Reduce Errors with Bar-coded Vials and RFID
A unique barcode label on each Hach TNTplus Vial Chemistry is automatically read by the spectrophotometer when used with Hach’s DR 6000™ UV-VIS Spectrophotometer or DR 3900™ Benchtop Spectrophotometer to identify the appropriate method and take the measurement. While increasing ease-of-use and speed of analysis, errors are significantly reduced. In addition, the user will receive a notification if shelf life of a TNTplus test has been expired. The RFID tag on each TNTplus box contains the lot specific Certificate of Analysis which can be read out with the DR 6000™ or DR 3900™ spectrophotometer.
No Reagent Blank Necessary
The high quality of TNTplus vials, tight reagent production controls, 10-fold absorbance readings averaged for results determination, instrument calibration verification, and high instrument stability all combine to eliminate the need to run reagent blanks—saving you time and money!
Innovative Vial and Reagent Delivery
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.
Helpful package design
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.
