FAQs
What is the primary use of Lovibond DPD No. 3 tablets?
Lovibond DPD No. 3 tablets are primarily used for the accurate determination of total chlorine in water samples, following the measurement of free chlorine.
How should I store these test tablets?
Store the tablets in their original, unopened aluminium foil blister packaging in a cool, dry place away from direct sunlight and chemical fumes.
Can I use tablets that are past their expiry date?
It is not recommended to use tablets past their expiry date, as their chemical integrity may be compromised, leading to inaccurate test results.
How do I handle the tablets to ensure accuracy?
Handle the tablets carefully, preferably by removing them from the blister pack without touching the tablet surface directly. Use them immediately after removing from the protective foil.
Are these tablets safe to use?
Yes, the tablets are safe to use when handled and applied in accordance with the instructions provided with the product and your testing equipment. Always consult the Material Safety Data Sheet (MSDS) if available.
What is the benefit of the aluminium foil blister packaging?
The aluminium foil blister packaging provides excellent protection against moisture, light, and air, ensuring the stability and accuracy of each individual tablet and offering enhanced user convenience.
How many tablets are in one package?
The package contains 100 DPD No. 3 tablets, organized into 10 strips, with each strip containing 10 tablets.
Troubleshooting
Inconsistent or unexpected test results.
Ensure tablets are within their expiry date. Verify proper storage conditions. Check that the correct tablet type (DPD No. 3) is being used for the intended test and that the water sample is suitable (clear, correct pH if specified by the instrument).
Tablet does not dissolve properly.
Ensure the tablet is placed directly into the water sample and gently swirl or stir as per the instrument's instructions. Avoid crushing the tablet before addition, as this can affect dissolution.
Color development is too faint or too intense.
Confirm the correct tablet dosage and sample volume are used. Ensure adequate reaction time is allowed as per instructions. Re-test if results appear erroneous. The water's chlorine concentration may be outside the optimal range for the reagent; consider diluting the sample if very high, or using a different test if very low.

Setup, Compatibility & Care
Setup:
These test tablets are designed to be used with appropriate water testing equipment, such as Lovibond comparators or spectrophotometers. Follow the specific instructions provided with your testing instrument for sample preparation and tablet addition.
Compatibility:
The DPD No. 3 tablets are formulated for testing chlorine levels in water samples. Ensure your testing kit is compatible with DPD reagents. They are intended for use with clear water samples; turbid or colored samples may require pre-treatment.
