I have a question that hasn't been answered by looking or searching (search term skills are not the best) the threads. I understand when formulating a new ejuice recipe that it is best if only a 3-5ml test sample is developed. There is little or no ejuice wasted. My question is with the tasting. I have two Russian 91s (original developer), one Kayfun clone by Tobeco, two Kanger tanks (I&II), and some sort of clearomizer for an Ego. I hate to think that I must tear down any tank or clearomizer, clean/dry burn, and replace/wash the wick to ensure the tested sample is "pristine" without cross contamination. This would seem to become trying when 5-10 test samples of small formulation variation and/or steep times are under development.
So my question for the DIYer; what would be recommended for sample testing?
