What gauge breather needle to purchase?
-
I use 30/31g

@vpeptides The problem with that is blowing the plug out of the cartridge. Are you filling carts without a vent and not having the plug come out? That seems unlikely to me.
Please set a funny and sarcastic signature line. It brings me joy. Thank you for your attention in this matter.

@ResearchCat I was talking about a 3ml vial, not a cartridge. Didn't read the post carefully. I am a writer, not a reader, you know?

I don' use a breather needle. I inject the liquid through the filter, then detach the filter from the needle to let the extra air out.

@vpeptides All good! Thanks for clarifying. That makes sense.
-
@vpeptides How do you tell when all the air is out of the vial?
-
@vpeptides Ok, does it hiss, pop, any indication?
@Eleanor Long story: It hisses when I slightly release the needle from the filter to equalize the pressure. Then I reconnect it and disconnect the filter from the syringe to add more air into it, then reconnect again and push to let whatever is still in filter to go through. Then disconnect again the needle.

Thanks all! So excited to get started with filtering and pens!
