Re: bubbles

Hi,

I boil my DI water for 15 minutes (timer is always set) the day before I use it.  I
keep it capped in a 2 Liter flask and have  no problems wtih this at all.  I have at
times (such as coming back from a holiday) had to use DI water straight from the tap
and I invariably get those pesky bubbles.  Boiling does two things... 1) drives off
the gasses that produce the bubbles and 2) sterilizes the water.  I also add 100 mL
95% ETOH to my water bath (1800 mL boiled DI water) and I still have no problem with
bubbles.
