I rinse out my old reagent bottles from my pool test kits. They come in a couple different sizes. I keep a small one in my pack, and the larger ones I keep in the side panel of my truck and one for the work bench. It's nice because the tips are "drop-wise," except for the cyanuric acid is more of a stream. They come in handy for my nail guns, too. I also fill one with old damper fluid for drilling lube.
