Product Overview
This density standard (0.6960 g/ml at 15°C) is a high-precision reference material designed for calibrating laboratory instruments requiring exact density measurements. Formulated with ultra-pure components, it ensures long-term stability and traceability to NIST standards, eliminating batch-to-batch variability. The liquid form allows for easy handling and dispensing, while its certified CRM grade guarantees compliance with ISO and GLP requirements. Each batch undergoes rigorous testing for homogeneity and accuracy, with a certificate of analysis provided for quality assurance. The standard’s low thermal expansion coefficient minimizes temperature-induced errors, making it ideal for environments where precise density control is critical. Compatible with glass, stainless steel, and PTFE, it resists contamination and degradation over extended use. Whether for routine calibration or validation protocols, this density standard delivers consistent, reproducible results without the need for frequent recalibration.
FAQs
1. What is the shelf life of this density standard?
When stored unopened in its original container at 15–25°C, the standard remains stable for 24 months from the date of manufacture. Avoid exposure to direct sunlight or temperature fluctuations.
2. Can this standard be used with automated densitometers?
Yes, it is fully compatible with automated and manual densitometers, including Anton Paar, Mettler Toledo, and Rudolph models. Ensure the instrument is cleaned with isopropanol before use to prevent cross-contamination.
3. Are there alternatives for higher or lower density ranges?
For broader calibration needs, consider our density standards at 0.799 g/ml (ethanol-based) or 1.000 g/ml (water-based). These cover common lab requirements while maintaining the same CRM-grade precision.
4. How should I dispose of expired or unused standard?
Dispose of as non-hazardous chemical waste according to local regulations. Neutralize with water if required, but avoid mixing with other solvents to prevent reactions.
5. Is this standard traceable to international metrology institutes?
Yes, it is traceable to NIST (National Institute of Standards and Technology) via an unbroken chain of comparisons, with certification documentation included in each shipment.
