What is Medical Grade Butane ? What is the difference between medical grade butane and the butane that is in the cans?

I was wondering cause this person told me they use 99.5% certified medical grade butane ( he said you have to buy it from a gas supplier and it comes by the tank ) and it isn't the same as what's in the cans. He told me the cans contain iso butane , propane and other solvents that you shouldn't be making dabs with (some type of chemical to make a smell). That's why I am wondering if this is true or baloney.

and actually propane and iso are solvents that can be used, it is the mystery oil and the perfume they put in the cans that make them questionable.

99.5% n-Butane is Instrument Grade. I'm unaware of any medical grades available under that designation.

Your friend has been misled. Lighter butane is typically a mixture of propane, n-butane, and Isobutane. They aren't added for smell, they are added for performance and both do a fine job of extraction in their own right.

Your friend may be confusing them with mercaptans, added to some LPG for leak detection, which are not used in lighter butane because of the garlicy taste and smell.

Both the 99.5% Instrument Grade and the lighter fuel, will have some molecules in them longer than butane's four carbon chain (MO), and should be vacuum distilled before using them to remove them.

Thanks for clearing it up, sounds like the lighter butane is just as good or better than the tank.

no such thing as medical grade. Its a deceptive marketing attempt. In the medical industry hexane NOT butane is used. the best butane to use in the U.S. is Lucienne. it also happens to be relatively cheap. Graywolf over at skunkpharms has a link up of all the butanes theyve tested

Wanted to add if you do see a gas supplier for butane you want to ask for R-600 refrigerant

The guy doesn't know what he is talking about......first of all,research only comes in high purity or assay .i.e.99.999% other than that you can get refrigerent grade or instrument grade at 90% 99.5% or 99.9%....grade and assay are not mutually exclusive.........refrigerent,instrument,and research are the grades you are gonna find for N-butane and iso-butane for that matter.nothing wrong with iso,just different temperature characteristics.what mtaters is what is left in the end product,not what you make make the oil with.........there is no such thing as "medical grade"N-butane.......it would be "pharmaceutical grade" if it were being used to make medicine.....it's medical grade if it's being used to treat a person....of course,in the pharmaceutical industry they would use "research grade".don't feel bad,I have a recreational lab lisc in washington and the guy that worked for the gas company didn't know much about grades........bottom line,don't wast your time buying local.go to the guys that skunkpharm listscon their site.that's where most of us go.best price and quality gas you are gonna find

Your friend appears to be suffering from too much of his own product or the rarefied atmosphere at his location.

99.5% is Instrument grade. You can get 99.9999% HPLC grade, but I'm not aware of any medical grades.

They don't add mercaptans to lighter butane as an odorant.
