Hach® Spectrophotometers paired with TNTplus® vials make expert water analysis simple.

Reduce errors

A unique barcode label on each Hach TNTplus Vial Chemistry is automatically read by the spectrophotometer when used with Hach’s DR3900 Benchtop Spectrophotometer or DR6000™ UV-VIS Spectrophotometer to identify the appropriate method and take the measurement. Dirty, scratched, or flawed glassware is no longer an issue because the instruments average 10 readings and reject outliers.

Lot after Lot - Be Right

Truecal™ with each vial includes the calibration data for each individual lot, reducing variation in results. This allows you to meet reporting standards and to perform proficiency testing with higher confidence.

Documented shelf life and COA

The barcode details batch number and expiry date of reagents, which are documented along with the measurement result. An automatic warning is issued if expiry date has passed. Certificate of Analysis (COA) is available on the RFID tag on the box, which can be read out with the DR3900 or DR6000 spectrophotometer.

No reagent blank necessary

The high quality of TNTplus vials, tight reagent production controls, instrument calibration verification, and high instrument stability all combine to eliminate the need to run reagent blanks —saving you time and money!

Safe and easy handling

TNTplus vials use innovative Dosicaps that are easier to use than powder pillows or liquid reagents. There’s no risk of spillage, no safety risk, or risk of contamination with Dosicaps because the reagents are completely contained within the vial cap. The glassware used assures the best precision and the vials have a flat bottom so they can stand on their own. Packages of TNTplus vials are color-coded for fast and easy parameter and range recognition for the exact test you need. Step-by-step illustrated test methods are printed on the box for quick reference.
