Injection Question

**Jman123** · 07-20-2011, 03:40 PM

I saw a video that recommended leaving a small air bubble in the bottom of the syringe so that it would push the remainder of oil out of the needle at the end of the injection. Is this advisable or is it dangerous? Should you just let that bit of oil go to waste? It couldn't be much either way. Thanks.

What video is this? I don't understand how you can leave a small air bubble at the "bottom" of the syringe. Please advise because I've always believed that no matter what you'll lose a bit from the oil left in the base of the pin.

The OP is referring to the plunger side as being the bottom. If the plunger side is higher than the needle during the injection, the bubble will float to the top.

its fine, but you still will be left with that little amount in the nozzle no matter what, ive used as much as 1.5ml air to try and push it through, makes no diff

so how much we talking about?

a small amount at the end of a needle, X pins/week x 12, X cycles/year.

when you add it all up, does it even come out to $10?
