Dear Colleagues:
I have to photograph the immunodiffusion plates. One of my colleagues has
a viewer with magnifier which works very well. It was made by Hyperion
of Miami. But they do not manufacture it anymore and I can't find this
type of viewer in any catalogs I have. Please tell me if you know where
I can buy such a viewer.
Thank you in advance for your help.
Have a nice day!
Akey :)
