Product Overview
The image displays two strips of LaMotte DPD TesTabs Chlorine DPD #1 RAPID Reagent Tablets. Each strip contains 10 tablets individually sealed in blister-style foil packaging. The packaging is designed for easy dispensing, allowing users to press a tablet through the foil directly into a test vial, minimizing handling and potential contamination. The tablets are labeled "DPD 1 RAPID" and include warnings such as "DO NOT EAT".
The LaMotte 6999A-M DPD TesTabs are specifically formulated for testing free chlorine. They come in a convenient blister-style packaging, which simplifies the dispensing process and helps maintain the stability of the reagent.
Setup
Before beginning the test, ensure you have the following:
- LaMotte DPD TesTabs Chlorine DPD #1 RAPID Reagent Tablets
- A clean test vial or sample cell
- A water sample to be tested
- A color comparator or photometer (if quantitative results are desired)
Ensure all equipment is clean and free from contaminants that could interfere with the test results.
Operating Instructions
Follow these steps for accurate free chlorine testing:
- Prepare the Sample: Fill a clean test vial or sample cell with the water sample to be tested. The volume required will depend on your specific testing apparatus (e.g., 10 mL).
- Add the Reagent: Take one LaMotte DPD TesTab Chlorine DPD #1 RAPID Reagent Tablet from its blister packaging. Carefully press the tablet through the foil directly into the water sample in the test vial. Avoid touching the tablet with your fingers to prevent contamination.
- Dissolve the Tablet: Cap the test vial and shake gently until the tablet is completely dissolved. This usually takes a few seconds.
- Observe Color Change: A pink to red color will develop if free chlorine is present. The intensity of the color is proportional to the concentration of free chlorine.
- Read Results: Immediately compare the developed color to a standard color comparator or read the result using a compatible photometer. For accurate results, readings should be taken within one minute of tablet dissolution.
For best results, perform tests in a well-lit area and ensure the water sample temperature is within the recommended range for your testing equipment.
Maintenance
The LaMotte DPD TesTabs themselves require no maintenance. However, proper storage and handling are crucial for maintaining their integrity and accuracy.
- Storage: Store tablets in their original packaging in a cool, dry place, away from direct sunlight and extreme temperatures. The ideal storage temperature is typically between 15°C and 25°C (59°F and 77°F).
- Expiration Date: Always check the expiration date printed on the packaging. Do not use expired tablets, as their accuracy may be compromised.
- Handling: Minimize exposure of tablets to air and moisture before use. Dispense one tablet at a time and reseal any opened packaging if possible.
- Cleaning Equipment: Regularly clean all testing equipment (vials, comparators) with distilled or deionized water to prevent residue buildup and cross-contamination.
