Title: Sources for acid
Post by: jaybeerman on March 02, 2011, 10:01:21 PM
I'm looking for a good source of food grade phosphoric or lactic acid (88%, not 10%) preferably in a container larger than 4 oz.  Unfortunately my local won't consistently carry acid.  Let me know if you have a proven source.  Thanks, j

;D

Can you have your LHBS order it for you?  I suppose ordering multiple 4 oz bottles would be annoying.

Our club is about to purchase 950 ml bottles of 75% phosphoric from DudaDiesel.com.  They say it is food-grade stuff. 

The thing about acids and shipping is that DOT has a limit on the size or quantity of hazardous materials that can be shipped in the package before it has to be shipped as Hazardous Cargo.  Of course, the cost sky rockets at that point. 

For acids, the hazardous quantity is 1 gallon if my memory serves me correctly.   So you would have to limit the amount per shipment to that amount to avoid the shipping surcharge.

yeah this is what I'm trying to avoid.   I don't think I need a gallon but a quart would be great.  Next stop, local brewpubs.  I do love my lhbs but they're mom/pop and they don't even bother with the technical stuff.

That's a good price ($13.75).  Good find Martin.

Thank you for the guilt ridden  ;) suggestion Denny,  cynmar is a great source that I always forget about.  Wow martin/tom, 13.75 is indeed a good find.

Martin, I can purchase a gallon from the local 5 star chemical guys for a slightly better price, I wonder if you guys could do the same.  I guess I need to find and educate enough local brewers to start a real brewing club, then we can split a gallon too.  Cheers, j

Too funny.  :D  

I did a little research on food grade phosphoric acid and came up with the same thing Martin referred to...dudadiesel
950mL @ 75% for $13.75 seems to be the way to go.

You may not be able to get this from Cynmar. If my memory serves me right, the only chemicals the public can by are calibration buffers and stains. If you have an account with the and convinced them that you are not a terrorist, you can get all sorts of stuff that I had to steal from the chem lab when I was a kid.

It is good to have a lab and an account with Fisher Scientific...

Yeah this has been my experience in the past, with a number of other companies.  There is a business that I can order some things through; I've not tried to get acid from Cynmar yet. I can visualize a kid having to stealing stuff from a chem lab, that's very funny.  I did finally order some though it won’t get here till Tuesday and I was hoping to brew today.  Thanks (to everyone else too) for the help, j

Yesterday I thought I'd check at a "grow" store to see if they carried phos/lactic acid.  :D  There's nothing like having a 20yo, (new)hippie treat you like you're a moron and/or a terrorist.  After making a huge scene, telling me that "acid should never be put in a beer...you should never drink that stuff," I left without finding out if they carried the acid or not.

Maybe they'll ship some to you? I also get my pH meter storage and buffer solutions from them.
