Ammonia — Vacu-vials Kit
Catalog No.: K-1523*
Range: 0-14.0 ppm
Method: Direct Nesslerization
Kit K-1523 comes in a cardboard box and contains everything needed to perform 30 tests: thirty ampoules, Stabilizer Solution, 25 mL sample cup, ampoule blank, and instructions.
*Seawater analysis requires A-1501 Stabilizer Solution (sold separately).
This kit requires the use of a CHEMetrics Direct-Readout Photometer or a spectrophotometer capable of accepting a 13 mm diameter round cell. Instrument sold separately.
Shelf life: Although the Nessler reagent is stable, its high alkali content attacks the glass ampoule. The resulting precipitate interferes with color comparison. The Vacu-vials ampoules have a two-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.
