Quality Control

Our Sodium Oxalate-13C2 is manufactured under controlled conditions to ensure exceptional isotopic and chemical purity, meeting the stringent requirements of analytical and research applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing parameters such as isotopic enrichment (atom % 13C), chemical purity (by HPLC/NMR), and trace impurity profiles. We adhere to rigorous quality standards to guarantee batch-to-batch consistency and reliability for your critical research and diagnostic needs.

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). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which can affect stability and purity.
