Sorry to hear about your membranebox Sean. But Ghubara is a bleeder and I never put a ruster or bleeder in a membranebox because they will stain the polyurethane membranes permanently (on a good note, Ron H. used to replace them for me, or broken latches before he passed).

Also, if you live in a highly humid environment like I do, then you don't want to be using membrane boxes for certain kinds of specimens because they will trap the humidity inside. I typically mount and store specimens I keep in membrane boxes in my institute office, which is kept in climate controlled AC 24 hours a day.

Tracy, I've never experienced a membrane getting cloudy. But as I mentioned before, all membrane boxes are kept in an air conditioned office. I have membrane boxes over five years old that are in the same condition as new ones, both enclosing specimens of all kinds and never used.

Other than the aforementioned issues, membrane boxes are a great solution to storage, protection and display of specimens.

The membrane is starting to degrade and go cloudy, and in at least one specimen (Imilac, bought at Tucson, I forget the year) the membrane has ruptured and the slice is rattling around loose in the box. Has anyone else had this happen to their specimens?
