304 stainless steel, electropolished inside and out
Each tube is first hand-buffed to a No. 8 true mirror finish (Ra ≤ 0.05 µm), then electropolished on the outer surface and inside the lumen to Ra ≤ 0.38 µm (15 µin), the electropolished-finish benchmark used for pharmaceutical process tubing. The result is a smooth, bright finish with no machining burrs or rough spots for tissue and fluid to cling to, so lumens rinse clean faster and are easier to inspect during reprocessing.
