Maybe it would be a good idea to add some O rings to bottles after filling them? I know it's not just me who's had an issue with spillage. I've never lost more than 1/4th (other than an entire sample once). Seems like a pretty inexpensive way to prevent the spillage that seems to happen a lot, and they should be less than a few cents each.

On an unrelated note, how many ml are the sample bottles, around 2ml?
