Product Overview
This refractive index standard is a stabilized sucrose solution designed for precise calibration of refractometers at 20°C, delivering a consistent refractive index of 1.34325. The formulation ensures long-term stability, minimizing evaporation or degradation over time. The solution is filtered to remove particulates, guaranteeing optical clarity for accurate readings. Packaged in a sealed amber bottle, it protects against light-induced degradation, preserving integrity during storage. The laboratory-grade purity meets stringent quality controls, making it suitable for research and analytical applications requiring high repeatability. Each batch undergoes rigorous testing to confirm compliance with specified refractive index values, ensuring reliable performance in critical measurements. The compact 15 ml pack size provides sufficient volume for multiple calibrations while reducing waste. Compatible with most digital and analog refractometers, this standard simplifies calibration procedures, improving workflow efficiency in laboratory settings.
FAQs
1. What is the shelf life of this refractive index standard?
When stored unopened in its original packaging at room temperature, the solution remains stable for 24 months from the date of manufacture.
2. Can this standard be used with handheld refractometers?
Yes, it is compatible with both handheld and benchtop refractometers, provided they operate within the 1.33-1.35 refractive index range.
3. How should I store the solution after opening?
Recap the bottle tightly and store it in a cool, dark place. Avoid prolonged exposure to direct sunlight or temperature fluctuations.
4. Is this solution traceable to national standards?
The refractive index value is verified against certified reference materials, though it is not accompanied by a formal traceability certificate.
5. What alternatives exist for different refractive index ranges?
For higher or lower ranges, consider glycerin-based standards (1.4-1.5) or sodium chloride solutions (1.33-1.34) depending on your calibration needs.
