Tubing comparison

Note the rough interior surface of the mill-drawn Nickel 200 tubing, which has potential for carryover or cross contamination. Observe as well the pits, voids, striations, and particles in the Nickel 200 and Type 316 stainless steel – problems which intensify as the ID decreases.
