Okay - now for my stupid question ......
When filling testing vials, do you fill to the bottom of the curve of the water? In other words, should the bottom curve line up with the fill marking? Or other????

The lines on them are notoriously wrong. I think as long as you are consistent you are fine. I ended up ordering a cheaper 10ml pipette off Amazon and use that. That way I'm consistent test to test.
