  1. Effects of Heat on Nicotine Degradation

    by , 05-05-2014 at 04:08 PM
    I want to determine the best bath temperature for speed steeping ejuice via a hot water bath. I want to know the effects of heat on Nicotine concentration, i.e. am I sacrificing potency, and if so how much.

    Here is the Test Protocol I am using.

    • Make a large batch of 50/50 PG/VG with ~4% nic, no flavoring or other dilutants.
    • Fill four 1oz Boston Rounds with this mixture.
    • Mark one bottle as the "Control Sample" and set it aside.
    • Mark each of the other

  2. Speed Steeping - Ultrasonic vs Crock Pot Test

    by , 05-05-2014 at 02:34 PM
    I was curious if the steeping effect seen with an Ultrasonic Cleaner is just from heat (ie potentially from the cavitation heat), or if the Ultrasonic vibration contributes as well.

    So I did a controlled test.

    Test Parameters:

    • Mixed one 100ml batch of a Strawberry recipe.
    • Filled two identical blue glass Boston Round Bottles to the same exact level, right where the threaded neck starts.
    • Boston Rounds were approx 1oz. Put remainder of juice in a clear

    Co-ops 101

    What is a Co-op:
    A Co-op is where a group of people collectively combine their money to make a large purchase.

    Why do people do Co-ops:
    By combining funds, a large purchase can be made at wholesale prices. These wholesale orders usually have MOQ (minimum order quantity) requirements to qualify for the wholesale price. Co-ops are also used where a given product may ...

  4. Capillary Action

    by , 10-02-2013 at 07:14 PM
    Capillary action and Flow are two different things.

    To test capillary action set the wick straight up in some juice and see how high the juice climbs on the wick within a given period of time.

    Here is a demonstration I did of the capillary action of AO wicks.
    (I need to do a vid of SS wicks in the same style, I wonder if the green would show)


    Flow is very dependent upon the tilt. ...
  5. Ultrasonic Cleaners (in the context of speed steeping ejuice)

    by , 10-02-2013 at 07:05 PM
    There are 3 main types of UCs:

    1. The small cheap units
    2. Small Commercial Units often used in Dental offices
    3. Large industrial units.



    "Ultrasonic cleaners come in 3 categories, 1 the small toy like systems that are sold by companies for cleaning contact lenses, etc. These are very light duty cleaners with small transducers and very simple generators that are not very efficient."

    The Type 1 units will work but will take longer and the results ...
