Product Overview
This density standard (1.8994 g/ml at 40°C) is a certified reference material designed for high-precision calibration of densitometers, pycnometers, and other density-measuring instruments. Manufactured under strict quality control, it offers a certified accuracy of ±0.0002 g/ml, ensuring reliable and reproducible results in laboratory settings. The fluid is formulated with ultra-pure components to minimize evaporation and contamination risks, maintaining stability over extended periods. Each batch undergoes rigorous testing against NIST-traceable standards, with a certificate of analysis provided for documentation. The low thermal expansion coefficient ensures consistent performance across temperature variations, while the non-corrosive composition protects laboratory equipment. Packaged in amber glass bottles with PTFE-lined caps, it prevents moisture ingress and light-induced degradation. Ideal for quality assurance protocols, this standard meets ISO 9001 and GLP compliance requirements, making it suitable for regulated industries and research applications requiring traceable measurements.
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 original packaging at 15-25°C. After opening, use within 6 months for optimal accuracy.
2. Can this standard be used with digital densitometers?
Yes, it is fully compatible with all digital densitometers including Anton Paar, Mettler Toledo, and Rudolph models. The viscosity is optimized for quick stabilization in measurement cells.
3. How does temperature affect the certified density value?
The certified value of 1.8994 g/ml is specific to 40°C. Temperature variations will alter the density; use the provided temperature correction table or instrument software for adjustments.
4. What alternatives are available for lower density calibration?
For lower density ranges, consider our 0.7993 g/ml (ethanol-based) or 1.0000 g/ml (water-based) standards, both available with similar NIST-traceable certification.
5. Is this standard suitable for pharmaceutical quality control?
Yes, it meets USP requirements for density determination in pharmaceuticals. The certificate of analysis includes batch-specific data for regulatory documentation.
