Hi Everyone! Does ANYONE have a link to a chart or happen to know the shelf-life of various prepared media? I work in a micro lab, and sometimes like to make plates before I'll need it (even months) I'm aware that TSA, TSB, NUTRIENT AGAR AND NUTRIENT BROTH all have a prepared medium life span of 6months+, however what about the following media: -Spirit Blue Agar -MacConkey -Hektoen -Mannitol Salt Agar -Urea Broth Thanks a Bunch, Jasmine
