Mixing by Weight - Are You ??

[Gfinch]

You also have to take into consideration the weight of the bottle you will be using when you tare it to zero the scale for mixing. The weight of the bottle is included in the maximum scale capacity even if you have tared it and it reads zero. See my post for a good deal on a 600 gram balance. They still had some in stock a few days ago, it is an older model that is being discontinued I believe even tho that is not what they say in the description. The scale was introduced in 2008 or 2009.

I have not gotten home yet to try the scale out yet, still on the road, but. I was informed it arrived in a large box, carefully packed as a precision instrument should be.

Ya know, right after I hit Post Quick Reply, it hit me that, after you experiment to get the flavor right (in a small size) and you've calculated the percentages by weight for PG/VG, nic, and flavorings, you could weigh all these separately then mix after, so even with a 300g max scale, you could make batches by the gallon. It's just up to how many times you want to weigh the < 300g parts. Right?

You are absolutely right...If you start the scale with the weight on it already it will always register 0, and if you keep taring the parts you can make as much as you want.

So break out the old gallon of milk container and start mixing

I believe you misunderstood Devil's post.

The max is 300g. It cannot be exceeded, no matter how many times you attempt to tare/zero. The balance can only weigh up to 300g at one time. Then you must remove some or all of whatever is on the platen, in order to weigh any more. If you remove everything on the platen, you can then weigh up to 300g more. If you remove only 100g, you can then weigh up to 100g more.

If your empty bottle weighs 100g, then you can only put 200g of liquid in it. The max of 300g can not be circumvented. That's why they make/sell 400, 500, 600, 1000g etc. balances.

Yea. I found that out the hard way with my 200g scale. The weight of the bottle counts even if you zero out the scale. I like mixing in 120ml glass bottles. Needless to say, I have a 350g scale on the way.

Wonder if you could just mix the flavorings on the scale and use graduated cylinders or beakers for the other things. I realize this is not "going all the way" with the scale, but it would let you mix larger batches with the limits of the scale.

 

[Gfinch]

Also keep in mind on these scales if you place too much weight on them you can permanently damage the scale. That is unless you spent enough money to get one with built in protection against such mishaps.

I have a 100 g scale one of the cheap ones....

I can put a 200 g calibration weight on it, it will read " 0-err"
If I put the same weight on it with the scale off and turn it on it will read "0" and it will calculate from there up to 100 g without the error message. If I remove that weight it will read "0-err" again because it subtracts the weight and goes below -100 the max of the scale.

That was why I said you can mix as much as you want if you don't exceed the scale limit on a single part. I guess all scales don't work the way mine does then, I just assumed it did.

Here's the one I have:

This is fascinating to me.

My first question (in post #120) was about how big can you go and I realized BIG (in #122) even with a 300g scale, bigger than I'll ever need.

But now I'm wondering how small can you go? I don't know what a "drop" weighs.

So assuming everything, just spitballing the numbers, if 1 ml=20 "drops," (I read somewhere that 20 drops of water is 1 ml.) And if I just assume that's true, whatever a drop is... that would make .05ml=1 drop.

I found this coconut oil conversion thing at Coconut oil amounts converter | Nutrition facts | Convert to units and culinary measures.

In step 1 on this page if you plug in .05 to 4 decimal places with Step 2 at ml and Step 3 at grams, it shows that .05ml (1 drop) of coconut oil = .0457g so...

with a scale with +/- .01 grams accuracy, you should be able to measure a "drop" of eliquid ingredients.

So weighers - Is that true? Does 1 drop show a change in weight on the scale? Seems like it should.

But now I'm wondering something else. If you measured out a 10ml batch and got it just right.... in real world experience, does the 10ml batch taste the same at a large size like 200ml? In theory it should but does it in practice?

I hope someone will answer these 2 questions. But if not, I will, because I'm going to buy a scale and try this out.

Yes 0.01 scales do change with every drop so you could measure it out..that's the reason for the 0.01 scales. The second question is yes in practice they will taste the same. That's the other reason why we all make small batches to learn the right percentages before we waste supplies on something that doesn't taste right. One thing to remember is that we all use e-juice calculators to measure the weight. The weight of one drop will always be dictated by the equipment used to produce that drop, if you use the same dropper you will get the same type of drop most times. Using the scale instead of eyeballing with syringes helps us to make more consistent batches mix to mix. No matter what the volume of the ingredient added, as long as you use the same quantity you will have the same mix.

The scale you bought will do you just fine, should help you become a mixing by weight master in no time. a 500g scale will let you mix a little over a pound of liquid .

Thanks for the confirmation. Mixing by weight seems to be easy, accurate and consistent with virtually no cleanup.

I got the juice calculator at http://www.e-cigarette-forum.com/forum/diy-e-liquid/480587-new-calculator-try.html that uses grams though I haven't really looked at it yet. And with 56 pages (so far) of comments in that thread, it will take some time to go through.

First glance, it seems far superier (to ejuicemeup for example) because it has some inventory and cost functions and a lot more stuff just by looking at the drop down menus.

Anyone pushing for a Mixing by Weight subforum under DIY E-Liquid? It'd be nice to have all this in one place.

Nice. With free shipping even! 500g, and you can even plug it into a USB!

Yeah, I went with the 500g because I may have other (weightier) uses for it with the counting function. And they had a $23.99 version that only took batteries so I figured I'd splurge and get the one that takes batteries and usb for a dollar more. I was never a boy scount but I like their motto.

My drops typically weigh 0.03 grams from glass dropper tops. Those cheap pipettes may be weigh out closer to 0.02 grams per drop.

Getting a sub forum for mixing by weight would be awesome. However I've noticed resistance from other members regarding the mixing by weight thing. Typical of people who are set in their ways and refuse to embrace new and easier ways of doing things. That's fine. As time goes on, younger and open minded vapers will see the benefits of mixing by weight.

Just this morning, I whipped up 270ml of juice using this little 200 gram scale. Super easy, very fast.

Give some of old f@rts some time and we most likely will start to embrace mixing by weight. To me it is probably the most repeatable method given the "tools" we use to measure. If I was in a quant lab, I may differ, but that's dreaming...lol I've been checking out the scales and looking over the proggie that lets you measure in grams. Shouldn't be too much of a hassle getting set up and once done, it's a breeze.

Will you please tell me how you make your labels?

Handmade or Avery stock?

Label program on PC?

 

[mxrdrver]

I use Avery 8160 Labels I picked up at my local Staples. Then I downloaded a blank page from the Avery website and saved it in my OpenOffice word processing program. OpenOffice is a freeware program that works like Microsoft Office.

So you can print partial sheets of labels without wasting the remaining blanks on the sheet? That was a big bugaboo with what I used to use for printing. Lots of wasted labels -- ended up hand labeling them.

 

[mxrdrver]

Yes U can print 1, 2 or as many labels U want. Each "slot" can be customized for a different mix. Then save the sheet for next time.
