Hi All
My Senior Science teacher has asked me to get some Selenium salts.
I have looked in Serrata and Westlab catalogues without success.
Any ideas? Please

Selenium powder, teacher only, class 6.1 toxic
Highly toxic by all routes of exposure. Avoid inhaling or contacting fine particles with skin. etc etc etc Why would you use it, but sorry this is not much help.
I would ring Serrata, they would know more about this Selenium Powder.
Good luck

ChemSupply have selenium in several forms. Selenium, black, powder; selenium dioxide; selenium standard solution (in nitric acid); and selenium mixture. The last two specify for determining nitrogen. Now if you can only get your teacher to figure out which one it is that he wants you might be able to order some in. However it is not up to you to do the thinking for your teacher. Selenium dioxide has a UN number and is Class 6, selenium standard solution has a UN number and is Class 8.

Watch the spoof movie "Evolution", where Head & Shoulders Shampoo saves the world, because of it's selenium content. We actually showed it (once) at the end of term, with a question sheet!
yep! Anti-dandruff shampoo is a source of selenium..
and I'll give you a tip - a lot of vets prescribe a selenium shampoo for dogs that have skin allergies. I have given up paying extra money for the vet product and buy the old fashioned dandruff shampoo instead, and I have found it is BRILLIANT at a flea wash!
shows how toxic it is when those little jumpers curl up and die and drop right off the hair..
AND my dog doesn't have dandruff
