What about using glass syringes to transfer the reagent?It works well enough, I suppose. Definitely cheaper. But it was messy transferring the reagent to an amp, and the stuff ate the rubber in the syringe which ruined the reagent after a few minutes. No matter how careful I was I always ended up with sticky fingers. I'm pretty sure I could have developed a decent list of colors for comparison, not as good as labmax, but good enough. I just didn't like all the fuss.
