Product Overview
This high-precision density standard (0.7184 g/ml at 15°C) is a certified reference material designed for laboratory calibration applications. Manufactured under stringent quality controls, it offers a tolerance of ±0.0002 g/ml, ensuring reliable and reproducible results for critical density measurements. The solution is prepared using ultra-pure solvents and stabilized to maintain long-term accuracy, making it suitable for calibrating hydrometers, pycnometers, and electronic densitometers. Each batch undergoes rigorous testing against NIST-traceable standards, with certification documentation provided for quality assurance. The 100 ml pack size provides sufficient volume for multiple calibrations while minimizing waste. The liquid form allows for easy handling and precise dispensing in laboratory environments. This density standard is particularly valuable in industries requiring strict adherence to measurement protocols, where even minor deviations can impact experimental outcomes. The temperature-specific certification at 15°C ensures compatibility with standard laboratory conditions, eliminating the need for complex temperature corrections during calibration procedures.
FAQs
1. What is the shelf life of this density standard?
The density standard remains stable for 24 months from the date of manufacture when stored unopened in its original container at room temperature. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used for calibrating digital densitometers?
Yes, this density standard is compatible with both analog and digital densitometers. Its NIST-traceable certification ensures reliable calibration across different instrument types.
3. How should I store this density standard to maintain its accuracy?
Store the unopened bottle upright at 15-25°C, away from direct sunlight and moisture. After opening, keep the container tightly sealed when not in use to prevent evaporation or contamination.
4. Is this density standard suitable for field calibration?
While primarily designed for laboratory use, this standard can be used for field calibration if proper temperature control (15°C) and handling procedures are maintained during measurements.
5. What documentation is provided with this density standard?
Each bottle comes with a certificate of analysis including the certified density value, measurement uncertainty, traceability information, and batch-specific data for quality assurance.
