Cryogenic temperatures....

....via vapor injection method are usually at -295F. to -300F.

Processes considered 'deep' cryogenic treatment achieve -320F., which is the boil-off point for LN2. There *is* a qualitative difference between deep treatment and vapor treatment, and one can hear it.

Jena Labs has been using deep cryogenic temperatures for many years, with some of their parts going through an immersion process (parts literally soaking in the LN2). Jennifer claims to achieve an even lower ambient temperature, which others dispute, but there is no question she knows what she is doing.

Using dry ice would not be considered cryogenic treatment by any means, but if it achieved a low enough level, might be considered "deep refrigeration" in the right vessel. One's home freezer would not be considered deep refrigeration by any stretch. Some claim to hear a qualitative difference with CD's and DVD's treated this way....I do not doubt their experience. But the treatment is NOT permanent, like cryogenic treatment would be.

I hope this information answers your question(s).
