DIY Microinjector: Technical Part Checked!

Hey folks,

Today, I bought two ultra fine insulin needles of 1cc capacity to test on this EZ injector. After changing the plunger size, plugged in the cork on the plunger, testing the injection volume and speed, I finally managed to come up with an initial set of injection condition. Now, I just need to test it on the spider to see if worked or not. Otherwise, I need to further optimize it. Crossing fingers to this!
