Drawing oil from vial- problems

[androjello]

Whenever I draw the Cyp. from the vial, a ton of air comes with it into the syringe and it becomes a pain in the ass.

I always inject the same volume of air into the vial as I want oil to be drawn out, but still I can barely even get the oil to come out.

Can anyone offer me advice or tips for easier drawing of the oil?

(I do invert the vial when drawing)

First, make sure your needle is securely attached to the syringe. Put a little extra air in the vial for the next draw...it won't hurt anything and will only help with the fill. Make sure that you don't bubble the air through the oil, i.e., don't submerge the needle when filling the vial with air. Then, invert the vial, make sure the needle tip is ALWAYS covered by oil and begin the draw...be patient. If you're using a 22 or 23 guage needle, it takes a little time.

I use a 22 ga. needle to draw up and switch to a 25 ga. for the injection. It draws easier and I don't have to worry about dinging the end of the needle on the rubber stopper before the injection. I've done hundreds of injections that way and never had a problem with air bubbles or anything else.

i use a 22 gauge and it dosn't take too long........... push the needle in as far as it can go.........oush out all the air and pull the needle back submerged in the oil............then draw slowly.............it only takes me about 20 seconds....... then change tips to wat ever u use........ i use a 25

do you guys mail order you needles or get them at the pharmacy?

I get the syringes at the local pharmacy.

Just to be clear, this is the procedure (that I use):
-Draw air into syringe
-Put syringe into vial
-invert vial
-draw the oil. Don't worry about the air
-with vial still inverted, remove the syringe
-I draw back the plunger a bit to make certain all of the oil if out of the pin area.
-remove the pin with the syringe still pointing up
-attach a smaller pin with the syringe still pointing up
-push the air out of the syringe with the syringe still pointing up. Let a drop of oil trickle out of the pin for lubrication. If there are bubbles, flick the syringe a few times. A couple of very small bubbles isn't a problem.
-Do the injection procedure.
