[3DEM] dry dewar

Dear colleagues,

I want to send vitreous samples in a “dry dewar”, i.e. a dewar in which
liquid nitrogen is absorbed in a porous material. Since the samples are in
gas phase, I am concerned that they always stay below the devitrification
temperature. Has anyone transported vitreous material in such a dewar? Did
the samples stay vitreous?

Best regards,
Benoît
