Copper tubbing from MC master

Is it 100% pure copper? Has anyone used it? Does it provide extra voltage?

It was in levista's ROP thread but AC told me that it would be best to get copper from lowes as he is sure it is 100% percent safe.


I'm building a new one for myself that's why

That is the right one for a solid piece or the one from Lowe's if you want hollow piece either one works, extra voltage, no.

You need "food grade" copper like the copper used by beer distilleries. It is hard to find and not cheap but there is no way I would put that refrigeration copper alloy anywhere near my nuts.
