Product Overview
The Platinum Cobalt Color Standard 25 (HAZ 25) is a high-precision Pt-Co (Hazen) color standard solution designed for accurate colorimetric measurements in laboratory settings. This ISO-compliant reagent provides a stable and consistent reference for color analysis, ensuring reliable results in water quality testing, chemical research, and industrial applications. The solution is formulated with platinum and cobalt salts to produce a standardized color intensity corresponding to Hazen 25, making it an essential tool for maintaining quality control and calibration in color-sensitive experiments. Its long shelf life and resistance to degradation ensure repeatable performance, while the laboratory reagent grade guarantees purity and minimal interference in analytical procedures. Whether used in routine testing or specialized research, this color standard delivers the precision required for professional-grade color assessment.
FAQs
1. What is the shelf life of the Platinum Cobalt Color Standard 25?
The solution remains stable for 24 months when stored in its original sealed container at room temperature, away from direct sunlight.
2. Is this color standard compatible with automated colorimeters?
Yes, it is fully compatible with most laboratory-grade colorimeters and spectrophotometers calibrated for Pt-Co/Hazen measurements.
3. Are there alternative color standards for higher or lower Hazen values?
Alternative Pt-Co standards are available across the Hazen scale, including lower (e.g., 5, 10) and higher (e.g., 50, 100) values for broader applications.
4. How should this solution be stored to maintain accuracy?
Store upright in a cool, dark place with the cap tightly sealed to prevent evaporation or contamination.
5. Can this standard be used for field testing?
While designed for lab use, it can be used in field kits if protected from temperature fluctuations and physical agitation.
