Quality Control

Our Acidblue175 is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against stringent in-house specifications, which typically include parameters for identification, assay, shade, and solubility. A Certificate of Analysis (COA) detailing these results is provided with every shipment to guarantee compliance with your technical requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture.
