Recommend storage |
Stored in a cool and dry place without sunlight, a refrigerator is recommended. Temperatures (2-8°C) Notice: PLGA with intrinsic viscosity below 0.3 is powdered and will be melt at 18-22 °C. |
||
Shelf life |
When stored in the original packaging at low temperatures (2-8°C), PLLA keeps its initial properties for at least two years. |
