AquaPhoenix Ammonia Test Kit: CHEMetrics, 0-60 & 60-600 ppm - K-1510A

K-1510A Ammonia Test Kit: CHEMetrics, 0-60 & 60-600 ppm by AquaPhoenix

Kit comes in a plastic case and contains everything needed to perform 30 tests (except distilled water): Refill, Low and High Range Comparators, dilutor snapper cup, micro test tube, and instructions. Shelf-life: Although the Nessler reagent is stable, its high alkali content attacks the glass ampoule. The resulting precipitate interferes with color comparison. The refill has a 5-month shelf life when stored in the dark and at room temperature. This shelf life can be extended by 18 months if the refill is refrigerated.
