Product Overview
This density standard (1.7470 g/ml at 20°C) is a precision-engineered reference fluid designed for accurate calibration of laboratory densitometers, hydrometers, and pycnometers. Formulated with ultra-pure components, it meets stringent quality control standards to ensure consistency across batches. The liquid maintains long-term stability under standard lab conditions, minimizing evaporation or degradation over time. Its NIST-traceable certification guarantees measurement reliability for critical applications requiring exact density values. The 100 ml pack size offers sufficient volume for repeated calibrations while maintaining cost efficiency. The standard is packaged in a chemically inert container to prevent contamination, with a tamper-evident seal for quality assurance. Compatible with most glass and stainless steel labware, it requires no special handling beyond standard laboratory practices. For optimal performance, store at controlled room temperature (20-25°C) away from direct sunlight and moisture sources.
FAQs
1. What is the shelf life of this density standard?
The product maintains its certified density value for 24 months from the date of manufacture when stored under recommended conditions in its original sealed container.
2. Can this standard be used with digital densitometers?
Yes, it is fully compatible with all major brands of digital densitometers, including Anton Paar, Mettler Toledo, and Rudolph instruments.
3. What is the typical uncertainty of this density standard?
The expanded uncertainty (k=2) is ±0.0002 g/ml, providing high confidence for calibration procedures.
4. Is this standard suitable for use in humid environments?
While the product itself is stable, prolonged exposure to high humidity may affect the container’s integrity. Use in controlled lab environments is recommended.
5. What documentation is provided with each bottle?
Each unit includes a Certificate of Analysis with traceability information, measured density values, and storage instructions.
