Product Overview
This 2000 µS/cm conductivity standard is a high-precision solution traceable to NIST (National Institute of Standards and Technology), ensuring unmatched accuracy for critical lab applications. Formulated with ultra-pure reagents, it provides a stable reference point for conductivity meter calibration, eliminating measurement drift and variability. The solution is designed to meet stringent research-grade requirements, offering consistent performance across temperature variations. Its low ionic interference and long-term stability make it ideal for routine instrument verification, quality assurance protocols, and process control in analytical laboratories. The 500 ml pack size balances convenience with cost-efficiency, reducing frequent replenishment needs while maintaining freshness. Each batch undergoes rigorous testing to guarantee compliance with international standards, with certification documentation available for traceability. The solution’s homogeneous composition prevents sedimentation or phase separation, ensuring uniform readings throughout its shelf life. Compatible with most conductivity probes and meters, this standard delivers reproducible results across different instrumentation platforms, making it a versatile choice for multi-lab environments.
FAQs
1. What is the shelf life of this conductivity standard?
The unopened bottle has a shelf life of 24 months from the date of manufacture when stored under recommended conditions. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used with portable conductivity meters?
Yes, it is fully compatible with both benchtop and portable conductivity meters, provided the probe is properly calibrated and the temperature compensation settings are adjusted.
3. How should this solution be stored to maintain accuracy?
Store the sealed bottle at room temperature (15-25°C) away from direct sunlight and moisture. Avoid freezing or exposure to temperature fluctuations above 30°C.
4. Is recalibration required after opening the bottle?
No recalibration is needed if the bottle is resealed properly after each use and stored correctly. However, verify the solution’s integrity if exposed to contamination or extreme conditions.
5. What documentation is provided for traceability?
Each bottle includes a certificate of analysis with batch-specific data, NIST traceability statement, and expiry date for compliance and auditing purposes.
