Hi Pamela,

Just to re-iterate our phone convesation for the benifit of our Chemtalk Viewers,

Liquid Nitrogen Dewars, don't need to be primed, I'm not sure where the information originated from but this is not the case. Once the Dewars are manufactured they just simply need to be filled with N2.

Cheers,
