Anyone ever use racks for 4x5 development?

Hello,

I recall in the before time using these "Em Film Developing Racks" to develop 4x5 film from TEMs (transmission electron microscopes).
(check a ways down this page)

Anyone ever use this for regular 4x5's?

Notice that they make one in white--easier to see in a safelight...

I have a smaller version I got somewhere really cheap. Used it a few times then went back to the stainless 4 up racks. They are just easier to load in total darkness. Trying to align the film in the slots in total darkness was a real pain. If you mis-align then lift the carrier to aggitate or pull it from the chemestry the film dislodges or bows makes it vulnerable to damage.

Thanks for the comment. This explains a lot.

As it turns out, electron-sensitive film can be used in a safe light.

I also remember using electron sensitive plates! I thought it was one of the last plate microscopes, but they sell plate--film adapters on that website.
