Quality Control

Our Sodium Acid Oxalate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Production adheres to relevant analytical standards, and each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles. We support customer requirements for specific grades, including reagent and technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
