Quality Control

Our dendrimer solutions are produced and tested under strict quality protocols to ensure batch-to-batch consistency and purity. Each lot is characterized using advanced analytical techniques including Gel Permeation Chromatography (GPC) for molecular weight distribution, Nuclear Magnetic Resonance (NMR) for structural confirmation, and titration for functional group analysis. A comprehensive Certificate of Analysis (COA) detailing purity, concentration, solvent content, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). Due to the highly volatile nature of the methanol solvent, ensure containers are securely sealed and stored in a well-ventilated area away from heat and ignition sources. For long-term stability, consider storage under an inert atmosphere.
