What does 'LR' mean on the SN bottle

Just curious
Just found out it means Laboratory Reagent so nevermind

My (limited) understanding is it's an abbreviation used to grade purity of chemicals so labs know what type of chemical is best suited to what type of lab work, but I'm not a chemist… so…

LR = Laboratory Reagent.

AR is used for sophisticated instruments and for research activities which accuracy is so important. However, for teaching purpose you may use LR chemicals or sometimes industrial reagent (IR). LR grade can be used for general purposes and again sometimes, these can be used teaching purpose.
So AR grade is the purer one.

So let me understand this, if you get SN labeled LR, then it won't work? I'd like to get clarification on this because that means OP might fail. That is if it doesn't just stand for Laboratory reagent. Kinda seeing two different replies here.

So I can't use LR to ctb?

Mine is 97% pure and apparently PPHB says anything greater than 95% should get the job done https://sanctioned-suicide.net/threads/96-pure-sn.52173/

U can use it it's pure but the grade AR is better, if u managed to get it it'll be great. How much purity btw, do u have a certificate of analysis?

I don't have a certificate of analysis but it says 97%. I read that youx can test it using a drop of blood (it's supposed to turn brown or sth). Can I test it like this?

Blood test isn't accurate and nitrate can pass it, better test it with aquarium test strips, 97% is fine, if your sn from a reputable chemical company u can go ahead to their website and and then Search for your product, then you will find all the details, including the percentage of impurities and what the remaining 3% contains. Is the CAS number written on it (7632-0-00)?

It's 97% pure, so it shouldn't matter what impurities there are for the remaining 3%, right? It'll poison you just the same. The impurities only matter for lab work

Yes, sure, I know someone who died by SN %96

I appreciate you asking this question, now I don't have to LOL
