Chemisch Dispuut Leiden (CDL) is the study association for the bachelor Molecular Science & Technology (MST) at Leiden University and TU Delft and the master Chemistry at Leiden University. The CDL was founded on the 20th of May 1926. The association organises many academic, career related and social activities throughout the year, including company visits, lectures, parties and study trips to other countries. The boardroom or 'hok' of the CDL is located in the hallway between the Huygens building and the LMUY and is open every day from 09:00 a.m. till 05:00 p.m. So come by to have a free cup of coffee or tea, to ask your questions to the CDL board, to see which activities are organised or just to relax and chat with your fellow students!  If you are interested in joining the association you can send an email to or drop by at the CDL boardroom!
