Morris Reagent Stability?

[Didgital]

Was just curious if anyone could tell me the shelf life and best storage conditions for the Morris reagent?

I've had mine for a year and it still works.

It's stored in the cardboard box that it was mailed in to me by dance safe. In a plastic tub in my closet.

The only reagent that I suspected it wasn't working was Marquis.

So that would be Ehrlich, Morris, Simon's, Froehde, & Liebermann.

When I went back and read it said that even if the Marquis is discolored it should still work. I think I had a no react and that's why I threw it away.

And it's going on. Oh I don't know 16 or 17 months.

I know for certain that the reagents are working because I got exactly what should be expected from a, (but I'm using loosely) reference sample of methamphetamine.

And I test on reference samples like aspirin, acetaminophen, a codeine pill you know just to make sure that they're still working.
