I have powdered stains that are probably 10 years old. I date dry chemicals when received and put a 10 year expiration date, if no expiration date is provided by the company. This has satisfied all my inspectors so far. I have discarded all the stains and chemicals we do not use anymore through a lab wide discard.

I have gone through them and just have what I need for the special stains that we do in house. does anyone know do they put expiration dates on dry chems. we have things like light green, biebrich scarlet, periodic acid. I really hate to get rid of all of this but he thinks I should. what are others doing about this? I can see after you have made up things to not keep it long but dry I know many yrs ago the biological stain commission thought it would be meaningless and arbitrary to put expiration dates on stains. it would me more important to maintain a record of the use of the powdered stain. which is what we do when we do the stain with our controls. anyway just wondering if there were any thoughts out there about this. anita dudley providence hosp mobile alabama _________________________________________________________________ See how Windows Mobile brings your life together-at home, work, or on the go. http://clk.atdmt.com/MRT/go/msnnkwxp1020093182mrt/direct/01/________________ _______________________________ Histonet mailing list [email protected] http://lists.utsouthwestern.edu/mailman/listinfo/histonet ***** CONFIDENTIALITY NOTICE ***** This message contains confidential information and is intended only for the individual named.
