how to draw juice out of the bottle. the proper way

[Sub-Zero]

If you want to draw 1cc out of the vile, pull plunger back one cc full of air. Put needle in vial, and push 1cc of air into vial of gear. Then, draw 1cc of oil and pull needle out.

That is the "proper" way to draw oil...
You put the air in the vial to keep the pressure the same or something.

lol yep, its fluid dynamics, or mechanics, or physics, or just plain fucking logic...

how are you even able to draw once there is a build up of negative pressure in the bottle???

If you draw with a 20g and shoot with a 25g you should draw it out of the multidose vial to where the ring of the rubber plunger is below the 1ml marker on your barrel. (so essentially you're slightly under 1ml)

When you put on your 25g needle it should be perfectly at 1ml. Oil contained within the 20g needle displaces quite a bit more volume than the 25g needle (area of a circular cross section has a diameter^2 term in it).

yeah thats what i do, but it seems that you forgot the step of pulling out of the bottle, and then drawing back a tiny bit more to get the oil that was in the 20g

I crack it like an amp, aspirate it up, then switch the tip of the pin to a fresh one.

I love this place.

You should see me squinting one eye tilting the vial with the right amount of light behind it then strategically angling the tip of the needle to suck up ever last bit near the cap.
