Description

Stablcal Formazin Turbidity Standard, 0.30 NTU. 100 mL Bottle. For TL23, TU52, 2100Q, 2100N, 2100AN series.
Precise, Pre-mixed Formazin Solutions
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 stabilized 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.

FAQs

Question: What is the turbidity value of this Stablcal standard?

Answer:The stabilized formazin standard has a nominal turbidity of 0.30 NTU.

Question: Is the 0.30 NTU standard used for TL2360 calibration?

Answer:No. The TL2360 instrument manual identifies it as a low-level verification standard, not a calibration standard.

Question: Which Hach turbidimeter families use the Stablcal standard?

Answer:Compatible families include TL23, TU52, 2100Q, 2100N and 2100AN.

Application Note

Hach Stablcal 0.30 NTU turbidity standard is a ready-to-use, stabilized formazin suspension for low-level turbidity verification in water analysis. Its 0.30 NTU value supports checks of instrument response near the lower end of the measuring range, particularly when testing drinking water, groundwater, and surface water. The 100 mL bottle supplies prepared material without laboratory dilution of a concentrated formazin stock. Compatible instrument families include Hach TL23, TU52, 2100Q, 2100N, and 2100AN. In TL2360 workflows, this low-level standard is used for verification rather than the instrument's calibration procedure. Appropriate mixing and clean measurement cells help protect low-turbidity measurements from handling artifacts.
