Product Overview
The density standard (1.5775 g/ml at 25°C) is a high-precision reference material designed for calibrating laboratory instruments requiring accurate density measurements. Certified to meet international standards, this liquid density standard ensures traceability to NIST (National Institute of Standards and Technology), providing confidence in calibration accuracy. Its chemical stability and resistance to evaporation make it ideal for long-term use in controlled lab environments. The standard is pre-validated for consistency, eliminating the need for in-house verification and reducing procedural errors. Packaged in a durable, leak-proof container, it minimizes contamination risks while maintaining integrity during storage and handling. Compatible with a wide range of densitometers, pycnometers, and hydrometers, this standard supports seamless integration into existing workflows without requiring additional adjustments. The 100 ml pack size offers an optimal balance between sufficient volume for repeated calibrations and practical storage. Whether used in routine quality control or high-stakes research, this density standard delivers reproducible results, ensuring compliance with ISO and GLP guidelines. Its non-hazardous composition further simplifies handling and disposal, aligning with lab safety protocols.
FAQs
1. What is the shelf life of this density standard?
The density standard remains stable for up to 24 months from the date of manufacture when stored unopened in its original container at room temperature (15–25°C). Avoid exposure to direct sunlight or extreme temperatures to preserve accuracy.
2. Can this standard be used with digital densitometers?
Yes, this density standard is fully compatible with digital densitometers, including those from major brands like Anton Paar and Mettler Toledo. Its certified value ensures precise calibration across both manual and automated systems.
3. Is recalibration required after opening the bottle?
No recalibration is needed if the bottle is resealed properly after each use. However, we recommend verifying the density periodically if the standard is exposed to air for extended periods, as minor evaporation could affect accuracy.
4. Are there alternatives for higher or lower density ranges?
For densities outside this range, we offer standards from 0.692 g/ml to 2.998 g/ml. These are available in similar pack sizes and adhere to the same CRM grade specifications for consistency.
5. How should I dispose of this density standard?
This standard is non-hazardous and can be disposed of according to local laboratory waste regulations. Neutralize with water if required, then discard in approved liquid waste containers. Always check your institution’s disposal guidelines for specific protocols.
