DPIP Lab Set Up

Below are the pictures of the set up for the DPIP lab. You have used a spectrophotometer before, however this time you will be measuring transmission, instead of absorbance.

Paper chromatography set up.  Reminder: you can read about paper chromatography and see an animation here.

Chloroplasts and DPIP on ice.  Note: I pulled the vials out of the ice for the picture,  however these should remain buried under ice when not in use.
