Use of Ether in the Fab

Hi Ed, et al --

I believe John said that he heard another chemical involved in thie 
incident was sodium azide. 

Sodium azide is sort of like ether in that people take it for granted -- 
for example, you may use a lot of ether if you're working with lipids 
and self-assembling systems -- sodium azide is commonly added to 
solutions of DNA, for example, to prevent fungal and bacterial growth, 
and is often added just as a matter of course

I don't think that anyone would request this, but we might consider 
adding it to the list, because I do have some concern that someone might 
think it's pretty innocuous (and it is, in the concentrations used as a 
preservative) and decide to mix some up.
