So here's a quick first test using 3 bar in the first seconds then 6 bar. At 6 bar there is too much pressure at start but thats solved now, there was a 10m hose in between the compressor and the 1/8 inch tubing. There was to much pressure building up there. Now I need some sample sizes of short, blunt luer-lock needles but unfortunately they come in boxes of 100 pc.

The output, including sharp starting, stopping and no real oozing looks totally usable! Nice!
ReplyDeleteB.t.w. I played with injection needles too. You can saw them to be shorter. Just make sure you remove the burrs with some sandpaper (outside) and steel wire (inside). A shorter nozzle will have significantly less friction and allow you to use less pressure with a higher flow rate.
ReplyDeleteIf you're near Tilburg, I'd happily share some of my stash of needles (sounds like I have a drug problem?! ;) ). It would also be nice to see you again.
Hi Erik, you have luer lock needles? Am looking for a place where I can order various sizes of short blunt luer lock needles. Will probably order a few boxes of 25 needles.
