I don't know of any physical measurement lead to a real infinity,
except maybe supraconductivity.

Oh, there are lots if you look for them.
<http://en.wikipedia.org/wiki/Ideal_gas_law>
The state of an amount of gas is determined by its pressure, volume, and
temperature. The modern form of the equation is:
where p is the absolute pressure of the gas; V is the volume; n is the
amount of substance; R is the gas constant; and T is the absolute
temperature. n = pV/(RT)
At absolute zero kelvin, the amount of gas is infinite.
