Product Overview
This density standard (0.7223 g/ml at 25°C) is a high-precision reference material designed for calibrating laboratory instruments that measure density, including digital densitometers, pycnometers, and hydrometers. Manufactured under stringent quality controls, it provides NIST-traceable accuracy, ensuring reliable and repeatable results in critical applications. The liquid is formulated with ultra-pure components to minimize volatility and contamination risks, maintaining stability over extended storage periods. Its certified value is verified through multiple analytical techniques, including oscillating U-tube densitometry, to guarantee conformity with international standards. The 100 ml pack size offers sufficient volume for multiple calibrations while reducing waste, making it cost-effective for routine lab use. Compatible with most glass and plastic labware, this standard eliminates the need for frequent recalibration, saving time and reducing operational errors. Whether used in research, industrial QC, or educational settings, it delivers consistent performance across temperature-controlled environments.
FAQs
1
What is the shelf life of this density standard?
The product remains stable for 24 months from the date of manufacture when stored unopened in its original container at 15–25°C. Avoid exposure to direct sunlight or temperature fluctuations. 2
Can this standard be used with automatic densitometers?
Yes, it is compatible with most automatic and manual densitometers, including those from Anton Paar, Mettler Toledo, and Rudolph Research. Always verify instrument-specific requirements before use. 3
Is recertification available after opening?
Recertification is not provided post-opening, as contamination or evaporation may alter the density. For critical applications, use a fresh, unopened bottle or conduct in-house validation. 4
What materials are used in the packaging to prevent contamination?
The standard is supplied in amber glass bottles with PTFE-lined caps to minimize chemical interactions and light-induced degradation. The packaging meets ISO 8362-1 standards for CRM containers. 5
How does temperature affect the certified density value?
The certified value (0.7223 g/ml) is valid at 25°C. Density varies with temperature; use the provided temperature correction table or instrument software to adjust readings for other temperatures.
