Small mix batch on a 500 g scale

Small mix batch on a 500 g scale.

Want to mix individual 2 ml batches with 6 or more flavors by weight on a 500 g (.01) scale.

Have you tried this and is your results repeatable and done satisfactorily?

Any problems?

2mls is a little small 1drop at that small a ratio can be too much. A single flavor no problem. It would be doable if you mixed the flavors first. 1% is .02 a drop often weighs more. Best way would be to try it. 5ml batches are pretty easy

I'm guessing here but it might be fair to say:
From reply, 500 g (.01) should yield same results as a comparable 200 or 300g (.01) scale.
2 mil total mix batch can be tricky with syringe or scale method (limitations on % and no. of flavors).

Many thanks to sketchness for information.
Any other replies are welcome.

The 500g you mention is just the maximum capacity of the scale and has nothing to do with accuracy and resolution. Assuming all 3 scales (500g, 300g and 200g) are having the same accuracy then the results will be exactly the same.
2ml is too small an amount to mix using so many flavours. Not because of the scale but because it's impossible to add such tiny amounts using a syringe.

impossible to add such tiny amounts using a syringe.

I agree, it is impossible to accurately measure such tiny amounts with either syringe or by weight methods for 2 ml batches. For 2 ml batches, I have found that I can get "fairly close" using a syringe if the number of and the amount of flavor I'm using is somewhat significant. The needle drops are somewhat controllable with a syringe. A syringe would have to be used in both methods of measuring to get "fairly close".
"fairly close" allows me to get a feel for the larger 5-up ml. mixes if I want to seriously explore the possibilities of the flavor mix.
In short, may I concluded:
Mixing by weight and using whatever in conjunction can be just as accurate as mixing with a syringe method only for small 2 ml batches with a limited number of flavors (all things being equal between syringe and weight measurement).
Other probable conclusions:
Since 2 ml batches are so small neither method of dispensing precludes the other.
.01 scale readability is fine for batches exceeding 2 ml but a scale possessing .001 would be more accurate and provide better repeatability.

How is that going to matter when a single drop weighs in at .02-.04g? You gonna cut it up with a razor blade and add 1/20th of a drop to your mix or smth?
