Quality Control

Our Infrared Absorber 858 is produced under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is subjected to comprehensive analytical testing, including spectrophotometric purity verification and functional performance checks. A Certificate of Analysis (COA) detailing key specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and hygroscopic (moisture-sensitive); therefore, containers must be kept sealed in a low-humidity environment to maintain product integrity.
