TNTplus bar-coded vials help to reduce errors in chemical water analysis. Reduce operator-to-operator variability with these easy-to-use chemical reagents.

For determination of Reactive (ortho) and Total Phosphorus (phosphate) by the Ascorbic Acid method. The innovative vial and reagent delivery makes tests easier to use than powder pillows or liquid reagents and significantly reduces spillage or contamination risk.

Switch to simpler, more accuracte nitrate testing with Hach TNTplus® reagents. USEPA approved for compliance monitoring under the Safe Drinking Water Act. The innovative vial and reagent delivery makes tests easier to use than powder pillows or liquid reagents and significantly reduces spillage or contamination risk.

Reduced errors – Automatic method detection with bar-coded vials. Scratched, flawed, or dirty glassware becomes non-issue as instrument averages 10 readings and rejects outliers. Safe handling – Innovative vial and reagent delivery significantly reduces spillage or contamination risk.

The TNTplus system gives you maximum accuracy, precision and repeatability, while minimizing the opportunity for errors. Vials feature freeze-dried reagent integrated into a sealed cap. A unique barcode on each vial is automatically read by Hach spectrophotometers to identify the appropriate method and take the measurement.

The TNTplus® COD vials are designed to measure COD values in an efficient and accurate process

25 Total Alkalinity reagent vials per box. The innovative vial and reagent delivery makes tests easier to use than powder pillows or liquid reagents and significantly reduces spillage or contamination risk.

Scope and application: For surface water, municipal and industrial wastewater. The pH of the water sample must be between pH 4–8. The temperature of the water sample and reagents must be between 20–23 °C (68–73.4 °F). In case of not working at the correct recommended temperature an incorrect result may be obtained.

Scope and application: For wastewater and process waters. Storage temperature: 15–25 °C (59–77 °F) Protect against light. The temperature of the water sample and reagents must be between 15–25 °C (59–77 °F). Digestion is required. Replace the sample with deionized water in the test procedure to determine the reagent blank value.
