Hi, all. We currently use elderly Spec 20s that are designed to take
rotocells so you can easily switch back and forth between the blank and
the sample. These are a great time-saver when we do absorption spectra
in our photosynthesis lab. I would like to get more Spec 20s but I was
told the new ones don't take rotocells. Do any of you know of a source
for used Spec 20s with rotocells? Or do you have any other suggestions?
Thanks for any help.
