I use pipettes, drawing the CA up from the bottles as several of you do. However, I use a pair of long-nosed pliers to stretch the thin length until it begins a new length of VERY thin tubing at the end. This is easy. If you haven't tried this, just pull fairly hard and it works without any real finess needed. I keep all my CA in the refrigerator door. While I have the same problem of threads getting filled in the caps, it takes longer to occur, and the pipette bulbs with CA last longer. If they close, I just snip off the end of the long-ish thin section, and it's open again. The tiny diameter works fine for thin CA, allowing more accurate work, using less CA for a given job.
Yesterday, for my first time ever, I had to throw out two partially used bottles. They were years old though.
