Product Overview
The Platinum Cobalt Color Standard (Pt-Co/Hazen 100) is a meticulously formulated liquid reference solution designed for accurate colorimetric measurements in laboratory and industrial settings. This standard adheres to the internationally recognized Pt-Co/Hazen scale, ensuring consistency and reproducibility in color assessments. The solution is prepared using high-purity platinum and cobalt salts dissolved in a stable, non-reactive solvent, providing a uniform color intensity that remains stable over extended periods when stored correctly. Its precise 100-unit concentration makes it ideal for calibrating spectrophotometers, validating visual color comparison methods, or establishing baseline measurements in quality control protocols. The product is manufactured under stringent conditions to meet ISO and ASTM standards, guaranteeing minimal batch-to-batch variation. Its chemical stability reduces the risk of degradation from light exposure or temperature fluctuations, while the sealed packaging prevents contamination. Whether used for routine lab testing or critical research applications, this color standard delivers reliable performance, eliminating subjective errors in color evaluation. The solution’s compatibility with standard glassware and automated dispensing systems further enhances its practical utility in modern laboratories.
FAQs
1. What is the shelf life of this Pt-Co/Hazen 100 color standard?
The solution remains stable for 24 months from the date of manufacture when stored unopened in its original packaging at room temperature, away from direct sunlight. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used with automated colorimeters?
Yes, the Pt-Co/Hazen 100 standard is fully compatible with most automated colorimeters and spectrophotometers, provided the instrument is calibrated to the Pt-Co/Hazen scale. Always verify the device’s measurement range before use.
3. Are there lower or higher concentration alternatives available?
This product is specifically formulated at 100 units, but the Pt-Co/Hazen scale includes standards ranging from 5 to 500 units. For other concentrations, separate standards must be sourced as this solution cannot be diluted or concentrated without compromising accuracy.
4. How should this standard be stored to maintain accuracy?
Store the unopened bottle upright in a cool, dark place (15–25°C). After opening, keep the container tightly sealed and avoid exposure to moisture or airborne contaminants. Do not refrigerate, as temperature fluctuations may cause condensation.
5. Does this standard require any special disposal procedures?
While the solution is non-hazardous under normal conditions, dispose of it in accordance with local laboratory waste regulations. Small quantities can typically be neutralized and flushed with excess water, but confirm with your institution’s safety protocols for liquid chemical waste.
