OK, I switched over to PVLabs enth (three shots ago)... It's pretty thick stuff.

I'm drawing through a 23 g (easier to buy one box) but I'm having a bit of trouble. I'm patient and all that, but I've noticed it contains so many air bubbles... I couldn't figure it out as Mrs. B's eq never has a single bubble...

Anyway, to the point, I was watching it real close this morning and it appears that it's drawing air (BD set) through where the pin attaches to the syringe. Tiny, tiny bubbles. I tightened it on pretty good, but I always switch pins to shoot so I didn't really torque it on there. Definitely gave it a good twist though, enough that I had to apply some good pressure to remove it.

I know some obvious suggestions are:
- warm it with hot water (I'll try this next time).
- bigger g pin for drawing (tried an 18 g once but it left such a gaping hole in the rubber stopper that I decided to preload everything from that vial -- would a 21 g make enough difference maybe?)

I run the syringe under warm water and it helps get the bubbles out quickly, but I was thinking today that drawing air CAN'T be a good thing... almost even worried now (although I'd know by now if something was wrong). It's increasing my risk of infection I would think.

Anyone else have this problem?
