Hi Guys,
Our R&D team had a good look into these questions and had some fun answering them.
The reason it took so long was to insure the information is correct.
@ The_Algebraist
The iolite vapouriser is not supposed to come supplied with butane. However the shop where you bought it might have filled it with butane for demonstrating purposes. You also mentioned that you inadvertently popped the herb chamber open and spilled your herb. For your information the herb chamber will have a locking mechanism in future models. We can?t at the moment make this a feature on the current models chassis.

1) I have noticed that the brand/quality of butane used affects the intensity of the orange glow and seems to affect the duration of the warming cycles (please feel free to correct me if I am wrong, Iolite ).
All butane contains a certain small amount of propane. Different brand will have different amounts of propane and the higher the amount of propane the more intense the glow will be.
If you stick to mainstream brands such as Colibri, Braun, Newport Gas and Ronson in Europe you should be fine.

just wondering, about how long does a normal can of Vector (or other good quality butane) usually last you guys?
The iolite vapouriser uses 1 gram of gas per hour. Millilitres and grams are the same. So if you bought a can of 250ml it should last for 250 hours.

The health effects of CO depend on the
level of CO, length of exposure, and the overall level of exposure in the atmosphere.
I need to clarify the difference between
exhaust gas and vapour gas and stress that they do not mix as your lips are on the outlet at the time of inhaling. People don?t inhale through their nose at the same time as pulling on a cigarette. The chambers are completely separate and you don?t suck in the fumes from the exhaust.
Butane is commonly used in cookers in kitchens, and the quantities burned are much greater and exposure is much higher due to the sheer volumes been used. It is also important to stress that the air-butane mixture is oxygen rich and along with the catalyst you get as close to complete combustion.
Since we draw attention to a gas cooker as a comparative source of CO generation, I think it might also be beneficial to point out a further difference, which is the iolite vapouriser is not running continuously. The run time per minute at say ambient temp of 20 degrees C indoors with a full herb chamber would typically be 5 seconds on 45 seconds off due to the controlling action of the thermostat. I think this also demonstrates the inability of the iolite to generate meaningful amounts of Co when it is immediately mixed with the surrounding atmosphere.
The health effects of CO depend on the
level of CO, length of exposure, and the overall level of exposure in the atmosphere. To reach levels of CO you need to pump a lot of it into a room to get the concentration up. If you produce some CO in the exhaust fumes it will diffuse very rapidly into the rest of the air that fills the room if it is indoors. The only way of getting high CO exposure would be to continually inhale ALL of the exhaust fumes for a LONG TIME. This in itself is imposable as the exhaust gases instantly mix with the atmosphere as they exit the device and hit the diffusion manifold (clear component in the cooling fins.)
If we examine the start up procedure as illustrated in the instructions you will find that the only time butane is exhausted is for a few seconds pre-ignition (This is the same for when domestic gas cookers are ignited with piezo-ignition, except that with gas cookers the volumes of butane and the exhaust gases involved are much larger).
Switch on
iolite?s flameless catalytic heater is activated by a piezo-electric system. Firstly switch on the on/off gas button. Then switch on the catalytic heater by slowly pushing the piezo switch forward. The sound of the gas flow changes to a mild ?roar? confirming your vapouriser is heating up. This usually happens on a first try, if by chance the piezo fails the first time; depress the switch again within 5 seconds.
As illustrated, an orange glow will also become visible after a few moments to confirm the vapouriser is heating up. It will disappear once the optimum controlled temperature is reached. This is because the iolite vapouriser is thermostatically controlled; ensuring the optimum temperature for herb vaporization and efficient use of both herbs and butane. Note that during its normal working cycle, the sound made by the vapouriser when ?On? is cut in and out by the thermostat.
Depending on your herbs allow at least 45 seconds for your iolite vapouriser to reach it?s controlled operational temperature of 190C before inhaling. This doesn?t necessarily mean herbs will release vapors after 45 seconds. You may have to wait a little longer. The length of time to release herbal vapors will ultimately depend on your herb type and its moisture content. 190C is the maximum temperature reached; so it is impossible for any combustion or burning to occur. When finished switch the unit off using the on/off gas button
What are the Allowable (Legal) Limits for CO?
Occupational Safety & Health Administration, USA (OSHA) (for industrial situations) - Permissible Exposure Limit (PEL, by TWA) - 50 ppm, 8 hrs.
Old PEL Standard (by TWA) - 35 ppm, 8 hrs.
Threshold Limit Value (TLV, by TWA) - 25 ppm (29 mg/cu. m) (recommended by American Conference of Governmental & Industrial Hygienists [ACGIH]; Ceiling (max. value, 15 min.) - 200 ppm (229 mg/cu. m))
Michigan Occupational Safety & Health Administration (MIOSHA) - PEL (Industry, by TWA) - 35 ppm, 8 hrs. (38.5 mg/cu. m); PEL (Construction, by TWA) - 50 ppm, 8 hrs. (55 mg/cu. m); Ceiling (max. value) - 200 ppm (229 mg/cu. m)
Environmental Protection Agency, USA (EPA) - Domestic, outdoor air, all ages (TWA) - 9 ppm*, 8 hrs., Domestic, outdoor air, all ages (TWA) - 35 ppm, 1 hr.
World Health Organization (WHO) - Domestic, outdoor air, all ages (TWA) - 9 ppm*, 8 hrs.
American Gas Association - Indoor air (leakage at a heat register) - 15 ppm
American Society of Heating, Refrigeration & Air Conditioning Engineers (ASHRAE) - Indoor air (leakage at a heat register) - 9 ppm
TWA - Computed by making measurements at intervals over 8 hours, then adding the sums of the concentrations and the intervals, and dividing by 8 hours (480 min.).

Domestic gas cookers, with much larger volumes of butane been burned, are permitted and used widely around the world. Our product uses volumes that are extremely low compared to domestic gas powered cookers and gas powered domestic fires used for space heating in peoples homes.
Therefore to answer your question on Carbon Monoxide your tester showed your iolite to be giving off and considering the size of these units and the gas flow rate concerned which passes through a flameless catalytic heater. We would have to ask in terms of measuring the ppm levels,..
How was the concentration measured?
What type of equipment was used, make and model?
Have you calibration certificates and traceability?
Have you used a standardised test procedure (ISO etc.)?
How were the test volumes controlled and measured?
What was the test environment?
Was the person carrying out the test qualified to do so, qualified to draw such conclusions and qualified to publicise such conclusions on a public forum?
@ frogbmth
That picture of an iolite fitted with a mix?n?ball J adapter is very interesting. Is that adapter made out of plastic or aluminium? Also what do you mean by a tighter vape? Is it because the pressure drop increases and therefore harder to draw upon?

Picture a refillable butane canister about the size of a chapstick (that way one could buy a large canister of quality butane and bring just enough to fill the IoL a few times--it would fit nicely in the IoL case with the unit and ones herbs)
..
That?s very nice idea but I don?t think we could foresee making such a device. We can?t see the enough quantities sold to make it cost effective especially with our standards that would need to be applied.
All the Best
