A: Perhaps this company doesn't have an export license?

**Q: Does refrigeration after opening extend life of solutions?**
A: I never had and it's been fine.

**Q: Would the buffer solutions and storage solution work with the Extech pH meter?**
A: I would think it would work with your meter providing what you are trying to buffer falls within that range. The storage solution should work with all meters. 
  I would contact Extech and confirm with them to be 100% certain.
