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.
heat up the oil so it flows throw the needle easer.

do you have to inject air?
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.Quote:

21g is big man! I would use atleast 23....If not 25g.
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.
i like BD 21 because it goes in easyier plus i have 23gs and they bend and go in too slow and stufQuote:

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.
one to two seconds lol :2jk:Quote:

hey thats not a bad idea smitty
took me about 13 seconds
wasnt too bad
but im gonna go alot slower next time
and i cant tell the difference with injecting with the same needle or a new needle..even while using a 21 guage
