Thanks. Just got an e mail from Pfertz saying that it can last several years if kept in a cool, dry place. Pfertz answered my question in about 20 min. Good business practice for them, I am impressed.

Hi Constantin,

The shelf-life of our micros solution is at least several years, possibly longer if it is always kept in a cool, dark place. Let me know if you have any other questions!
