To mix and store my stop, fix, and HCA, I use 1-liter plastic Datatainer bottles. They're rather inexpensive. I label the bottles AND the caps so I don't accidentally grab the wrong chemical.

Another neat thing for measuring out very small quantities of HC-110 or Rodinal is a baby's medicine spoon. They look like plastic test tubes, with spoonlike ends, and can be found easily in drug stores. They hold about 10mL and are super easy to read with precision.
