[Histonet] Chemicals with no expiration

[Kathleen Bess]

Hi all,
 
First time using histonet- I read earlier that reagents/chemicals used in the lab with no expiration date are to be labeled with an expiration date of 5 years after having been opened. Is there literature on that? I need to update my policy and prodedure for CAP. Also, this maysaound silly, but do you label your DI water too?
 
Thanks in advance,
