I think it is well known among people who have a clue that the filling is
always done the same.  But for some funny reason, I personnally get a warm
fuzzy feeling from a lot number than can be traced.  Now I know that is no
guarentee either, but for the buck extra, I 'll splurge.  I know my supplier
treats all bottles identically when they come in (they are drained and
purged) but i am not sure if all suplliers do this for industrial.  I think
this is required for medical.  Anyway, I still prefer gas in a botlle marked
medical, be it o2 or he2.
