Hi Perry,
Originally Bruker would purchase them from Wilmad separately from Oxford,
but I don't see the "thin wall" He Dewar on the Wilmad website. You might
try calling them because ColdEdge tech also sells their cryogen free unit
with the same Dewar which is another option to purchase from, but they may
be just as expensive.
Cheers,
Chuck
