Syringe issues

[JCBourne]

I'm wondering if anyone has had this issue before.

Drew up the last 1mL of oil out of the vial, then pushed the air between the oil and top of the syringe to draw more oil out of another vial. However I could not pull back on the syringe, nor could I push down, it was literally stuck. The only way it would move is if the needle was pulled off. At this point I decided it wasn't safe to use anymore so I put back on the needle and same issue.

Anyone else have this happen? I lost about 1.25mL of test

Also, how many of you inject the air into the vial before drawing? I sometimes do, but I had a vial explode once (was awhile ago I don't remember how) but it was along the lines of either injecting air and/or oil back into the vial. What's up with that? I'm afraid to inject 2-3mL or more of air into a vial because I think it's going to blow up.

The vials should be sealed and in vacuum status. you only inject the same amount of air that you intend to draw out of product. you need 4ius, inject 4ius of air before pulling the 4ius of product out. you want to maintain as much of a constant vacuum in the vial as possible at all times to prevent the growth of any bacteria and or microorganisms. it you are bursting your glass vial you have WAY too much air in there. put a dry pin in there and pull out as much air as you can or until the plunger starts to fight with you and that should be a sufficient vacuum.

Maybe there was a foreign body that got stuck in the pin. It sounds like it was clogged up.

That is why I always buy separate needles and use a fresh needle after drawing.

Maybe u sucked up a piece of the rubber stopper since it was the end of the vial and it clogged the needle.

Yeah it was strange. Never had that happen before.

It was a smart move to toss it.
