In days of old there was the Klett Colorimeter. It measured in "Klett units"
rather than OD. I think because the tubes used were not square so path length
was not fixed. They were popular in student labs since it was almost
impossible to destroy them. Oh, I just saw that you can still buy them!
Do cost a bit more now.
