Chem21Labs works within the policies of the various user-institutions to collect and disseminate royalties. If the institution has created their own lab book and they allow Chem21Labs to deliver the lab book as a pdf to their students, we can collect a royalty for the lab authors and/or university. About half of Chem21Labs user-institutions do not include a royalty in the cost their students pay to Chem21Labs. For the other half, the royalty averages $5 per student per semester and the royalty is paid out as directed by the institution when the semester is 2/3 completed.
Some universities use this royalty to fund travel costs for upperclassmen to present their research at ACS regional and national meetings.
