I'm having trouble with the plunger folding like an accordion after just a few injections. Any suggestions? I've set it to half speed and that didn't solve the problem. This occurs when it is pulling a sample.

One of the two flat spots on top of the syringe needs to be flush with the white plastic backing. The black plastic halfway down the syringe body is meant to rotate in front of the syringe to keep it from moving around while operating.
What is the sample? If it's something really viscous the plunger may have trouble going back down. It may be necessary to dilute the sample in a solvent to reduce its viscosity.
The sample is usually a solvent as I use it to teach organic chemistry in a community college. We keep it basic to illustrate how a GC works.
