Upchurch Scientific® seamless, precut stainless steel tubing is specially prepared for the exacting requirements of today’s analyses. We machine cut and polish each end, deburr the inside and outside edges and passivate the tubing.

Stainless Steel Tubing Passivation

Stainless steel is naturally self-passivating, forming an oxidation layer on newly created surfaces. Upchurch Scientific takes extra steps to ensure the chemical resistance of our stainless steel tubing by manually passivating before and after the tubing is cut into specified lengths (except in a few cases where size is prohibitive). In the pre-cut stage, the internal wall is acid passivated and flushed. After the tubing is cut, deburred and polished, the length is completely submerged in an acid passivation bath and again flushed clean. The table below summarizes the manual passivation steps performed for each size of our stainless steel tubing:

(Tubing) (Precut Passivation) (Postcut Passivation)
(.020” OD) (All) (All)
(1/32” OD) (All) (All)
(1/16” OD) (All) (All, except 25’ lengths)
(1/8” OD) (None) (All, except 3 & 5m lengths)

Following the passivation step, we flush reagent-grade methanol through each piece of tubing as a final rinse. Our thorough preparation and cleaning procedure guarantees tubing that is truly ready-to-use, with flat, burr-free ends and a clean finish – important in achieving zero-dead-volume connections and good chromatographic results.
