FAQs
1. What is the shelf life of this refractive index standard?
The stabilized sucrose solution maintains its accuracy for up to 24 months when stored properly in its original sealed container.
2. Can this standard be used with digital refractometers?
Yes, it is fully compatible with both digital and analog refractometers that require calibration at 1.38115 RI.
3. How should this standard be stored to maintain accuracy?
Store the bottle tightly sealed at room temperature (15-25°C), away from direct sunlight and moisture to prevent degradation.
4. Is this standard traceable to international measurement standards?
The refractive index value is verified against NIST-traceable references to ensure measurement reliability.
5. What alternatives exist for different refractive index ranges?
For other calibration needs, consider standards with RI values like 1.3330 (water) or 1.5150 (glass) depending on your instrument range.
