  Expiration date of bottled water

  Posted by Doreen on March 25, 2018 at 7:30 pm

  I have 5 ltr jerrycans with distilled and deionized water.
  I’m still not sure how long I can keep using these after opening.
  At work we throw the rest away at the end of the day (purified water - which we use for both sterile and non-sterile preparations).
  I hope I can use this a bit longer, as I don’t use 5 ltrs a day!

  Any suggestions?

  As long as you put the lid back on, I imagine you could use it until it is gone.

  What are you going to make?. 

  You can boil it before using it.

  @Perry
  Ok, thanks!  

  @DAS
  I use it for all my water containing formulas and to prepare buffer solution for the pH meter.
  I never boil the water nor do I heat & hold. Do you?

  Only if I use filtered tap water. 

  If you want to prevent contamination you can use this

  Ok, thanks for the tip.

  With purified water I meant sterilised and filtered water (no pyrogens, suitable for injections).
