Packed Column Tubing
Restek offers a wide range of tubing choices for our packed columns, including
SilcoSmooth® (Siltek®-treated stainless steel), stainless steel, PTFE, nickel, copper, and
Hastelloy® tubing. SilcoSmooth® and stainless steel tubing are our two most popular
column materials. SilcoSmooth® tubing is an excellent replacement for fragile glass
columns. Stainless steel tubing works well with most applications for nonreactive
compounds.
SilcoSmooth® Tubing
If your analysis involves reactive compounds, you can use SilcoSmooth® tubing, which
combines the inertness of glass with the strength and flexibility of stainless steel. Made
from ultra-smooth, seamless 304 stainless steel and treated with the innovative Siltek®
process, SilcoSmooth® tubing can replace glass columns for virtually any application.
Stainless Steel Tubing
If you are analyzing hydrocarbons or nonreactive compounds, you can use our rugged,
flexible, and economical stainless steel columns. Restek® stainless steel columns are
made from high-quality welded and drawn tubing.
Hastelloy® Tubing
Hastelloy® tubing is a nickel-chromium alloy with excellent inertness. It is normally
used only for highly corrosive or oxidizing compounds or gases.
Nickel Tubing
Nickel tubing is often used for analyses of caustic or oxidizing compounds or gases.
Copper Tubing
Copper is a general-purpose tubing that is only recommended for inactive compounds.
PTFE Tubing
PTFE tubing is often used for reactive compounds or other special applications. Note
that this tubing is permeable to gases.
