We use zero or 5th grade from Airgas. You can call Airgas and ask for the % for zero and 5th grade.

Subject: AMMRL: Helium Gas Specification for Refilling Purpose
Dear all,
which Helium-Gas Cylinder do you use for refilling the magnet (i.e. to give slight pressure onto the refill dewar)?
Is the specification of 99.996 % sufficient for this?
Which experiences do you have?
Thanks!
Yours
