I recently bought some eGo Cartomizers and have to say that they work Great.
Except There is not a Good Way to tell How Much juice is in the Carto. I have refilled enough Regular cartos to visually see about how full the carto is by just looking down into them. But that is not Possible with the new eGo Cartomizers. What a cruel twist of fate this is. A great Carto with a Hidden Flaw!
So I mulled it over for a couple of days. Couldnt think of a simple way. Why cant I think when it is Hot Outside?
It came to me last night in a Dream. I woke at 3:47am from an altered state and Bolted straight up out of Bed. I had it. I made a bee line to the garage for my Reloading supplies.
One of the key pieces of equipment needed to Reload ammunition is a good scale. You use it to Calibrate the powered charger to dispense accurate amounts of smokeless powder. After some searching and getting my bathrobe caught in the drawers of a roll-away, I found it.
I took a blank eGo Cartomizer and measured it. It came out to 4.07 grams. I then zeroed the scale and put 2ml of Tastyfinger into the Cartomizer using the ZDB method. Then I re-measured the filled Cartomizer.
It measured 6.29 grams. Why is it that at 4:10 in the mourning you cant find a calculator? With a dull pencil and a cocktail napkin I calculated that I had just put 2.22 grams of e-juice into my Cartomizer! This made sense. Vaguely, I remember from an Organic Chemistry class, that 1ml or water weighs 1 gram. So 2ml of water would way 2 grams.
Adjusting for drift and not considering features like specific density, Non Sea Level Gravitational Forces or the concept of the Mole, I round off my observed values to 1ml 1 gram for Tastyfinger e-juice.
So now I had a baseline of what an Empty Cartomizer weighs, rounded up, say 4.1 grams. And what 2ml of juice should weigh, about 2 grams. Thus a full eGo Cartomizer should weigh about 6.1 grams.
It wasnt that far off from the observed. At least close enough for Government work or the Home Carto Refiller. But what good is measuring Blank or Filled Cartos? Not Much, but here is where the marriage of Physical Science and Vaping comes in.
I took a Carto that I guesstimated to be about ½ full and weighed it. It weighed 5.0 grams on the money. So using the dull pencil I figured that a Carto that weighed 5.0 grams should be able to take 1.1ml of juice to top it off. A near Empty Cinna-Bomb Carto weighed 4.3 grams. Cool, it should take 1.8ml of that Magic juice that makes your eyes water. I now had a way to tell how full a Carto was.
Now I know what you are going to say, I really want to try this out to double check your Math, But I dont Reload Ammunition so I dont have a Scale. And I not a member of the NRA so I dont know where to get one.
I dont see why something like this wouldnt work for what were doing here. 0.1 gram resolution should be fine.

Probably could pick one up a little cheaper if you did some searching. I just used this one because it had a good picture.
So now you have it. A very Technical method of determining who much juice is in or how much juice an eGo Carto needs to be full.

(BTW You can see what happens when the outside temperature goes over 100F and I am stuck inside for to many days. I tend too write Way too Much.)

Too bad we don't have the option to buy them in clear at least until we get use to filling them.
