1. A Nuclear Magnetic Resonance (NMR) tube comprising:
a tube body comprising a closed bottom end, an open top end, an inner surface that defines a cavity, and an outer surface;
a first material deposited onto the outer surface of the tube body to form a marking area, the marking area comprising a bottom end and a top edge; and
a second material deposited onto the outer surface of the tube body to form a locking ring positioned between the top edge of the marking area and the open top end of the tube body, wherein the top edge of the marking area is spaced apart from a bottom edge of the locking ring so that a portion of the outer surface of the tube body located between the marking area and the locking ring is exposed.
