Air Into Vial

DPSCT

Veteran Member
EVO V.I.P.
Do you guys normally inject air into the vial to make drawing up the solution easier?

I have a vial of test that I will be using for 10 weeks - should I inject air each and every time I draw solution from that vial?

How much air should I normally inject into the vial prior to drawing up the solution?

Thx!

Nope. Never have.
 
I inject as much air into the vial as I plan to pull liquid back into the syringe. I have been doing it that way for almost 20 years because when I learned how to inject that was how I was taught.
But my wife has been in the medical field since the mid 90’s and owned her own practice for 10 years, she doesn’t inject air into vials when she does it, as far as I have seen.

You should not inject air into the vial, whats inside the vial should be sterile = so if you inject air you're adding air-borne bacteria which can give you an infection. Please dont add air into the multi use vial. Unsafe.
 
Like said above I inject as much air into the vial for how much oil I will pull out. Doesn’t seem like it makes a difference though.
 
No I have not done that before. Wouldnt recommend.
 
My old TRT doc recommended it and I've seen it in plenty of instructional videos. But drawing with 21g needles i have no issues.

I guess maybe if you are drawing with a smaller needle it may help. It does make drawing effortless because the pressure from the air pretty much pushes the oil into the syringe
 
If I am going to draw more than one compound into a syringe I do inject air into the vials. Just the amount that I am going to draw. This gets rid of the vacuum effect of pulling the oil back into the vial.
 
You'll make drawing a heck of a lot easier on yourself if you pressurize the vial with air first with an equivalent amount of air to oil you plan to inject. Then once the oil amount enters the syringe you reach pressure equilibrium. If you go to just pulling the oil right away you are trying pull the oil and create a vacuum in the vial where the oil was, creating more backpressure. Maybe its the engineer in me but it sure makes things much easier and makes total sense to use pressure to your advantage rather than working against it
