Product Overview
This density standard (0.9857 g/ml at 40°C) is a high-precision reference material designed for laboratories requiring exact density measurements. Manufactured under stringent quality controls, it ensures traceability to NIST standards, guaranteeing reliability in calibration procedures. The solution is formulated with ultra-pure components to minimize evaporation and maintain long-term stability, reducing the need for frequent recalibrations. Its low thermal expansion coefficient ensures consistent performance across temperature variations, making it suitable for environments where temperature fluctuations are common. The standard is supplied in a tamper-evident, amber glass bottle to prevent photodegradation and contamination, preserving its integrity during storage and handling. Each batch undergoes rigorous testing for homogeneity and stability, with certification documentation provided for compliance with ISO 9001 and GLP standards. The non-hazardous composition simplifies disposal while adhering to lab safety protocols. Whether used in routine quality checks or critical research applications, this density standard delivers unmatched accuracy, reducing measurement uncertainties and enhancing reproducibility in experimental workflows.
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 packaging at 15–25°C. Avoid exposure to direct sunlight or temperature extremes to prevent degradation.
2. Can this standard be used for calibrating digital densitometers?
Yes, the 0.9857 g/ml value is compatible with most digital densitometers, including Anton Paar and Mettler Toledo models. Ensure the instrument’s temperature compensation is set to 40°C for accurate readings.
3. Are there alternatives for lower temperature calibrations?
For calibrations below 40°C, consider density standards with values certified at 20°C or 25°C. These are available in similar CRM grades and pack sizes for consistent methodology.
4. How should I handle spills or disposal?
Wipe spills with an absorbent cloth and rinse the area with water. Dispose of the standard as non-hazardous chemical waste according to local regulations, though it contains no toxic components.
5. Is recertification available after opening the bottle?
Recertification is not provided post-opening, as exposure to air may alter the density. Use the standard within 6 months of opening and store it tightly sealed to minimize evaporation.
