Like some here, I just bought Labogens SN and I'm anxious about the purity of the contents (even though it says 99% on the label) . Right now I haven't opened my SN but if I did open the container to test for purity, would the rest of the SN be wasted because its now become exposed to air? How long does it take for SN to go bad once its been exposed to air for a minute or so for testing purposes?
