Product Overview
This density standard (0.7488 g/ml at 20°C) is a high-precision reference fluid designed for laboratory calibration applications where accuracy is critical. Formulated with ultra-pure components, it offers exceptional stability and minimal thermal expansion, ensuring consistent measurements across temperature variations. The standard is NIST-traceable, providing documented certification that meets ISO 9001 and GLP requirements for quality assurance. Its low viscosity and non-corrosive properties make it compatible with most glass and metal laboratory equipment. The fluid is pre-filtered to 0.2 µm to eliminate particulate contamination, while its sealed packaging prevents moisture absorption and evaporation. Each batch undergoes rigorous testing for density accuracy (±0.0002 g/ml) and long-term stability, with a shelf life of 24 months when stored under recommended conditions. The transparent formulation allows for visual inspection of purity, and its non-hazardous composition simplifies handling and disposal procedures.
FAQs
1. What is the temperature coefficient for this density standard?
The temperature coefficient is approximately 0.00085 g/ml/°C, allowing for precise corrections when used outside the 20°C reference temperature.
2. Can this standard be used with automatic densitometers?
Yes, it is fully compatible with both manual and automatic densitometers, including oscillating U-tube and digital vibrating element instruments.
3. What alternatives exist for higher density calibration?
For higher density ranges, consider our 0.8235 g/ml or 1.0000 g/ml standards, which maintain the same precision specifications and certification levels.
4. How should this standard be stored for long-term use?
Store upright in its original container at 15-25°C, away from direct sunlight and heat sources. Keep the bottle tightly sealed to prevent evaporation.
5. Is this standard suitable for pharmaceutical quality control?
While primarily designed for physical property testing, its NIST traceability and high purity make it acceptable for non-GMP pharmaceutical applications where density verification is required.
