Quality Control

Our Fluorescent Red 635 Reactive* is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for color strength and emission wavelength, and reactive group content analysis. A Certificate of Analysis (COA) detailing purity, physical properties, and performance specifications is provided with every shipment to ensure consistency and compliance with your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed and stored under dry conditions to prevent degradation and clumping.
