... would it be possible to extract THC only, by pulling faster, keeping the temperature below the flash point of CBD, and then revaping later, pulling slowly, extracting the CBD? Or vaping slowly the first time, getting THC and CBD.
What temperature is the MFLB when pulling relatively fast, and what is the temperature when pulling much more slowly?
Has anyone tested it out to see if a faster/slower pulling speed gives a more heady or body high?
Hi,
It is possible to use the Box to try to separate out different components while in use. However, the Box itself was not really designed for that process -- actually the opposite is somewhat more the case. To get just one component at a time, a desktop unit would probably be a better choice, even though there are none on the market now that have anywhere near the accuracy that would be needed. To really do this right, you would need lab gear.
In regards to your other questions, I have included some information below which I think will be particularly helpful. I have been wanting to post the following information/graphs for some while now. I was finally able to get the legal release necessary since the following test results are usually considered to be for "internal use only" within our company.
Note: All tests below were performed with a freshly charged stock battery. The graphs were taken from our unit calibration test bench PC which is fitted with an infrared imaging system specific to our manufacturing process. The measured temperature is that which would be found at the exact contact surface of the very bottom of the screen trough, and thus represents the real operating conditions within the Box chamber while in use.
This first graph shows how quickly the Launch Box heats up and cools off. In this test, power is applied to a fully cold box for exactly 5 seconds under no draw conditions. You can see how quickly the unit rises to the required temperature. These measurements, typical to our units, is the physical basis of our claim "From cold to 385F in under 5 seconds!".
This second test is similar to the above, except that the battery was applied for 10 seconds. In this test (and also above) you can also how fast the unit cools off when the battery is removed. This characteristic is one of the reasons that the Box is so efficient when in actual usage. Vapor is truly only produced when the battery is applied. Within seconds of battery removal, vapor production halts completely, ensuring that none is being wasted when there is no drawing going on. Ours is the ONLY vaporizer in the world that can do this!
This third test, with 15 seconds of power, demonstrates the thermal stability of the Unit. The key thing to notice in the three graphs above is the demonstration of our key design integration of physics of the StefanBoltzmann law. (see
http://en.wikipedia.org/wiki/Stefan–Boltzmann_law for more information). The specific physical characteristics of the materials chosen in the design, the exact physical shape within the bowl area, and the IR relations of the component parts, all contribute to a 'self titration' effect when the unit approaches the optimum working temperature.
These three graphs together demonstrate the fact that
despite the extremely rapid rise time in the temperature of the unit, there
is not also created the conditions of thermal runaway. The naive approach of simply applying "more power" just will not work -- a much more delicate balance is required (hence our utility patents in this area). Instead simply increasing temperature indefinitely, the physics of the unit stabilizes the temperature, therefore enabling the user to easily access the optimum vapor production. This allows ordinary people to use the Box with a minimum of, training, effort, or skill. Without the temperature stabilization effect, it would be nearly impossible for anyone but people with the most advanced and split second accurate breath control to get the draw rate correct.
This is part of the "Magic" of Magic-Flight. Although the Box may look like a simple block of wood, there is a actually a rather high level of physical sophistication inherent the design, most of which is not at all apparent to the casual viewer.
This next test demonstrates the effect on temperature of a "normal" draw -- ie that which is obtained from a person who is encountering the Box for the very first time and which has not otherwise been trained or instructed. People usually draw too fast when they are using the Box for the very first time, thus resulting in a cool off below the range generally useful for vaporization. As such, we encourage people to try drawing "very slow", and "slower than you might expect" when using the Box for the very first time. These directions, and better, an in-person demonstration of the correct draw rate goes a long way to improving the chances that someone will get effects when first "testing" the Box. Without this guidance (ie for those people who insist on trying the Box without reading the directions), there is a much greater chance that they will not feel the Box as "effective".
This graph shows the effect of a correct, steady calibrated draw rate. Using a vacuum system with a rate of flow control valve, etc, we test the unit by applying energy for 5 seconds, simulate a draw for 10 seconds, and then no_draw for 5 seconds more before removing the battery. This test simulates the normal usage conditions of a person who hit the Box with a little bit more experience than the novice user above. As you can see from the graph, a steady draw rate can easily set the temperature to a specific range. This feature allows users to "tune" their experience with the Box by trying various draw rates.
This next graph shows the full range of variability that the draw rate can have on the temperature of the Box. This test demonstrates the effect on temperature that a full hard draw can have. Since the draw rate can effectively vary from zero (which would look like the no-draw graphs above), to the maximum airflow that a normal person can pull through a Box, this graph shows the range of accessible temperatures. As you can see, pulling air through the Box too fast, as some Bong users are prone to do, can make the vaporization process stop completely. When people say the Box "does not work for them" or that the "effect is different" than they want, it is usually due to some factor like this one.
This final graph shows the result of one of the more sophisticated "optimal" hitting techniques. The procedure of "micro-hitting" is to take multiple short very light pulls of air every second or so. This allows the temperature within the Box to fully cross all points within the optimum range, ensuring a release of *all* of the different types of active ingredients in a set of proportions similar to their actual rates and proportions of occurrence within the load. Insofar as different volatile components are released at different temperatures, the unique capability of the Box to nearly instantaneously adjust its level of heat provides a release of these components in their natural proportions.
Vaporizers which are set to only one temperature at a time cannot help but volatilize the lighter components first and quickly, while leaving behind other, higher temperature components. Such units cannot help but produce too much of the lighter parts and not enough of the richer ones in relative proportion to one another. Unlike these other vaporizers which can only change their temperature slowly, or only via purely mechanical means, the full spectrum of effects is available with the Box in their natural proportions. Again, the Box is the ONLY vaporizer on the market that can come anywhere near to being able to do this.
I hope that this information has been helpful.

EDIT ADDED LATER: In regards to the graphs, read the graphs from right to left! The red dot on the left is the "current" temperature and the entire trace moves towards the right. The X axis is the measurement at a certain "time ago" -- exactly backwards what most people might expect. Also, the time on the graph should be read as relative -- the image capture was not synchronized with the calibration clock.
The way to look at the graphs is to take the time of power being applied as being where the curve makes a sharp increase on the rightmost side of the graph, and then to consider the "progress" of what happens as you move towards the left from there.
