I would suggest dry ice (on top of something plastic on top of the metal
shelves), NOT liquid nitrogen. Dry ice is usually cold enough to bring our
cryostat to -28 C when it won't cool down past -24 C because of frost on the
compressor. I don't think it actually makes the cryostat colder than tha
Hi Louise
Not a very safe practice. I have heard of people using a bag of dry ice

information would be appreciated.
Thanks
