CobraSnakeNecktie Posted September 16, 2014 Share Posted September 16, 2014 Union science on Suthep road lists it for sale on website. http://www.unionsci.com/%E0%B8%AA%E0%B8%B2%E0%B8%A3%E0%B9%80%E0%B8%84%E0%B8%A1%E0%B8%B5/%E0%B8%AA%E0%B8%B2%E0%B8%A3%E0%B9%80%E0%B8%84%E0%B8%A1%E0%B8%B5%E0%B8%97%E0%B8%B5%E0%B9%88%E0%B9%83%E0%B8%8A%E0%B9%89%E0%B9%83%E0%B8%99%E0%B8%AD%E0%B8%B8%E0%B8%95%E0%B8%AA%E0%B8%B2%E0%B8%AB%E0%B8%81%E0%B8%A3%E0%B8%A3%E0%B8%A1%20(%20Industrial%20Grade%20Chemicals%20).html Link to comment Share on other sites More sharing options...
Greenside Posted September 16, 2014 Share Posted September 16, 2014 I think World Chemical (next to the PSI building on Mahidol Road) has it as well. Link to comment Share on other sites More sharing options...

elektrified Posted September 16, 2014 Share Posted September 16, 2014 Isn't that what Thais always buy at the Thai markets (plastic shops) to put in the water tanks? I always see them buying these crystals - g/f included but she has never been able to find a good translation of what they are. A Thai friend said he thought it was lye in English but he wasn't 100% sure. Link to comment Share on other sites More sharing options...

DavidOxon Posted September 17, 2014 Author Share Posted September 17, 2014 Not food grade at Union either. (Didn't stop me trying it though, and no side effects yet that I've noticed!) Link to comment Share on other sites More sharing options...
quidnunc Posted September 17, 2014 Share Posted September 17, 2014 Not food grade at Union either. (Didn't stop me trying it though, and no side effects yet that I've noticed!) I believe it's reagent grade at Union Science. Reagent grade is purer than food grade. Link to comment Share on other sites More sharing options...
CobraSnakeNecktie Posted September 17, 2014 Share Posted September 17, 2014 Reagent grade is often purer than food grade but might contain stabilizers that could be a problem for human ingestion. Might want to check into that. What is OP using it for? Link to comment Share on other sites More sharing options...

bazza40 Posted September 28, 2014 Share Posted September 28, 2014 There is a chemical supply shop near the intersection of Suthep Road and Nimmanheimen Road. You would probably have to check the label specifications w.r.to heavy metals to determine whether the product conforms with "food grade". Usually, analytical reagent "A.R." grade specifications will be more stringent than food grade specs. Link to comment Share on other sites More sharing options...
