As an accredited Polyethyleneimine factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Polyethyleneimine is packaged in a 500 mL white HDPE bottle with a secure screw cap and hazard labeling for laboratory use. |
| Shipping | Polyethyleneimine is shipped in tightly sealed, corrosion-resistant containers due to its hygroscopic and corrosive nature. It must be stored away from acids, oxidizers, and moisture. During transportation, containers should be clearly labeled, kept upright, and handled with care, following all relevant chemical safety and hazardous material regulations. |
| Storage | Polyethyleneimine should be stored in a tightly closed container in a cool, dry, and well-ventilated area, away from incompatible substances such as strong oxidizers and acids. Protect the container from physical damage and moisture. Store at room temperature and avoid heat and sources of ignition. Always label containers clearly and ensure proper secondary containment to prevent spills or leaks. |
