I've heard this often. Anything thicker than a 23g has the possibility of releasing small chunks of black rubber butyl into your vial..You can use a smaller pin to draw it up or just avoid any chunks you cause. They will sink because they're heavier than the oil. Our rubber stoppers aren't old and they're as rubbery as they should be and if you keep stabbing them with a 21g, some rubber is bound to chunk off.
Discreet, call around to pharmacies in your area to see if they have them.
It is standard practice in medical facilities whenever glass ampules are utilized, to draw the solution with a filter needle to filter out shards of glass from the breaking of the ampule.

These look great. Am I correct in understanding that these are needles with built in filters? So basically the way they work is by filtering the oil before it reaches the barrel?
Do you happen to know which syringes they match with?
I'd like to be able to use these, then swap over to a 25 gauge for injection.

Yes, that is correct. There is a filter built into the hub of the needle itself, so the compound is filtered before it reaches the barrel of the syringe.
They should fit any luer lock syringes (the kind with the screw on/off needles).
