[Histonet] storing paraformaldehyde under inert gas

[wjtang <@t> stanford.edu]

Hi,

We just ordered paraformaldehyde (crystalline form, Sigma P6148) and  
found out from the MSDS that it needs to be stored under inert gas at  
4C.  Does anyone know how to do store a reagent under inert gas?  Or  
does anyone do this at all w/ their paraformaldehyde?  I tried  
searching the Histonet archives and didn't find any info relating to  
storing the solid but maybe I used the wrong search terms.

Thanks in advance for any assistance!
