Product Overview
The Platinum Cobalt Color 80 (HAZ 80) standard is a pre-calibrated solution designed for accurate colorimetric measurements in laboratory settings. This Pt-Co/Hazen standard adheres to international color scales, ensuring reproducibility in water quality assessments, chemical purity tests, and industrial process monitoring. The solution is stabilized to prevent degradation, maintaining its 80 Hazen color value over extended storage periods when handled under recommended conditions. Its analytical-grade formulation eliminates variability, making it ideal for comparative analysis against samples with similar color intensities. The 1000 ml packaging provides sufficient volume for repeated testing while minimizing contamination risks through its sealed, light-resistant container. Compatible with most spectrophotometric and visual comparison methods, this standard serves as a reliable reference for both routine lab work and specialized research applications where precise color quantification is critical.
FAQs
1. What is the shelf life of this Pt-Co/Hazen 80 color standard?
The solution remains stable for 24 months from the date of manufacture when stored unopened in its original container at room temperature, away from direct sunlight. Always check the expiration date on the label before use.
2. Can this standard be diluted to create lower Hazen values?
Yes, the solution can be diluted with deionized water to prepare standards of lower color intensities, but recalibration is recommended after dilution to ensure accuracy, as minor deviations may occur.
3. Is this compatible with automated colorimeters?
The standard is designed for compatibility with most automated spectrophotometric systems, but verify the wavelength settings (typically 455 nm for Hazen measurements) and cuvette specifications of your specific instrument.
4. How should I dispose of expired or unused solution?
Follow local laboratory waste disposal regulations. As a non-hazardous chemical waste, it can typically be neutralized and disposed of via approved chemical waste streams, but consult your institution’s safety protocols.
5. What alternatives exist for measuring higher color intensities?
For values above 80 Hazen, consider Pt-Co standards with higher concentrations (e.g., HAZ 100 or HAZ 500) or alternative color scales like Gardner or Saybolt, depending on your specific application requirements.
