Product Overview
This density standard (1.4136 g/ml at 20°C) is a high-precision reference fluid designed for calibrating density meters, hydrometers, and other analytical instruments. Formulated with ultra-pure components, it ensures long-term stability and batch-to-batch consistency, meeting ISO 9001 and GLP/GMP standards. The NIST-traceable certification guarantees accuracy within ±0.0002 g/ml, making it ideal for critical applications where precision is non-negotiable. The solution is pre-packaged in amber glass bottles to prevent photodegradation, with tamper-evident seals for integrity assurance. Its low viscosity ensures easy handling, while the non-hygroscopic nature minimizes evaporation losses. Compatible with most laboratory glassware and automated dispensing systems, this standard eliminates the need for in-house preparation, reducing human error. The accompanying Certificate of Analysis provides full traceability, including lot-specific data and expiration date. For optimal performance, store at 15-25°C away from direct sunlight and moisture.
FAQs
1. What is the shelf life of this density standard?
The standard maintains its certified accuracy for 24 months from the date of manufacture when stored unopened at 15-25°C. Once opened, use within 6 months for best results.
2. Can this standard be used with digital density meters?
Yes, it is fully compatible with all major brands of digital density meters, including Anton Paar, Mettler Toledo, and Rudolph Research instruments.
3. How often should I recalibrate my instruments with this standard?
For critical applications, weekly calibration is recommended. For routine quality control, monthly calibration typically suffices, though this may vary based on instrument usage and environmental conditions.
4. What alternatives exist for different density ranges?
We offer a complete range of density standards from 0.692 g/ml to 2.995 g/ml in 0.1 g/ml increments, allowing you to select the ideal reference for your specific measurement range.
5. Does this standard require any special disposal procedures?
While non-hazardous, the standard should be disposed of according to local laboratory waste regulations. The primary components are organic solvents, so check with your institution’s EHS department for specific guidelines.
