Product Overview
The density standard (0.9476 g/ml at 20°C) is a high-precision reference material designed for laboratory calibration applications. Manufactured under stringent quality controls, this certified reference material (CRM) ensures traceability to international standards, providing reliable and reproducible results. The liquid form is chemically stable, minimizing evaporation or degradation over time, which is critical for long-term accuracy in density measurements. Each batch undergoes rigorous testing to confirm its stated density value, with certification documentation included for compliance and audit purposes. The standard is compatible with most densitometers, pycnometers, and hydrometers, making it versatile for various analytical workflows. Its low thermal expansion coefficient reduces temperature-induced errors, while the sealed packaging prevents contamination or moisture absorption. Ideal for laboratories requiring NIST-traceable or ISO-compliant reference materials, this density standard eliminates variability in instrument calibration, ensuring consistency across experiments. The non-hazardous composition simplifies handling and disposal, adhering to standard lab safety protocols. Whether used in routine quality control or research-grade applications, this density standard delivers the precision demanded by modern analytical laboratories.
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 room temperature (15–25°C). Avoid exposure to direct sunlight or extreme temperatures to maintain accuracy.
2. Can this standard be used with digital densitometers?
Yes, this density standard is fully compatible with digital densitometers, including oscillating U-tube and vibrating element types. Its certified value ensures accurate calibration across most modern instruments without requiring additional adjustments.
3. Is this standard traceable to NIST or other international bodies?
The density standard is traceable to primary reference materials aligned with NIST (National Institute of Standards and Technology) and ISO Guide 34/35. Certification documentation provided with each unit includes traceability details for compliance and auditing.
4. How should I store the density standard after opening?
After opening, reseal the container tightly and store it upright in a cool, dry place (15–25°C). Minimize air exposure to prevent evaporation or contamination. For long-term storage, consider transferring smaller aliquots to airtight secondary containers.
5. Are there alternatives for higher or lower density ranges?
Alternatives are available for densities ranging from 0.690 g/ml to 1.900 g/ml, including common reference points like 0.789 g/ml (ethanol), 1.000 g/ml (water), and 1.750 g/ml. Contact support for specific requirements or custom density standards.
