Product Overview

This density standard (0.7893 g/ml at 20°C) is a high-precision reference liquid designed for calibrating laboratory instruments such as densitometers, hydrometers, and pycnometers. Formulated with ultra-pure components, it ensures consistent and traceable measurements, meeting stringent lab requirements. The solution is chemically stable, resistant to evaporation, and packaged in airtight containers to maintain integrity over extended periods. Its certified density value at 20°C aligns with international standards, making it a reliable choice for quality control and research applications. The low thermal expansion coefficient minimizes temperature-induced errors, while the non-corrosive nature ensures compatibility with glass and metal apparatus. Whether used in routine calibrations or critical experiments, this standard delivers repeatable results, reducing variability in density-related analyses. The batch-specific certification guarantees accuracy, and the user-friendly packaging simplifies handling and storage.

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 in its original, tightly sealed container at room temperature.

2. Can this standard be used with automatic densitometers?

Yes, it is fully compatible with both manual and automatic densitometers, provided the instrument is calibrated to the reference temperature of 20°C.

3. Are there alternatives for higher or lower density ranges?

Alternative density standards are available for ranges outside 0.7893 g/ml, including 0.692 g/ml (hexane) and 1.000 g/ml (water), depending on specific calibration needs.

4. How should this standard be stored to maintain accuracy?

Store the bottle upright in a cool, dry place away from direct sunlight and heat sources. Avoid freezing or exposure to temperature fluctuations.

5. Is this standard traceable to national or international references?

Yes, the density value is traceable to NIST (National Institute of Standards and Technology) or equivalent international metrology standards, as documented in the certificate of analysis.
