What you see in the figure is a Hamilton valve coupled to a pretty strong servo motor. Everything is held in place using a mounting that is 3d printed. Ok, so what can you do with a few syringe pumps and valves? Can you automate a flash chromatography system? What about making a DNA- or peptide-synthesizer? The guy in the photo there is on the way to being incorporated into my autotitrator.
This project needs some work. The 3d printed plastic parts should be replaced with stamped metal parts. This will give a sturdier, more robust platform. Let me know if you want me to get into that.
