Degassed Water

Post by labbassistant »

Hi all,

We've been asked to make up degassed water. We've had a quick google and found that it says to simmer for 20 mins and let cool. Our plan is to do this the day before and seal in a bottle where there is no air bubble to 'regas' the water.

Has anyone done this before?

Thanks

yes make sure there is no headspace. You could pop the bottle under vacuum in a desiccator also after cooling to be super sure however probably not needed.
