For us, the bigger challenge is educating researchers to use dewars rated for their cryogenic liquid and that Thermos bottles don't meet those guidelines.
No video, but I recall reading this story a while back about someone trying to get rid of a thermos with dry ice in it after the lid got stuck. I have no idea if this is a true story or made up:
Jeff
Does anyone have a good reference for the safety of Dewar flasks?
Has anyone set limits on how long a Dewar flask may be in service before it must be replaced? What are those limits? What are they based upon?
Does anyone have a good video of a Dewar flask implosion?
Thanks,
Christina
