Michael J. Benedik

They should be good for many months. I would suggest you keep them somewhat dark though for longer term storage.

Alejandro Martin

I know it is only anecdotal, but I've kept them for over a year without a noticeable drop in performance for routine tasks (streaking bacterial/yeast stocks, plating transformations, etc).

Hope it helps!

Laurence Stuart Dawkins-Hall

Agreed. They can be stored for months
Just though make sure Durans are sealed otherwise things can start to grow !!
