D Series Syringe Pumps: Model 500D
Section 2B 500D Liquid System Connection & Accessories
It is recommended that electrochemically machined steel tubing
be used throughout the plumbing system. Electrochemically
machined tubing has flat, burr-free ends for minimum dead
volumes and is free of cutting residues. Pre-cut, electrochemically
machined tubing is available through many chromatographic
supply distributors in assorted lengths.
A somewhat 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 with the following procedure. A jeweler’s
file, goggles, and two pairs of pliers are necessary for this operation.
To cut the tubing by hand
1. Wear goggles. Using a fine jewelers file, score the tubing
around its entire circumference.
2. Secure the tubing with pliers on each side of the score line,
leaving approximately 1 16" between each set of pliers and
the score line. Care must be taken not to squeeze the tubing
too tightly, as that will flatten or deform the exterior of
the tubing.
3. With the pliers, bend the tubing back and forth to cause
cracking at the score line. The bending should be done in
two places to reduce the chance of squashing the tubing.
4. It may be necessary to deburr the outside of the tubing
ends with the file. Make sure the tubing ends are clean and
the inner bore is clear before installing the cut tube.
Note
It is often impossible to remove a burr that blocks the inner
bore.
