Product Overview
The density standard (1.0755 g/ml at 25°C) is a high-precision reference fluid designed for laboratory calibration applications requiring exact density measurements. Formulated with NIST-traceable accuracy, this standard ensures consistent, reliable results across hydrometer testing, pycnometer verification, and other density-dependent procedures. Its chemically inert composition minimizes reactivity with common lab materials, while the stable formulation prevents evaporation or degradation over time. The 1.0755 g/ml value is certified at 25°C, eliminating temperature-induced variations that could compromise accuracy. This standard is particularly valuable in quality control environments where traceable, repeatable density measurements are critical. The liquid form allows for easy dispensing and cleaning, while the analytical grade purity guarantees interference-free performance. Each batch undergoes rigorous testing to confirm compliance with international standards, making it a trusted choice for research, industrial, and educational laboratories. The 100 ml packaging provides sufficient volume for multiple calibrations while maintaining cost efficiency. Unlike generic density standards, this product offers documented traceability and lot-specific certification, ensuring compliance with ISO and GLP requirements.
FAQs
1. What is the shelf life of this density standard?
When stored unopened in original packaging at controlled room temperature, this density standard maintains its certified accuracy for 24 months from the date of manufacture.
2. Can this standard be used with digital density meters?
Yes, the 1.0755 g/ml standard is compatible with all modern digital density meters, including oscillating U-tube and vibrating element types, provided the instrument is properly calibrated.
3. How should I dispose of expired density standards?
Follow your institution’s chemical waste disposal protocols. This standard typically qualifies as non-hazardous waste but may require special handling depending on local regulations.
4. What’s the difference between this and a 1.0000 g/ml water standard?
This 1.0755 g/ml standard is specifically formulated for calibrating instruments in the mid-density range, while water standards (1.0000 g/ml) serve as primary references. Using both provides broader calibration coverage.
5. Does the certification include uncertainty values?
The certificate of analysis provides both the certified density value and expanded uncertainty (typically ±0.0002 g/ml at 95% confidence), calculated according to ISO Guide 34 requirements.
