Product Overview
This refractive index standard (1.44193 at 20°C) is a stabilized sucrose solution designed for precise calibration of refractometers and optical instruments. The formulation ensures long-term stability, minimizing evaporation or composition changes that could affect accuracy. With a certified refractive index value, it provides a reliable reference point for routine laboratory measurements. The solution is prepared under controlled conditions to meet analytical-grade purity standards, ensuring consistency across batches. Its low viscosity allows for easy handling and quick stabilization during measurements. The 15 ml pack size offers sufficient volume for multiple calibrations while maintaining freshness. This standard is particularly useful in quality control processes where optical property verification is critical. The stabilized formulation reduces the need for frequent recalibration, saving time and improving workflow efficiency. Compatible with most commercial refractometers, it serves as a cost-effective alternative to more expensive certified reference materials while maintaining comparable accuracy.
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, it is compatible with both digital and analog refractometers, providing accurate calibration for instruments measuring in the 1.441-1.443 refractive index range.
3. How does temperature affect the measurement accuracy?
The standard is certified at 20°C. For precise results, ensure both the standard and refractometer are temperature-equilibrated to 20°C before measurement.
4. What alternatives exist for different refractive index ranges?
For other ranges, consider standards like 1.3330 (water), 1.4760 (glycerol), or 1.5150 (bromonaphthalene) depending on your specific calibration needs.
5. How should I store this standard to maintain its accuracy?
Store upright in a cool, dry place away from direct sunlight. Always reseal the container immediately after use to prevent contamination or evaporation.
