New weight mixer question

[bwh79]

weights of liquids will vary depending on altitude, temperature, and a host of other factors.

Actually, that's a very good reason why you should measure by weight, instead of by volume. If you take the same "amount" (mass/weight) of something, say ten grams, and measure its liquid volume at sea level, and then again at the top of Mt Everest, you will get two different readings because the density changes and it becomes less dense (i.e. larger, will take up more volume) at the higher altitude. So your ten grams of liquid might be 9.9ml at sea level and 10.1ml at the top of the mountain. Which one is "correct"? That depends on where you were when you first wrote down the recipe.

On the other hand, if you measure it by weight, and you measure it on Earth (or on a spaceship accelerating at 1G, or anywhere else with a gravitational constant equal to that here on Earth), then that ten grams will always be ten grams, no matter what. Which one is "correct" this time? It doesn't matter where you took the initial reading this time, because they're the same.

I don't understand why you want to DIY by weight when just about the whole vape world mixes by percentages. Why spend the money on a scale when a few syringes are dirt cheap. Good luck with your quest if you are that determined.

I use a Scale because there is Less to wash when I am done.

Hi all,

I'm new to diy mixing by weight and have couple questions:

Q1: I would like to buy a American Weigh Scales LB-501, but it is currently OOS at Amazon. Which of following scale would you recommend? I will only mix juices with 30ml or 60 ml bottles just to try out some recipes. ( the DIY e-liquid here is very helpful & amazing!!)

A. American Weigh Scales ACP-200 Digital Pocket Scale, 200 by 0.01 G
Amazon.com: American Weigh Scales ACP-200 Digital Pocket Scale, 200 by 0.01 G: Digital Kitchen Scales: Kitchen & Dining

B. American Weight 100g x 0.01g Digital Scale
Amazon.com: American Weigh 100g x 0.01g Digital Scale: Educational And Hobby Weighing Scales: Kitchen & Dining

Q2: Does American Weight 100g scale good enough to mix a 60ml bottle?

Thanks all!

I would suggest getting a Scale with a Little more Capacity that 100g.

200g would be the Lowest I would suggest. Because you have to Not Only consider the weight of the e-liquid, but also the Weight of the Bottle.

 

[zoiDman]

Know your weights

PG = 1.038g
VG = 1.26g
100mg nic in PG = 1.035g
Flavor = 1g

With flavors I always use a value if 1g in all my recipes that way they will always turn out exactly right no matter how big of a batch thats made. Make sure you make these adjustments in your calculator. I use pg nic base. I can not tell you how much VG nic base weighs. Accurate every time

Or you could just use 1.000g for Everything. And adjust you Recipe accordingly.

Bottom line: if a recipe calls for ten grams and you use ten grams, then you always have the right amount. But if the recipe calls for 10ml and you use 10ml, it can matter where you are. To make sure you have the right amount, you have to be in the same place (or in another place, with similar conditions) as they were when they wrote it down the first time.

However, we are more concerned with "repeatability" than dead accuracy. It does not matter if your measurement is perhaps off by a few percent, so long as it tastes just as good this time as it did the last time. With that in mind, a .01g scale can measure to within a tolerance of less than a single drop. Can you get "to the drop" accuracy/repeatability out of your syringes? Not to mention the convenience factor, in terms of time saved and ease of clean-up.

I see your logic... but explain this to me. In the course of humanity, with all of our leaps and bounds as we furthered our intellect and learned from our mistakes why is it that it is still generally acceptable across the entire world that liquids are measured by volume and solids are measured by weight? If measuring liquids by weight is so clearly the superior method of measurement, then I'm sure it would have been adopted as the proper means. I'll stick with the tried and true...

It's actually quite common to measure solids by volume. Have you ever baked cookies and used 2 and a half cups of flour? Did you bust out the scale and weight that flour, or did you use dry volume measuring cups, like these:

Plenty of liquids are measured by weight, also. Go look in your fridge or pantry, and find just about anything that isn't a beverage, and I'll bet you the amount on the package is given in net weight instead of volume. This is because the volume of something can change depending on many factors, but, as long as we remain here on Earth (or anywhere else with a gravitational constant of 1G), then weight and mass remain irrevocably tied to each other, and that (mass) is the true measure of how "much" of something is there. The bottom line, as I said above, is that ten grams will always be ten grams, but ten milliliters of something can change in volume depending on where you take it.

I can see that you do Not have much Experience in either Commercial or Industrial food preparation. But hey, that's Cool.

Everyone should use the Technique that they are Most Comfortable with. That is Really all that Matters.

I can see benefits of measuring by weight, and do agree that you can get consistent results by doing so. I just have a differing opinion and prefer to measure by volume. I use the same graduated cylinders every time, I buy syringes in bulk and use the same brand (though I'm looking for a nice set of glass syringes to re-use indefinitely). Bottom line is? I'm happy with my results, you're happy with your results, and there is no harm in sharing both sides of the opinion so that Alex can make his own decision as well.

What will happen if you happen to drop and break one of those cylinders/beakers and have to order another? Or maybe the place you buy your syringes goes out of business and you have to order from another supplier? I'm just curious.

What happens if scale goes bad? I'm just curious.

Good ... if someone dislikes my liquids-mixed by weights, I can now blame it on missing out on half an angstrom or miscounting these molecules

 

[Kevin Foster]

I think this topic has got a bit out of hand, x likes mixing by weight, y likes mixing by volume. As long as you are happy doing it whichever way you prefer then that's all that matters.
