Chris -

Randee Kline wrote an answer to a similar question, which was published
the April 1999 ASCP "Laboratory Medicine." (under Q&A section)

Her answer was, in a nut shell, it is very difficult to "standardize"
shelf life of chemicals, due to how they are stored, how often they are
reused, the lab's temperature/humidity, under what conditions the
were shipped, etc.

As John Kiernan stated in his reply, his lab has found they need to use
different shelf life times compared to the some chemicals found in the
list of shelf life times found in Charles Churukian's book.

However, if you NEED some starting point, start with Charles' list, and
modify as you know what happens in your lab. That's what I did in the
student lab. (This also helped my students to see that shelf life
and the need to QC their own chemicals in their own lab.)
