Product Overview
This density standard (0.7298 g/ml at 15°C) is a certified reference material designed for high-precision calibration of laboratory instruments. Formulated with ultra-pure components, it ensures NIST-traceable accuracy, making it indispensable for quality control and analytical testing. The solution is stable under standard lab conditions, minimizing evaporation and compositional changes over time. Its low thermal expansion coefficient guarantees consistent performance across temperature variations, while the sealed packaging prevents contamination. The density value is verified through gravimetric methods, providing reliability for critical measurements. Compatible with most glass and plastic labware, this standard eliminates measurement uncertainties, ensuring compliance with ISO and ASTM standards. The 100 ml pack size offers sufficient volume for repeated calibrations without frequent replacements. Each batch undergoes rigorous testing to confirm homogeneity and long-term stability, making it a trusted choice for laboratories requiring traceable, high-accuracy density references.
FAQs
1. What is the shelf life of this density standard?
When stored in its original sealed container at room temperature, this density standard maintains its certified accuracy for at least 24 months from the date of manufacture. Avoid exposure to direct sunlight or extreme temperatures to preserve its properties.
2. Can this standard be used with automatic density meters?
Yes, this density standard is fully compatible with most automatic density meters, including those from Anton Paar and Mettler Toledo. Its formulation ensures consistent readings across different instrument types without requiring recalibration adjustments.
3. How should I handle spills or accidental exposure?
While non-toxic, this solution should be handled with standard lab precautions. In case of skin contact, rinse thoroughly with water. For spills, absorb with inert material like sand or vermiculite and dispose of according to local chemical waste regulations.
4. Is this standard affected by temperature fluctuations during shipping?
The solution is packaged in temperature-resistant containers, but prolonged exposure to extreme heat or cold may temporarily affect its density. Allow the bottle to equilibrate to 15°C for 24 hours before use if shipped under non-controlled conditions.
5. What documentation is provided with each bottle?
Every unit includes a Certificate of Analysis (CoA) with batch-specific data, traceability information, and uncertainty statements. The CoA also provides detailed storage instructions and recalibration recommendations for maintaining accuracy.
