Quality Control

Our Oxalic Acid is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. The product undergoes comprehensive analytical testing, including assay, heavy metals screening, and loss on drying, to meet relevant industry standards. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee specification compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
