@lukaszz12 ,
For me that's cheap. And 50 is more than enough. Could you tell me how I can actually get it ? Traveling to Poland is a bit much, and I can't read the Polish language. I recall a Polish seller on Ebay, but I haven't seen that for some time.
In Europe: large chemical suppliers offer it. They usually want a business name, state that they cannot sell to individuals and mention restrictions.
Even that thistlescientific company that doesn't explicitly state selling sodium azide is restricted wants a company name, name/address, telephone number. I know I could try, but ... Earlier this year (before the REACH guidelines came into effect) it was easy.
To all: what do you have to do these days to get sodium azide in Europe ? I really have to narrow this down to a few doable options.
