As an accredited RESOMER R 203 H Bioresorbable Injectable Poly(D,L-lactide) factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | The chemical is packaged as 5 g in a securely sealed, labeled glass bottle for laboratory use. |
| Container Loading (20′ FCL) | 20′ FCL loaded with RESOMER R 203 H bioresorbable injectable poly(D,L-lactide), securely palletized in sealed drums under dry, controlled conditions. |
| Shipping | RESOMER R 203 H is shipped as a non-hazardous, bioresorbable poly(D,L-lactide) powder in tightly sealed, moisture-barrier containers, typically under nitrogen, at ambient temperature. No UN number, hazard class, or packing group is required. Protect from moisture, heat, and light; store at -20°C upon receipt. |
| Storage | Store RESOMER R 203 H in its original, tightly closed, moisture-proof container under cool, dry conditions. Recommended storage is 2–8°C, or −20°C for extended periods, protected from light, heat, and moisture. Before opening, allow the sealed package to equilibrate to room temperature to prevent condensation. Avoid repeated temperature cycling, as moisture uptake can hydrolyze the polyester. |
| Shelf Life | Shelf life is 2 years when stored unopened at −20°C, protected from moisture, heat, and light; see label expiry. |
