When I mix by weight can I just use the exact values given by eliquidrecipes.com calculator when I make the recpe? Or, does it need to be more accurate? The weights of the liquids per ml go out to like the ten-thousandths I think. But the calculator only goes out to hundreths. Is this close enough? Or would I really need to have that extra bit of accuracy to make a noticible difference?
I usually shoot for plus or minus .02 grams for each ingredient when mixing a 30ml bottle. I wouldn't worry about thousandths of a gram.
ok cool that makes it so convenient for me so i can just put my recipe on there and not have to calculate. ( jus been mixing by volume so far)
True. Check out www.alltheflavors.com too. Great calc, great mobile app made by a local bot hating genius: /u/queuetue . That app also lets you weigh flavors as pg which is (I believe) 1.036g/ml vs water which is 1g/ml. Don't ever bother trying to measure individual flavor weights unless you plan to mix hundreds of gallons of organic all vg for astronauts. You'll go crazy. This is a fun hobby/money saver.
Edit: 1.036
Thanks, elephant.
Both the web and android versions of atf use:
> PG_WEIGHT = 1.036; > > VG_WEIGHT = 1.26125;
It should be mentioned that not only should you use 1ml=1g for flavors because it's simpler, but also because most other recipes you encounter will be calibrated in the same way.
In most cases, more "accuracy" here will result in less fidelity and less compatibility if you want to share recipes later.
I find one drop out of those tiny plastic drip tops that come on small flavor bottles tends to be around .02 grams so that's the best resolution you're probably going to get. Still much more accurate than volume measurements (unless using very expensive laboratory pipettes)
Form a small bubble on the tip and tap it to the inside of the neck on the bottle. You can creep up to get it to read the exact amount you want.
Lab pippettes are accurate but they take forever with pg and vg to let it fully drain.
I do that to get that last hundredth, cause I know a while drop is going to go over and it messes up my while recipe if go over. Ocd sucks
Think of it this way. If let's say 1 drop is .033 grams (30 drops per ml and 1mg/ml). Now let's say you have a 30ml recipe that calls for 1% of a flavor. That is .3ml or .3 grams. A 1 drop difference is a little over 10% error. For every .01g you are off that is a littler over 3%. Now let's say you use .5%. 1 drop off is about 20% off. For higher percentages and larger batches it isn't as big of a deal, but small complex test batches can have a wildly different taste each time because of this.
So what you call ocd, I call making a consistent juice lol.
i havent encountered those yet ordering from wizard labs i was jus planning on using cheap pipettes i guess. but thats good to know yea idk why i ever decided mixing by volume was a good idea. guess it jus looked easier but i recently took another look at mixing by weight and its not only easier and cleaner. but also i can see how much more accurate it is because it does remove alot of human error
Even a 1ml syringe can be +/- 0.1ml given the amount of liquid in the needle.
Measuring by weight, you'll never be off by more than 0.02ml.
Weight is infinitely more accurate.
When I was using syringes that always bothered me. If you were using a 1ml syringe and needed to put in a low amount like .1 I'm sure it was doing up to double that because of the flavor in the needle. Never really tested it but it would be interesting to know how much gets caught in there.
