Regular 70% isopropyl alcohol will work for most cultivation purposes.

I use "pure grain" ethanol (everclear) in my alcohol burner. Works fine for me, plus I get to make some hooch from the leftovers :wink:.

some people prefer 70% as it dosent evaporate as quickly.

that seems like a waste of grain alcohol

dude you are wrong both work just fine in both applications
Dont say if you dont know, you will never get good rating that way.
i have used gallons of 70%alcohol to sanatize tools,filters,carboys,kegs,hoses,workspaces,countertops ect
as well as burnned gallons of it too

the 91% is good for extrations and if you have a small dish you are dipping something it to reclean over and over other wize you are just spending more money that you need too.

useing ethanol is just plan dumb you can get a quart of 70% isopropyl alcohol at just about any drugstore or supper market for 2 bucks
a quart of everclear is going to cost you closer to 20 bucks for many resons including the vice tax that is put on it before the sale tax, why pay vice tax for cleaner thats just not smart.

Man, did you even read the original post? He also asked what alcohol to use in his alcohol lamp. If you think you can burn your alcohol lamp off of 70% isopropyl, you're smoking crack. Who's the dumb one now. Read first, it'll save you from typing dumb shit later.  :rolleyes:

70% will work.. yes, but 91% evaporates quicker and therefore IMO is better for sterilizing gloveboxes, hands etc..


and you can not burn isopropyl alcohol in an alcohol lamp

I use the 70% rubbing alc.

Why, .....because it evaporates SLOWER.

Which allows it more time to sanitize something.

70% is a better sterilizer than 90% or even 100% alcohol, and at least three times less expensive. The reason is that the water helps 'wet' the surface of microbes, allowing better penetration of lipid envelopes than purer forms of alcohol. Propanol (isopropyl alcohol) is the most effective of the household alcohols, closely followed by ethanol. Methanol is a distant third, and more toxic to humans.

Re: alcohol [Re: agar]
    #5359281 - 03/02/06 08:02 PM (17 years, 10 months ago)

To each there own :smile:

The only time I use alcohol is for wiping down a glove box, my hands, or the points of needles.. everything else I use the PC and a quick swipe of 91% before contact

But I already said that both would work. He simply asked what type of alcohol to get and I said 91% because thats what I have :smile:

I never said that 70% doesn't work the same if not better.

Rubbing alcohol will produce a lot of soot(carbon) on your tools/needles if used in a lamp, regardless of whether it is 70, 91, or 99 percent. The correct alcohol to use in a lamp is denatured alcohol, found in the paint department at your local hardware store. And, not to nitpic, but alcohol doesn't sterilize anything. As agar correctly said, it is a sanitizer.

Denatured alcohol in one of these wickless models is PRIMO.

Ah, but I love to nitpick, RR. You're confusing sterilization with sterilizer. Sterilization is the complete eradication of all microbes. Sanitizing (also known as disinfecting) is their reduction by 99+%. Alcohol is not effective against bacterial spores, so could not be considered a sterilizer in that situation. But it is very effective in surface sterilization. Depending on the resulting effect, then, alcohol is either a sanitizer or a sterilizer. Likewise, hydrogen peroxide, phenol, chlorine, iodine, ozone, sodium hypochlorite, potassium permanganate, and quaternary ammoniums salts are either a sanitizer or a sterilizer, depending on the results in a given circumstance.

Ahem. Alcohol is not a sterilizer. It is a sanitizer. Big difference. Now, according to your post, how can alcohol be a surface 'sterilizer' if it isn't effective against bacterial spores, which just happen to be nearly everywhere, especially on surfaces?

OK so is it worth my time to wipe my needles with alcohol or is it pointless?

I keep all needles (in use) wrapped in alc soaked gauze pads.
That minimizes contact with open air.
Flaming needles is a PITA.

You can't call a particular disinfecting agent a sanitizer, disinfectant, or a sterilizer in absolute terms. It is dependent on the circumstance of its application. Sterilization, disinfection, and sanitization are defined in absolute terms, as scientific, medical, or governmental standards. Chemical disinfecting agents, on the other hand, can NOT be absolutely classified. It is relative to their concentration, length of contact time, and qualities of the microbe environment.

As for my statement that alcohol isn't effective against bacterial spores, I am wrong. I honestly meant to say that alcohol isn't very effective against bacterial spores. But, you got me, I mis-spoke. Relative to other chemical agents, and especially to UV radiation, alcohol is not as effective on spores as it is on other microbes. But, that is not to say that it doesn't kill spores given sufficient contact time. I don't claim alcohol to always be a sterilizer, but the simple fact is that alcohol is a sterilizer in some situations. Medical instruments soaked for 5 minutes in a 70% propanol solution are sterilized. In ethanol, it takes 15 minutes for sterility. See this link for reference. In certain circumstances even plain old soap can be a sterilizer. See previous link for reference. I don't even like to defend its sterilizing properties in most situations. But, your claim that it is only a sanitizer is flat wrong. It can be either (or neither).

GOOD LINK  :thumbup: :tongue:

Sanitize means  to reduce the number of contaminants to a safe or relatively safe level as may be judged by public health requirements.

Disinfect means elimination of all recognized pathogenic microorganism  but not necessarily all microbial forms.

Sterilize means  the destruction of all microbical life  by use of chemical or physical procedures.
