Lamotte 6999A-H Free Chlorine Reagent Refill 0.2-3.0 ppm

Free Chlorine Reagent Refill

This Lamotte 6999A-H refill supplies DPD 1 tablets for colorimetric determination of free chlorine in water samples. The concentration range covers 0.2 to 3.0 ppm, making it suitable for routine monitoring of drinking water, pools or industrial process streams. Each tablet is sealed in blister-style foil packaging that lets the user press a single dose directly into a small vial without handling the chemical. The product is intended for environmental and mechanical test applications where reliable chlorine measurement is required.

Sustained Testing Performance

Under repeated daily use the foil blister protects each tablet from moisture and light, preserving reagent stability over the full testing cycle. Consistent tablet weight and dissolution rate maintain colour development repeatability across the 0.2 to 3.0 ppm range, so calibration remains valid from the first test to the last in the pack. No degradation in colour intensity is observed when tablets are dispensed sequentially during extended monitoring sessions. The packaging format also reduces spillage risk during high-throughput workflows.

Compatibility Check Before Ordering

Verify that your colorimeter or photometer accepts DPD 1 chemistry for free chlorine and is calibrated for the 0.2 to 3.0 ppm range. Confirm the instrument uses a vial size that matches the tablet dimensions supplied in this refill. Ensure your standard operating procedure specifies free chlorine rather than total chlorine, because this reagent is formulated for the free fraction only. No additional hardware or software versions are referenced in the product data.
