Ethanol used in Vapourisers

[DaveG NZ]

Hi All

I've bought a vapouriser to use with Ethanol and Oxalic Acid to treat varroa.
I can only seem to find denatured ethanol - that is ethanol with a small amount of bitrex - an agent that makes the ethanol bitter (presumably so that people don't consume it)
Has anyone used denatured ethanol when used with oxalic acid treatment? Any side effects?

Thanks
Dave

What point is there for the use of any ethanol? Ethanol evapotates at 78C, oxalic sublimes at atound twice that. Seems pointless.

Do not use any more chemicals than necessary. Your honey might even taste of bitrex - who knows!

How does the vaporiser work???

Have you thought about using Vodka?

Ethanol also burns rather well so would keep well away from vaper.
Can see no reason to use it for vaporising as Oliver pointed out.

Ethanol is used as a solvent when things don't dissolve well in water. Maybe that is where this
originates as to make oxalic acid solution for dribbling it needs to be dissolved. But if all you
are doing is changing state as in vaporising then no need for ethanol.

L.p.I think this is what he is talking about.

That is a different type of vaporiser to what most on here will be using where a heated metal pan is used.
Presumably ethanol is being used as it evaporates easily so working in a different way.

It is a fogger,
Anyone remember fgmo? BTW, what ever happened to the good Dr!

Yes...and a waste of time that was.

Don't know... but I think he must be over a hundred now if he's still around.

Varomor vaporiser used ethanol 95% as a carrier solvent for the OA... 2 pumps of 20ml per vaporisation injects 2g of vaporised OA into the hive ( 1g OA per 20ml Ethanol)

Cheaper to use water as the diluent fo OA... but most of the injector type vaporisers ( Foggers) suggest using Thymol in the mix.. which will dissolve in alcohol, but not water


Vodka in UK shops is proofed ( ie water is added) to approx 40 by volume ethanol.
Back in the second half of the last century our Pathology dept had a " bonded" store for Ethanol... in sealed red cans.. marker 70 OP and 95 OP ( OP= over proof)

Proofing was the benchmark use to access the purity of the alcohol... when proofed .. ie the percentage of water needed to be added to the alcohol to prevent gunpowder igniting..it was ready for sale!

I think 95% ethanol alcohol for laboratory is available under licence in the UK.

It's an insecticide fogger!

The Yanks love these, from "Agent orange" to "swingfog" They've been killing everything "abroad/overseas" for years.

And by the sound of his coughing in the vid, they've brought it home to the good old US of A!

Thanks but I'll stick to humping my car battery around & delivering the vapour directly to the inside of an enclosed hive.




Oh, and the military version of that vaporiser was much longer putting the operator at a safer distance from the 5h!te coming out the end. First time I've known the military to be leading on the old safety Elf!

Utter fairytale from somewhere!

Rum kept as ship's supply was held under lock and key by a member of the crew. To be sure the key holder was not short changing the crew by doling out diluted rum, the test was to see if the rum would burn if set on fire. Only the correct (or higher) alcohol content would burn in the tumbler. If it did burn it was deemed 100% proof that it had not been diluted. If it didn't burn it was deemed 100% proof that the key holder was cheating the crew - and he may well have 'walked the plank' for his crime!

It is not safe to dispense drinks with a too high ABV as the drink can burn with an invisible flame and seriously injure a drinker. Anyone distilling alcohol should have a bucket of water handy, should there be a leak (or spillage) and a fire. The water is used to dilute the alcohol and so extinguishes the flames. Some bootleggers might need more than a bucketful of water to douse their fires!

That scale meant that 100% alcohol would have a proof of 180. It has since been modified such that pure alcohol was designated as 200% proof. We now use ABV as the measure of alcohol content - Alcohol By Volume.

From memory about 54% ABV spirits will burn.
