Thanks for your question.
First you put the needle on the syringe.
The correct technique will be:
Then you insert the needle in the bottle through the lid.
Then you should draw in the liquid in the syringe.
Now there may be bubbles in the liquid within the syringe.
This can be eliminated by gently stroking the syringe.
Once the bubbles come up and liquid below, you can push out the air bubbles.
Now even if you get few bubbles inside your vein, that will not cause any problem since the size is tiny.
This is safe to use as long as you are keeping them sterile.
I put the needle lid back on the second one I tried. Is that sufficient to keep it sterile? That was about 5-10 minutes ago.
yes it is if you did not touch the needle and cleaned the bottle lid with alocohol wipes.
No, I didn't clean the second bottle lid. I had done so on the first one and thought maybe that was wrong and why I got the bubbles.
no you should clean the lid every time before using it.
So could I use the first bottle? The liquid is back in there and did clean that lid before I used it. But I might have put it back in and drawn it out a second time. So would that mess that one up too?
yes you can use that
should not be a problem.
thanks so much
