As an accredited RESOMER RG 505 Bioresorbable PLGA Drug Delivery Grade factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Packaged in a 1 g amber glass vial, sealed under inert atmosphere, labeled RESOMER RG 505 Bioresorbable PLGA Drug Delivery Grade. |
| Container Loading (20′ FCL) | 20′ FCL: palletized, moisture-protected drums of RESOMER RG 505 Bioresorbable PLGA Drug Delivery Grade, stored dry, ambient, away from heat. |
| Shipping | RESOMER RG 505 is shipped as a non-hazardous, moisture-sensitive solid polymer in sealed, desiccant-containing containers. Transport at ambient temperature unless otherwise specified; protect from heat, moisture, and contamination. No special dangerous-goods classification typically applies. Upon receipt, store at -20°C per manufacturer instructions and local regulations. |
| Storage | Store RESOMER RG 505 in a tightly closed, moisture-proof container in a dry, cool place, preferably at −20°C for long-term storage (2–8°C short-term). Protect from heat, light, and humidity; use an inert atmosphere (nitrogen/argon) if possible. Allow to equilibrate to room temperature before opening to prevent condensation. Avoid repeated temperature cycling and keep container sealed when not in use. |
| Shelf Life | Shelf life is typically two years when stored unopened at −20°C, protected from moisture, per manufacturer recommendations. |
