Hello everyone at DIY_eJuice, I am currently working on a powerful new e-juice calculator and I would just like to get a general idea of how everybody here measures their juice.
Please post your personal mixing method in the comments. Thank you so much for your input! It means a lot to me.
I am pretty happy with the stability and usablity of the current build so if anyone would like to check it out please feel free to download it. I have included 330+ TFA and Capella flavors to use
Direct Download - Vapor Lab 0.8.1.4 BETA - Windows
EDIT: Wow, thank you everybody! I was not expecting such a great response! It is clear to me that the best solution is to not limit the user by their tools and I will support drops, mls, grams, and metricshitloads. The grams measurement in the beta linked above does not take into account the weight of the flavor molecules, it is calculated only based on the PG/VG the flavors are suspended in. This is fine for small recipes but the discrepancy becomes pretty noticeable in 100ml+ recipes. I will be adding support for specific gravity of flavor molecules taken from the MSDS available.
If anyone does want to continue to use the beta that is fine, I will add support to patch your database (and preloaded items) to support the upcoming versions.
grams, its just so fast an easy.
Agreed. A bit time consuming up front to get the weight for every ingredient, but it's just one time work for the most part, and a lot of it can be pulled directly from the specific gravity off the MSDS sheets (which most reputable flavor producers provide).
Much easier to be accurate and repeatable when using weight, IMO.
Wait so you're saying using the density of pg isn't sufficient? Aren't most flavors >80% pg by volume
Not technically. And there are many flavors don't use PG as a base. There are a few flavors I use very frequently that are concentrated in an alcohol base, not PG.
As far as being sufficient, that just depends on how precise and repeatable you want to be. I use weight to be very precise and repeatable, so I didn't see any point with using weight and then not doing it properly. It's not the end of the world if you do that (estimate using the density of PG), as long as you do it consistently.
But in the real world (manufacturing, etc..), you wouldn't estimate like that (and in some cases businesses would be shut down and fined for doing so).
Mostly by ml, but if we get down into adding, say, .25 ml of a flavor or nic i don't mind going by drops.
Me too. Mostly because it's easier to write down the recipe in ml and most of the time recipes that are shared are in ml. Besides, I have a little over two years worth of recipe notes that are in ml.
I rarely do drops. I do have some flavors that MUST be drops like tobacco absolute, coconut extra, coffee stuff, etc.
I might try using weights, but it's a lot of work, time and money getting started.
mls and drops, I prefer accuracy over convince...
im measure my ml's
drop's is not accurate, and don't have equip for weight
Thank you, I completely agree about drops being inaccurate. I am considering not even including the option of using drops in the calculator
Converting to drops is completely useless in a calculator because every dropper is different so it won't be the same for everyone. Different densities also make this very inacurate.
To mix for yourself though, I think drops are consistent enough if you always use the same dropper. They're probably more consistent than syringes, there's always some liquid that remains in those, but a drop's a drop.
Edit: I knew this was going to be downvoted. It's still true, just goes against popular beliefs of this sub.
Syringes are much more accurate if used correctly. The key is not to have any air in the syringe, it should be completely full from the plunger to the tip. The liquid in the tip is there before and after injecting, so it is not changing the amount that was actually injected.
You can usually prevent air in the syringe by drawing up the liquid, injecting it back into the bottle with a bit of force, and drawing it up again. As long as you use the right amount of force, it will push the air bubble out ahead of the liquid, leaving the tip still full. Then draw it up again and there should be no bubbles.
Edit: to use your terms, a drop is different between every liquid and every dropper, but a ml is a ml. :)
The liquid that remains in the syringe (needle mostly) is not part of the measurement. If you draw up to then 4 ml line then push the plunger all the way down, you have 4 ml, if you draw up the plunger and squirt out whats left in the needle too, you have more than 4 ml.
I only use a 20ga needle for drops. I don't know how many drops of PG per ml come out of it and I don't care. I only use drops for a select few flavors like coconut extra, coffee stuff, tobacco absolute, M-Type, etc
If it weren't for those flavors, I wouldn't need to bother with drops, but when I do I make them as consistent as possible.
grams or msl
I'm having trouble finding the exact value of a msl, but I will add it to the features list!
