Quality Control

Our Poly(Spiropyran-Glutamate) is manufactured under controlled conditions to ensure batch-to-batch consistency and high performance. Quality is verified through a suite of analytical techniques including Gel Permeation Chromatography (GPC) for molecular weight distribution, NMR for structural confirmation, and UV-Vis spectroscopy to validate photochromic activity. A comprehensive Certificate of Analysis (COA) detailing purity, degree of functionalization, and key performance metrics is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic and strictly light-sensitive nature, the material must be handled under inert atmosphere or dry conditions when opened and shielded from all light exposure during storage and transfer to prevent degradation and moisture absorption.
