A journey down the rabbit hole of mixing e-liquid.šŸ°

I will see what I can find on eBay thatā€™s a good deal, thing is I buy them broken and fix them, usually just need cleaned and oiled.

I ended up gettin* this one

So far Iā€™m happy with it.

This is a good price with shipping, maybe @mrpipes can chime in.

Yeah that looks decent. Iā€™m not familiar with that particular model but its certain that it is USA made. A lot of the Asian stuff use computer fan motors that donā€™t compare to these old ones. I would offer him $20 and bet that he would take it. The old ones are far better quality and can be had at great pricesā€¦

I just watched ā€œChef vs Scienceā€ recently on Netflix, and (I could be wrong, but I think the scientist on there said the opposite) they made a tomato soup in a seriously unorthodox way.

Itā€™s been a couple weeks since I saw it, and Iā€™m not even 70% sure that he froze it with LNā€¦ Though I know that was used too at one point. I do recall he ran the tomatoes through a centrifuge too though, to separate the solids from the liquid tomato essence.

(Apologies if I remembered wrong, and this is a derail. But never in a million years could I have guessed Iā€™d be discussing that show later, much less in such a short time frame. :laughing: )

I completely agree with you, and Iā€™m extremely tempted to move it myselfā€¦for the time being, Iā€™ll defer to someone else to handle that though. :wink:

He used the LN to make the steak. I watched it about a month ago, what he did with the tomatoes was a lot of work.

I agree. Iā€™ve had a lot of concerns about this being under beginners when the subject is anything but that. I donā€™t want any beginner to get the impression that they need a multi thousand dollar piece of equipment to make good ejuice. However, I do think they need to understand the underlying principles. I plan to post separately, but am going to make sure that I present it all correctly. I need time and am doing control testing.

Is there an ā€œadvancedā€ mixing area? Can we make one?

Itā€™s just an idea, more so to let people know they donā€™t need a whole lot of gadgets to make good juice, but some of them save time and ease the process.

Thatā€™s a great question for @daath I do believe! :wink:

Perhaps ā€œAdvanced Tips and Techniquesā€?
(just an off the cuff idea nameā€¦ Whatever you think boss!)

Technically if your thinking about buying your first homogenizer this would be a good beginner thread to read.

I would contend that:

Then youā€™re way beyond basic mixing principles.

(And have at least a fair modicum of experience under your belt.)

You donā€™t hand someone out of driverā€™s ed the keys to a Bugatti Veyron.

my brand is from a company called everything liquid I get my VG, PG AND Nicotine from them.

Maybe this is the solution to my problem ā€¦
I have noticed that when I open a bottle of 50mls juice, when I get to the middle, the juice does not have the same initial taste. Which led me to buy a magnetic stirrer (without heating) ā€¦ even so, I still have no improvement in the result.
I think the problem is in the homogenization of the liquid ā€¦
Will buying a 70VG / 30PG base improve the juices instead of PG and VG separate?

Edit: And yes, I always shake my juice before filling my RTA!

I wouldnā€™t say that. I do remember looking at homogenizers and mag mixers back when I started. From lab supply stores $$$ kinda turned me away at the timeā€¦ until I can either save up for them or find them cheaper those ideas were placed on the back burnerā€¦almost 1 yr later I bought a cheap heated mag mixer for Christmasā€¦ probably will get one with a temp probe later or if an insurance job comes thru I may get a homogenizer

So Iā€™d based of my experience depending on your financial situation the DIY starts with different mixing tools

The James Bond Method (shaken not stirred)

Egg beater

Mag mixer

Various kitchen blender

Paint can shaker

Homogenizer

Etcā€¦

He used a centrifuge to make the tomato soup. Reminds me of work! :joy:

I donā€™t think so and have a pretty complex answer why I think that. It goes to your other statements ā€œthe juice does not have the same initial taste. Which led me to buy a magnetic stirrer (without heating) ā€¦ even so, I still have no improvement in the result.ā€ And ā€œI think the problem is in the homogenization of the liquid ā€¦ā€

The definition of ā€œhomogenizeā€ shouldnā€™t need repeating but associated terminology can complicate matters. One is to emulsify and others are volatility and dispersal, and with a homogenizer, shearing the molecules in the mixture to uniform size.

To emulsify is to combine immiscible (substances which donā€™t readily mix) substances. Oil and water is the perfect example. Ordinary stirring will not create an emulsion. It will separate almost instantly. Thus, the need to shear and force these substances together. But in making ejuice we are combining volatiles which are our flavoring themselves: Volatility denotes rapid evaporation, that is evaporating rapidly in the form of a vapor. The volatiles are what we taste and smell which in essence is the same thing. Solvents such as alcohol as well as ā€œharsh notesā€ have to evaporate in the mixing process.

How miscible (mixable) or immiscible our chemicals are is beyond any means I have to determine. But clearly there are varying degrees involved in the perhaps hundreds of chemicals we are using even though they are (or should be) all water soluble. Thus the sometimes very long ā€œsteepā€ and others that mix near instantly. So I set out to learn how to control the above factors.

There are several things that led me to begin homogenizing my VG/Pg or VG/Water/ Saline base separately. One was a method developed by @ Maureenie and another was from a maker of lab equipment which demonstrates that VG will not homogenize at below 60 C ( 140 F). So even if I hadnā€™t noticed a difference in weight in VG products I would have continued using this method. Heat VG or VG/PG by itself and use whatever mixing device you choose to use. I never heat Nicotine. I use some heat with many flavorings added later but keep the temps generally below 120 F. The more heat, the more off gassing of the volatiles.

I also avoid aerating any mix that has flavoring or nicotine. Oxidation will degrade both. In the design of all homogenizing equipment, all eliminate the introduction of air. The small lab units will allow small amounts. The in-line sealed units eliminate it entirely.

I hope I have answered your questions and sorry for the length.

@mrpipes well put buddy, youā€™re a lot better at explaining things than myself.I wish I was this good.

Thank you mrpipes for your comment;)
I already wondered if it would not be a problem with the volatility of the aromas, because when I open the bottle, the flavor is there, that is after 15 days, or 1 month. then I start to vaporize and Iā€™m losing some notes, as if the juice loses its freshness ā€¦ bref. the solution in the immediate, passes by making lots of 30 mls. and so I am entertaining myself to cook more often ā€¦ lol
