Product Overview
This solvent-based refractive index standard is meticulously formulated to provide a reference value at 20°C, ensuring precise calibration of refractometers and other optical instruments. The standard’s composition is optimized for stability, resisting evaporation and chemical degradation to maintain accuracy over extended use. Its analytical grade purity eliminates impurities that could skew measurements, making it a trusted choice for laboratories requiring repeatable results. The liquid form allows for easy application, while the sealed packaging prevents contamination and preserves the standard’s integrity. Designed for both routine and high-stakes calibration, this product minimizes instrumental drift and enhances the reliability of refractive index determinations. The 15 ml volume balances practicality and efficiency, reducing waste while accommodating frequent recalibration needs. Whether for educational labs, research facilities, or industrial quality control, this standard delivers consistent performance, aligning with international metrological standards for traceability and precision.
FAQs
1. Does this standard require temperature equilibration before use?
Yes, allow the standard to reach 20°C (±0.1°C) before calibration to ensure accurate readings, as temperature fluctuations affect refractive index values.
2. Can it be reused multiple times, or is it single-use?
The standard can be reused if stored properly and uncontaminated, but replace it if cloudiness or particulate matter is observed.
3. What solvents are used in this standard’s formulation?
The base solvent is typically a high-purity hydrocarbon or alcohol blend, selected for optical clarity and stability at the specified temperature.
4. How does humidity affect the standard’s performance?
High humidity can cause moisture absorption, altering the refractive index; always seal the bottle tightly after use and store in dry conditions.
5. Is recertification available if the standard expires?
Recertification is not offered, but fresh batches with updated certification are available for purchase to maintain compliance.
