3 ml syringe

@kristal I did something similar as well. Although mine are 25G 25mm, and I used that for BAC draw, breather, and putting into the pep vial. However I did get some 35mm ones as drawing from a 3mm vial, I can get the pep juice from the bottom of the bottle. If I had to do it again, I would have gotten smaller ones for the breather. But will use these before that

I usually use 25g needles for reconstitution but 22g is probably fine. I think that is a bit large for loading cartridges. you can always buy thinner gauge needles if you think 22g is too big. I use 30/31 gauge for venting and loading carts, but that is very thin. The challenge going too thin is that it can be hard to draw and load, especially if the solution is viscous.

22g can “plug” (cut a hole) the top of a pen vial. I’ve had it happen with a 23 as well. I’d use the larger to draw and switch to a smaller gauge, like 27, to fill the pen vial. Cheaper to buy additional luer tips than buy new syringes.

I switch to 27 when I filter into vials just to keep the puncture smaller. Makes it a bit harder to pull out air for vacuum but it works fine.

I JUST bought some myself!
Using it for when I pull out multiple peps from multiple vials at once, switch to a fresh 30 guage and smoooooooth sticking for Mista Ratasuarus Rex! -

@kristal I'm going to start using my breather needles. they are very small 30g x 1/2 inch and they are luer lock. They fit my 3 and 5ml syringes.

@kristal FYI, I just reconstituted some Cartalax using breather and it's too small. Stick with a bit bigger needle. Filter had a hard time with it and I was real careful but not worth the effort or chance of breaking it.
-
These are what I use for reconstitution and breather needles, a 25Ga-1 1/2in needle and a 30Ga-5/16in.
-
I like the 31 ga 1-1/2” version for loading pens. It lets me get every drop out of the vial and is a tiny puncture in the cart.
Yes, it is a very slow draw so you have to be patient.
-
Yeah, testosterone sucks with a 31. But it is what it is...
My I ask what you use for testosterone? I'm looking at getting away from where I get my injections. I pay $600 for three months.

Hi,
just used a 3ml syringe for first time when drawing bac water/reconstituting and when i inserted into the vial the plunger dropped expelling the bac into the vial at a way faster rate than i usually reconstitute.
A small amount of bubble appeared but dispersed almost immediately.
Sorry for the stupid question but is that why breathers are used, to reduce vacuum pressure? and would the rapid rate/bubbles affect the quality of my research results? -

Even though some people don't mind the fast fill, I hold that plunger somewhat in place and slow it down. If you didn't insert a breather needle to the side of where you're placing your 3ml syringe needle, give that a try; it won't stop the plunger from dispensing but makes it easier.
