How about just using an adhesive color dot system?
Can use one dot to represent the year and second to represent the month.
Just a suggestion, its been a long day!

Hi all. I am hoping for some clever ideas on the best method to check for
expired reagents. We all know that we shouldn't use them, I'm sure we all
actively monitor this (right)! I must admit we occasionally have expired
reagents - a stain or buffer we haven't used in a while is in a cupboard or
fridge & it has expired. What do others do to monitor & prevent this from
happening? We have a weekly safety check that spot checks a certain # of
reagents for expiration, but we probably have thousands of reagents & don't
check every single bottle every week. Thanks for the input.
