What are the pros and cons of using glass or metallic dewars/cryostats?

  1. Apr 13, 2012 #1
    My question is specifically with respect to holding LHe and using these containers as the environment for experiments (so not just for storage):

    Features to consider:

    Price
    Longevity
    Necessary associated equipment (I know this could be vague, but the LHe glass dewar would be surrounded by an LN2 dewar + equipment to pump on the LHe dewar. I'm not sure what is necessary with a metallic cryostat)


    I am trying to learn about metallic cryostats/cryogenics, so any information could be valuable. Linked examples would also really be appreciated!

    Thanks!
