    drawing from a vial

    i found it really difficult to draw from the vial..sust 250 with a 21 guage needle
    i follow directions found on the net

    i wanted to inject 1 ml(sust), so i followed directions, put needle in vile, injected 1 ml of air and tryed to draw, instead i kept drawing more air and could BARELY get any oil out...and everytime i did i would get these huge bubbles

    is the directions i was given totally wrong
    any tips?

    its not me who i am injecting...so please dont btoher asking for stats, etc

    Make sure the needle is tight on the syringe before you start, they are almost always loose out of the package. The first thing I do as I unwrap the syringe is snug up the needle.

    Yes.
    it hurts less if you draw with one pin and change it to inject....people think it is more sterile but it is,nt..... my doctor/nurse draws and pins with the same pin all the time.....an also you cant change a diabetic needle....

    injecting air helps as it creates a negative pressure vacuum, meaning it puts pressure in the vial which helps push the oil into the syringe, heating it is a good idea

    if it's a vial, you should inject air equal to the volume of compound you wish to withdraw.

    After you insert, blow in air, when drawing back, draw slow to help allow it to be drawn into the needle.

    Switching pins after drawing is a person preference. I personally changeto get a nice sharp needle when injecting.

    much smoother this time..i went slower
    and injecting with a 21 guage seems to be no problem... not even any blood after the needle comes out
    THANKS YOU GUYS R GREAT!!

    once you jab the top a couple times it regulates itself, glad things went better this time

    i've timed mine several times, oil based test p for instance takes roughly about 20 seconds for 1 ml with a 23 gauge. i dont think thats long at all..... how long does it take for you with a 21?

    nother technique is not to hold the needle at an angle when drawing from the vial. Sometimes the rubber will not seat well against the metal and wont draw out as good.

    What ive found to be the easiest way to draw from a vial is stick in another needle (only) whilst you are drawing. This alleviates the pressure.
