Product Overview
This high-precision density standard (0.6791 g/ml at 50°C) is a NIST-traceable certified reference material designed for accurate calibration of laboratory instruments. Formulated with ultra-pure components, it ensures minimal batch-to-batch variation and long-term stability, making it reliable for critical measurements. The liquid form allows easy handling and precise dispensing, while its sealed packaging prevents contamination and evaporation. Compatible with most densitometers, pycnometers, and hydrometers, this standard meets ISO 17034 and ISO/IEC 17025 requirements, guaranteeing traceability and compliance with international standards. Its temperature-specific certification (50°C) eliminates the need for complex corrections, simplifying workflows in quality control, research, and industrial labs. The 100 ml pack size provides sufficient volume for repeated calibrations without frequent replacements.
FAQs
1. What is the shelf life of this density standard?
When stored unopened in its original container at room temperature, this density standard remains stable for 24 months from the date of manufacture.
2. Can this standard be used with digital densitometers?
Yes, it is fully compatible with both digital and analog densitometers, provided the instrument operates within the specified temperature range of 50°C.
3. Is recalibration required after opening the bottle?
No recalibration is needed if the bottle is resealed properly after each use. However, avoid prolonged exposure to air to prevent evaporation or contamination.
4. What alternatives exist for different temperature requirements?
For calibration at other temperatures, consider density standards certified at 15°C, 20°C, or 25°C, depending on your lab’s operating conditions.
5. How should this standard be disposed of after use?
Follow local laboratory waste disposal guidelines. As a non-hazardous liquid, it can typically be disposed of as standard chemical waste, but always verify with your institution’s protocols.
