The tubing must be cut squarely to prevent possible problems. Square
ends are easier to insert through the ferrule and will decrease dead
volume.
Electrochemically machined steel tubing should be used throughout
the plumbing system. Electrochemically machined tubing has flat,
burr-free ends, and is free of cutting residues. This tubing is available
pre-cut through many chromatographic supply distributors in
assorted lengths.
A less desirable alternative is to purchase a tubing cutter designed to
handle steel tubing. For quick fixes, the tubing may also be cut by
hand.
Wear goggles to perform the following procedure.
• Fine jewelers file
• Protective eyewear
• Two pairs of pliers
1. Using the jewelers file, score the tubing around its entire circum-
ference.
2. Secure the tubing with pliers on either side of the score line with
approximately 1.5 mm between each pair of pliers and the score
line. Do not squeeze the tubing too tightly, as this will flatten or
deform its exterior.
3. Bend the tubing back and forth to crack it at the score line.
4. It may be necessary to deburr the outer tubing ends with the file.
Make sure the tubing ends are clean and the inner bore is clear
before installing the cut tube.
It is often impossible to remove a burr that blocks the inner bore.
