Injector pump for the Reagent Robot: https://hackaday.io/project/4197 Turns out these do all the valving work we need. Part No.: 79004 Qosina Medical HPLC Dual Check Valve, 3 PSI CP, Male Luer Lock with Swivel Nut Outlet Port, Female Luer Lock Inlet Port and Female Luer Lock Control Port http://www.qosina.com/dual-check-valve-high-pressure-male-luer-lock-with-swivel-nut-outlet-port-female-luer-lock-inlet-port-and-female-luer-lock-control-port-79004 Cost should be less than a dollar each, but the trick is finding a source that will sell in low quantities. You can easily find a case of several hundred, but never 1. I got lucky with an eBay listing, which wasn't for this, but this is what was delivered. The injection tip is an 18 gauge 90' curved blunt tip for Luer lock syringes. Those are more commonly available. Again, I found these on eBay. I created this video with the YouTube Video Editor (https://www.youtube.com/editor)
