With proprietary manufacturing technology, Hach prepares Stablcal Standards in precise concentrations at a wide variety of concentrations - providing accurate turbidimeter calibrations.
Based on Formazin Primary Standards
Stablcal Stabilized Formazin Standards contain the same light scattering polymer as traditional Formazin primary turbidity standards - and perform equivalently.
Enhanced Stability Saves Time and Labor
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 stabilised version of Formazin - providing repeatable results, without the time and effort required for lab-prepared standards.
Confidence in results
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.
