Product Overview
This solvent-based refractive index standard is engineered to provide a consistent benchmark for calibrating refractometers and optical instruments at 20°C. Its analytical-grade purity ensures minimal variability, making it ideal for laboratories where precision is critical. The liquid form allows for easy application and cleaning, reducing the risk of residue buildup on instrument surfaces. Packaged in a 15 ml bottle, it offers a practical volume for frequent calibrations without excessive waste. The standard’s formulation resists evaporation and degradation, maintaining its certified properties over extended storage periods when handled correctly. Its compatibility with a wide range of refractometer models—both portable and benchtop—makes it a versatile choice for diverse lab environments. The absence of reactive components ensures it does not interact with common lab materials, preserving the integrity of both the standard and the equipment. Whether used for routine maintenance or critical validation, this refractive index standard delivers reliable performance, supporting accurate optical measurements in research, quality control, and industrial applications.
FAQs
1. Does this standard require any special handling during use?
While no special handling is required, it is recommended to use a clean dropper or pipette to avoid contamination. Wipe the refractometer prism with a lint-free cloth after application.
2. Can this standard be used for calibrating Abbe refractometers?
Yes, it is suitable for Abbe refractometers and other high-precision optical instruments, provided the temperature is stabilized at 20°C during calibration.
3. What is the typical uncertainty range for this standard?
The standard has an uncertainty of ±0.0002, ensuring high confidence in calibration results for most laboratory and industrial applications.
4. Is recalibration of the standard required over time?
No recalibration is needed if stored properly. However, verify the standard’s performance periodically by comparing it with a fresh, unopened bottle if accuracy is suspect.
5. Are there any safety precautions for disposal?
Dispose of the standard according to local regulations for solvent-based laboratory chemicals. Avoid pouring it down drains; use approved chemical waste containers instead.
