Product Overview
This refractive index standard (1.35015 at 20°C) is a stabilized sucrose solution designed for precise refractometry calibration. Engineered to deliver consistent optical measurements, it ensures accurate instrument performance in laboratory settings. The solution is formulated to maintain stability over time, minimizing evaporation or compositional changes that could affect readings. Its lab-grade purity eliminates contaminants that may interfere with refractive index accuracy, making it a reliable reference for routine calibrations. The 15 ml pack size provides sufficient volume for multiple uses while maintaining freshness. Compatible with most refractometers, this standard adheres to international measurement protocols, offering traceability to certified reference materials. Its ready-to-use formulation eliminates the need for preparation, saving time in busy lab environments. The solution’s optical properties are verified under controlled conditions to guarantee reproducibility across different instruments and operators.
FAQs
1. What is the shelf life of this refractive index standard?
The stabilized sucrose formulation maintains accuracy for up to 24 months when stored properly in its original sealed container at room temperature.
2. Can this standard be used with digital and analog refractometers?
Yes, the solution is compatible with both digital and analog refractometers, as it meets the optical property requirements for standard calibration procedures.
3. How should I store this refractive index standard?
Store the unopened bottle at 15-25°C, away from direct sunlight and moisture. Keep the cap tightly sealed when not in use to prevent evaporation.
4. Is this standard traceable to NIST or other certification bodies?
The refractive index value is verified against certified reference materials, though direct NIST traceability would require additional documentation from the manufacturer.
5. What alternatives exist for different refractive index ranges?
For other calibration points, consider standards with values like 1.3330 (water reference) or 1.4760 (high-range), depending on your measurement requirements.
