Product Overview
This refractive index standard (1.35093 at 20°C) is a stabilized sucrose solution designed for precise calibration of refractometers and optical instruments. Formulated to maintain consistency over time, it ensures reliable and repeatable measurements in laboratory settings. The solution is filtered and degassed to eliminate impurities, providing a clear and stable reference for refractive index testing. Its analytical-grade purity makes it suitable for demanding applications where accuracy is critical. The liquid form allows for easy handling and application, while the 15 ml pack size offers convenience for frequent use. Whether used in research, quality assurance, or routine testing, this standard delivers consistent performance, reducing variability in optical measurements. The temperature-specific calibration (20°C) ensures compatibility with standard laboratory conditions, making it a versatile choice for various testing protocols.
FAQs
1. What is the shelf life of this refractive index standard?
The stabilized sucrose solution remains accurate for up to 24 months when stored unopened in a cool, dry place. Once opened, use within 6 months for optimal performance.
2. Can this standard be used with digital and analog refractometers?
Yes, it is compatible with both digital and analog refractometers, provided they are calibrated for the 1.35093 refractive index at 20°C.
3. Are there alternatives for different refractive index values?
Alternative standards are available for varying refractive indices, such as 1.3330 or 1.4700, depending on specific calibration requirements.
4. 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.
5. Is this solution suitable for field testing applications?
While primarily designed for laboratory use, it can be used in field testing if stored and handled under controlled conditions to avoid contamination.
