CHEMetrics announces the release of a new Vacu-vials test kit which employs the Direct Nesslerization method to measure ammonia in drinking water, clean surface water, good-quality nitrified wastewater effluent, and seawater. The new K-1513 instrumental test kit offers an extended shelf-life advantage over the K-1503 and K-1523 Nessler ammonia Vacu-vials test kits (K-1503 and K-1523 were discontinued in Summer 2024). K-1513 is offered as an alternative to these kits when a longer shelf life is desirable and refrigerated storage is not an option. Table 1 provides shelf-life and other key product definition comparison information.
This test kit can be used to measure the concentration of ammonia in seawater by using the A-1503 Accessory Solution Pack sold separately.
The K-1513 Vacu-vials Ammonia Test Kit comes in a cardboard box and contains everything needed to perform 30 tests: thirty ampoules, Stabilizer Solution, 25 mL sample cup, 3-mL syringe, ampoule blank, and instructions. 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.
