## Questions & Answers

**Q: Most of these kits are currently out of stock.  is there an eta or more stock, please?  thanks.**
A: I don’t have any information you can call apera instruments they should be able to help you with your inquiry.

**Q: Why can't i bay this calibration kit and get it delivered to silkeborg denmark, when i can bay the apera pc60 and get it delivered. it doesn't make se**
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.

These are the go-to reference solutions for testing the acid levels in wine. This brand has a 2-year expiration date. The coloration of these references makes it easy to not mix them up.
