Product details
Hach StablCal Stabilized Formazin Turbidity Standards
StablCal standards are ready-made formazin turbidity standards that stay stable, unlike formazin diluted in the laboratory, which must be made fresh and takes time. They contain the same light-scattering polymer as primary formazin and are accepted by the USEPA for turbidimeter calibration.
