Packing, Shipping and Storage Instruction

The suggested storage temperature shown on our website is at -20℃, but the package are usually shipped at room temperature, so you may feel confused and worry about the stability of the compounds, hope you could get relaxed after reading the following Packing Instructions:
1. By "the suggested storage temperature is at -20℃", we mean you should keep the left compound at -20℃ after you open the vial and could not use the compound out at one time.
2. Most of our compounds are in dry powder and of very good stability, so it is safe during the transition at room temperature and it could last for 1-2 weeks and even more.
3. For some specific sensitive compounds, we will ship them with dry ice or blue ice.
4. By the way, once diluted, the compound should be used out at one time, or it may go worse even if it is stored at -20℃.
