FAQ's: 

What's the difference between Student vs Instructor?

Both kits serve the same purpose, however the Student Kit are slightly stronger in concentration than the Instructor Kit because it is meant to be used drop-wise and simply used to experiment on a cup by cup basis.

The Instructor Kit is meant for doing larger trainings usually for groups of 12+ people and/or for Q-Instructors that need exact concentrations as required by the Coffee Quality Institute to run an official Q-Class. This kit is also used for the SCA Lab Certification.

Please note that the Instructor Kit is simply NOT a larger version of the Student Kit. They are meant for different purposes.
