Prompt please what is the time it is possible to store or keep dissolved or divorced NAN? Thanks.

For conservation of all useful properties of an admixture is better to not warm up repeatedly it or her, the storage time therefore is optimum at a room temperature - 2 hours, in a refrigeration cabinet - no more than day.
