Electric Juice does work well with bottom coil units, but I would have to say our preference is for top coil designs such as the Infinite Wick and cartomizers we include. The reason being that bottom coil units, after a bit of use tend to sit in a pool of spent residue which affects the taste of the vapor.
With the Infinite Wick for example, as you use it the residue tends so spray outward onto the walls of the tube sleeve and flow downward and away from the wick. You can then heat the wick to an immaculate clean quickly between drops to guarantee a clean flavor every time.
This allows you to use the Infinite Wick as a sampling tool in making EJuice. As you mix and dilute your extracts or even evaporate away your transport alcohol, you "taste" a drop or two on the Infinite Wick to check your progress.
You can also easily transition from one flavor of Ejuice to another quickly and conveniently.
Also in general with top coil units it is easier to see and access the heating coil if necessary. The reason our Infinite Wick and cartomizers sleeves are clear rather than solid back is that visualizing the wick and understanding what is happening is crucial for perfecting your vaping technique, especially for new comers.
Sorry to hear to about your troubles with winterizing, many users experience these difficulties which is why we took so much care in designing our system. The problem is that coffee filters work well for large amounts of boiling water, but with small quantities of sub-zero temperature ethanol the result is waste. The issues are:
- That coffee filters, like all paper, are naturally absorbent and soak up liquids that then can not easily be recovered.
- The pore size of a coffee filter is too small for this application.
- When ethanol is at freezing temperatures, it doesn't freeze but it does thicken and become increasingly viscous.
What happens you put all this together:
- Too large of a coffee filter is often used, resulting is a lot of liquid being soaked up and lost.
- The small pores quickly clog with wax particles and because the ethanol is slow moving at cold temperatures this quickly causes a pooling effect.
- Once pooling occurs, the ethanol begins to evaporate away (it is being wicked by the paper and evaporating away throughout the surface of the filter, so even in a freezer this occurs quicker than you would suspect) and the end result is that not much liquid makes it through the filter, and that considerable extract remains trapped in the paper fibers and on surface of the coffee filter.
We intentionally designed the Liquidizer for both extraction and winterization. The stainless steel cloth filter we use is very fine, but not nearly as fine as a coffee filter. Stainless steel cloth does not absorb and retain liquid like paper. It does wick away the liquid to some degree, but this is why we use a small square to keep the surface area over which this occurs to a minimum.
With our stainless steel filter the wax particles are caught yet the liquid ethanol still filters through easily, though also slowly, which is to be expected at low temperature. Also the assembly of steel tube, filter and beaker creates a small and hands free filtering stand (for photos see our instructions), which is critical because you do want to keep everything as cold as possible at all times, and only open the freezer door as necessary. A small increase in temperature quickly redissolves the wax into the ethanol.
The value of the Liquidizer is saving novice users from experiencing these growing pains. After all the work and expense of extracting and preparing top shelf herbal material, it's a shame to lose any of it to a coffee filter. The real pity is that many users who try coffee filters and fail become disillusioned on ever trying winterizing again, and forever miss out on regularly experiencing Virgin Ejuice.
It's our attention to detail and mindfulness of the complete experience that we hope "converts" users to adopting Ejuice. We look to streamline the process so users succeed and enjoy making their liquids, which leads to them getting better at it, which in turn leads to even better Ejuice, which creates a virtuous cycle through which a hobby becomes an art.
