Product Overview
The 10 mg/L COD calibration standard is a high-precision solution designed for accurate chemical oxygen demand (COD) measurements in laboratory settings. This analytical-grade liquid standard ensures reliable calibration of COD meters and test kits, providing consistent and reproducible results for water quality analysis. Formulated with strict adherence to international standards, it guarantees minimal variability and maximum stability over time. The 500 ml pack size offers an optimal balance between quantity and shelf life, reducing the need for frequent replacements while maintaining freshness. Its ready-to-use liquid form eliminates the need for dilution or preparation, saving valuable lab time. The standard is compatible with most spectrophotometric and titrimetric COD measurement methods, making it versatile for various testing protocols. Each batch undergoes rigorous quality control to ensure accuracy within ±2% of the stated concentration, providing confidence in your analytical workflow. The solution is packaged in high-density polyethylene (HDPE) bottles to prevent contamination and degradation from light exposure. Whether used for routine environmental monitoring or research applications, this COD standard delivers the precision required for critical water quality assessments.
FAQs
