Description

Stablcal Formazin Turbidity Standard, 0.50 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 concentration does the Stablcal verification standard contain?

Answer:It is a stabilized formazin turbidity standard rated at 0.50 NTU.

Question: How much solution is supplied?

Answer:The standard comes in a 100 mL bottle.

Question: Can the 0.50 NTU standard replace the TL2360 calibration set?

Answer:No. The TL2360 manual designates the 0.50 NTU solution for low-level verification, not calibration.

Application Note

Hach Stablcal 0.50 NTU turbidity standard provides a prepared, stabilized formazin suspension for checking the response of turbidimeters at very low turbidity. The 100 mL presentation fits routine water-quality monitoring in laboratories working with municipal water, groundwater, or surface water. The standard serves as a defined 0.50 NTU reference point in verification and quality-control procedures with compatible Hach TL23, TU52, 2100Q, 2100N, and 2100AN instruments. The TL2360 manual specifically lists this concentration for low-level verification rather than instrument calibration. Careful sample-cell cleaning and prevention of trapped bubbles are especially important when reading low-turbidity standards.
