Electroformed nickel tubing

NEW! 360 µm OD / .001" ID
Internal surface with 1-2 microinch finish
Minimum carryover potential
Smallest ID's on the market - custom sizes available
Precise internal volume
Ideal for transfer lines, sample loops, columns, restrictors, and fixed flow arrays

Our Microbore EFNi tubing is made by electroplating nickel over a diamond-drawn mandrel in a continuous process. When the mandrel is removed from the tubing, an internal surface with a mirror-like 1-2 microinch finish remains. The ductile nature of nickel allows the tubing to be easily manipulated. Unlike glass- or silica-lined stainless, EFNi can accept tight bends and cutting without heating, and does not release damaging glass fragments or silica particles.

Comparison photos

A comparison of the interiors of EFNi, Nickel 200 tubing, and Type 316 stainless tubing shows the quality of the electroformed nickel tubing surface. (All photos are x500 magnification.) The rough interior surface of the mill-drawn Nickel 200 tubing has potential for carryover or cross contamination, and both the Nickel 200 and the stainless steel contain pits, voids, striations, and particles - problems which intensify as the ID decreases.
