Product Number: 2660542
Ready to use, stabilised Formazine Primary standard solution in 100 mL bottle, 800 NTU.
USEPA accepted for calibration purposes. Stablcal Stabilised Formazin Turbidity Standards are true Formazin dilutions developed for use in any turbidimeter. For TL23, TU52, 2100Q, 2100N, 2100AN series.
With proprietary manufacturing technology, Hach prepares Stablcal Standards in precise concentrations at a wide variety of concentrations - providing accurate turbidimeter calibrations.
Stablcal Stabilized Formazin Standards contain the same light scattering polymer as traditional Formazin primary turbidity standards - and perform equivalently.
While Formazin primary standards can be prepared directly in the lab, the process is labor intensive and time consuming - and the diluted standards are not stable. Stablcal is a stabilized version of Formazin - providing repeatable results, without the time and effort required for lab-prepared standards.
Hach was the first to apply Formazin as a turbidity standard in the drinking water industry, more than 40 years ago. Stablcal standards are based on decades of experience in turbidity measurement.
