PE - Well I came up with the nozzle config based on our discussions, so I'm glad it is close to what you were telling me.

I forgot to mention that with the pump running at about a 1 ml/minute, it will squirt a pretty steady stream of liquid out the tip of the nozzle and across the lab bench due to the small inside diameter of the teflon tubing! Doing that is actually a great way to see how constant the pump pressure is.

Also, I bought a lot of tubing (both teflon/ptfe and stainless) from smallparts.com. I see they are part of Amazon now...
