Filter Needles and Ampules
I was told by a close friend who is also a Pharmacist that when using ampules you MUST use a filter needle when you are drawing the gear into the syringe because glass particles will fall into the ampule. If you get these glass fragments in your body it could kill you. Any feed back
You may have just answered my question....

I bought a .45 syringe filter, hooked up a pin and tried to suck up the sterile water that was in an ampule I just made a mash out of trying to open. I couldn't get so much as a drop to come up thru.
So, if I am making the correct inference from what you said BWitaker, the proper thing to do is suck the tainted stuff into the syringe first, then hook up the filter (and presumably, a new pin?) and filter it on it's way into you?
