RE: [Histonet] out dated reagents

From:"Joyce Cline"

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.

Subject: [Histonet] out dated reagents

hello all,  we were inspected the beginning of june by cap and one of our
deficiency was anp.21382.  it had to do with outdated reagents.  my director
want all of my dry chemicals gone!!!!   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.
