Product Overview
The density standard (1.1639 g/ml at 25°C) is a certified reference material designed for precise calibration of laboratory instruments. Formulated with ultra-pure components, this standard ensures long-term stability and accuracy, meeting stringent ISO and NIST traceability requirements. Its low thermal expansion coefficient minimizes temperature-induced errors, making it ideal for critical measurements in research and industrial settings. The liquid form allows easy handling and dispensing, while the tamper-evident packaging guarantees integrity upon delivery. Compatible with most densitometers, pycnometers, and hydrometers, this standard eliminates measurement uncertainties caused by instrument drift. Each batch undergoes rigorous multi-point verification to confirm its stated density value, with a certificate of analysis provided for quality assurance. The non-volatile composition prevents evaporation losses during storage, maintaining its calibration properties over extended periods. Whether used for routine quality control or high-precision research, this density standard delivers consistent, reproducible results that comply with international metrology standards.
FAQs
1. What is the shelf life of this density standard?
When stored unopened in its original container at 15-25°C, this density standard maintains its certified value for at least 24 months from the date of manufacture. Always check the expiration date on the certificate of analysis.
2. Can this standard be used with automatic densitometers?
Yes, this density standard is fully compatible with both manual and automatic densitometers. Its low viscosity and non-corrosive properties ensure smooth operation without damaging instrument components.
3. How should I handle temperature variations during calibration?
The certified value is specified at 25°C. For accurate results, allow the standard to equilibrate to your lab’s ambient temperature before use. Most modern instruments have built-in temperature compensation features.
4. What documentation comes with this density standard?
Each unit includes a certificate of analysis with traceability information, measured density values at multiple temperatures, uncertainty statements, and storage instructions for compliance documentation.
5. Are there any special disposal requirements for this standard?
While this standard contains no hazardous components, follow your institution’s chemical waste disposal protocols. The non-toxic formulation allows for standard laboratory waste disposal in most jurisdictions.
