Slide. A color match is made and the concentration of the substance is read from the values on the Slide. The unique Taylor colorimetric system compensates for cloudy or colored samples by using three cells. Two untreated samples are positioned on both sides of the treated sample, providing a more accurate color match.
Potential Interference: Other halogens and oxidized manganese may cause positive interference.

1. Rinse and fill three 5 mL test cells (#4025) or test tubes (#4023) to 5 mL mark with water to be tested.
2. Wipe dry and place in three center slots (holes) of comparator base (#9189 or #9190). Test cells (#4025) must be placed WITH FROSTED SIDE FACING OPERATOR.
3. Using 1.0 mL pipet (#4030), add 0.5 mL R-0600 Orthotolidine to center test cell (test tube). Cap and mix.
4. Wipe dry and place in center slot (hole) of comparator base.
5. Place Slide on comparator base. Match color in center test cell (test tube) with a color standard. The Slide is in proper alignment for a color match when a white line on the Slide is directly above the white line on the comparator base. Record as parts per million (ppm) total chlorine (Cl2 ).
NOTE: If sample color matches or is deeper than highest color standard: Use a chlorine Slide with a higher range.
SHIPS Hazardous Additional Hazardous Shipping Charges will apply: *WARNING: Orthotolidine (R-0600) contains 6.6% hydrochloric acid, a corrosive acid, and 0.1% orthotolidine, a suspected carcinogen.
REAGENT SHELF LIFE
All reagents have a shelf life, whether they are liquids, powders, crystals, tablets, or test-strip pads. If kept dry, powders and crystals are very stable; acids are also long lived. Date of manufacture is not the controlling factor when it comes to shelf life—storage conditions are more important. As with all perishables, reagents are sensitive to environmental influences and will last longer under controlled conditions.
To this end, we recommend:
- Storing reagents at a consistent temperature in the range if 36°–85°F (2°–29°C); extreme temperature fluctuation, say from a refrigerator to a hot car trunk, causes reagents to deteriorate.
- Keeping them out of prolonged direct sunlight. (Note: their brown plastic bottles help protect very light-sensitive reagents.)
- Segregating reagents from containers of treatment chemicals.
- Replacing caps immediately and tightening them carefully so that exposure to air and humidity is limited.
- Avoiding switching bottle caps, placing bottle caps on soiled surfaces, repouring reagents into contaminated containers, or touching test strip pads.
Taylor formulates its reagents to remain effective for at least one year, with only very few exceptions (molybdenum indicator in liquid form is one; after four months old it should be tested against a standard periodically). As a general precaution, replace all reagents more than one year old, or at the beginning of a new testing season
