Product Overview
This density standard (2.6011 g/ml at 20°C) is a high-precision reference material designed for accurate calibration of density meters, pycnometers, and other analytical instruments. Manufactured under strict quality controls, it ensures NIST-traceable accuracy with minimal batch-to-batch variation, making it a reliable choice for laboratories requiring consistent results. The solution is stable under standard lab conditions, resistant to evaporation, and packaged in a sealed, tamper-evident container to prevent contamination. Its certified composition eliminates the need for in-house standardization, saving time and reducing errors. The low thermal expansion coefficient ensures measurements remain precise even with minor temperature fluctuations. Ideal for routine quality checks or critical research applications, this standard adheres to international metrology guidelines, providing confidence in your instrument’s performance. The 100 ml pack size offers sufficient volume for repeated use without frequent replenishment, balancing cost-efficiency with practicality.
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 at 15–25°C, away from direct sunlight and moisture. Always check the certificate of analysis for the exact expiry date.
2. Can this standard be used with digital density meters from different brands?
Yes, this NIST-traceable standard is compatible with all major digital density meters, including those from Anton Paar, Mettler Toledo, and Rudolph Research, provided the instrument supports liquid calibration at 20°C.
3. How should I handle the standard to avoid contamination?
Use clean, dry pipettes or syringes dedicated solely to this standard. Avoid touching the bottle’s opening or inner cap, and reseal tightly after each use to prevent moisture absorption or volatile loss.
4. Is recalibration required if the temperature deviates from 20°C during use?
Minor deviations (±2°C) have negligible impact due to the low thermal expansion coefficient, but for temperatures outside this range, apply the temperature correction factor provided in the certificate of analysis or recalibrate the instrument.
5. What alternatives are available if I need a different density value?
Equipped offers a range of certified density standards spanning 0.6–3.0 g/ml in 0.001 g/ml increments. Contact support for custom values or bulk packaging options tailored to your application.
