CHEMets® Dissolved Oxygen Test Kit Refill

Ideal for low  to medium range colorimetric analysis of water quality. Utilize self-filling ampules and vacuum pulls the sample up from a snap cup into the ampule when the tip is broken off. After tilting the ampule several times to mix the sample and reagent and waiting for the color to develop (usually two minutes or less), the analyst quantifies the result using the provided cylindrical comparator (for concentrations ≤1 ppm) or flat comparator (for concentrations ≥1 ppm).
