Product Overview

The refractive index standard (1.50044 at 20°C) is a solvent-based liquid designed for precise calibration of refractometers and optical instruments. Formulated with high-purity materials, this standard ensures accurate and repeatable measurements in laboratory settings. Its stable composition minimizes evaporation and degradation, maintaining long-term reliability. The refractive index value is certified at 20°C, providing a consistent reference point for optical testing. This standard is ideal for applications requiring strict adherence to measurement protocols, offering low variability and high reproducibility. The liquid form allows for easy handling and application, reducing the risk of contamination or spillage. Compatible with most refractometers, it eliminates the need for frequent recalibration, saving time and resources. The solvent-based formulation ensures compatibility with a wide range of optical systems, making it a versatile choice for labs requiring precise refractive index control.

FAQs

1. What is the shelf life of this refractive index standard?

The shelf life is typically 24 months from the date of manufacture when stored in a tightly sealed container at room temperature, away from direct sunlight.

2. Can this standard be used with digital refractometers?

Yes, it is compatible with both analog and digital refractometers, provided the instrument is designed for liquid standards.

3. Are there alternatives for different refractive index values?

Yes, alternative standards are available for other refractive index values, such as 1.4750 or 1.5150, depending on specific calibration needs.

4. How should this standard be stored to maintain accuracy?

Store the bottle upright in a cool, dry place, preferably between 15°C and 25°C, and ensure the cap is tightly closed after each use to prevent evaporation.

5. Is this standard traceable to national or international standards?

The refractive index value is certified and traceable to NIST (National Institute of Standards and Technology) or equivalent international standards for accuracy.
