[3dem] ruthenium tetroxide

[Frank Polzer]

Dear all,

 

I recently purchased RuO4 in aqueous solution (0.5%) from EMS which comes in
glass ampules.

 

Can anyone tell me how long after opening the ampules the RuO4 can be used
if being stored in dark and refrigerated?

 

Also, do you have any suggestion what sort of secondary container one could
use to store the opened glass ampules in the fridge?

 

 

Thank you very much for your help in advance.

 

Cheers,

 

Frank
