Product Overview
The platinum cobalt color 50 (HAZ 50) standard is a high-precision reference solution designed for accurate color measurement in liquids. Formulated with platinum and cobalt chlorides, this solution provides a stable 50 Hazen (Pt-Co) color intensity, making it ideal for colorimetric applications where consistency and reliability are critical. The standard adheres to international norms, ensuring compatibility with ISO 6271 and ASTM D1209 methodologies for water and chemical analysis. Its analytical-grade purity guarantees minimal interference, while the sealed packaging prevents contamination and degradation over time. The solution’s long-term stability eliminates the need for frequent recalibration, reducing operational costs in laboratory settings. Whether used in quality control, research, or routine testing, this color standard delivers repeatable results, supporting compliance with regulatory requirements. The 1000 ml pack size offers an optimal balance between volume and shelf life, minimizing waste while ensuring availability for high-frequency testing environments.
FAQs
1. What is the shelf life of the platinum cobalt color 50 standard?
The solution remains stable for 24 months when stored in its original, tightly sealed container at room temperature, away from direct sunlight and moisture. Always check the label for the exact expiration date.
2. Can this standard be used for measuring color in non-aqueous solvents?
The Pt-Co Hazen 50 standard is primarily calibrated for aqueous solutions. For non-aqueous solvents, compatibility should be verified through preliminary testing, as solvent polarity may affect color perception and accuracy.
3. How does this compare to the APHA color scale?
The Hazen (Pt-Co) scale and APHA scale are identical in numerical values; a Hazen 50 standard corresponds to an APHA 50 standard. Both are used interchangeably in colorimetric analysis for liquids like water, oils, and chemicals.
4. What precautions should be taken during handling?
While non-toxic, the solution should be handled with standard lab precautions: wear gloves and safety goggles to avoid skin or eye contact. Clean spills immediately with water to prevent staining.
5. Is recalibration required after opening the bottle?
No recalibration is needed if the bottle is resealed properly after each use. However, exposure to air over extended periods may lead to slight evaporation or contamination, so it’s advisable to use the solution within 6 months of opening for optimal accuracy.
