As a graduated chemist and/or old CDL member we would like to offer you the opportunity to remain actively involved in the association and maintain connections with old acquaintances and fellow students. You can come to our ‘buitenleden’ drinks which are organised twice a year by the board for alumni or ‘buitenleden’. These activities are open for all members.

'Buitenlid' membership

CDL alumni can also choose to become a ‘buitenlid’. As ‘buitenlid’ you can go to the ‘buitenleden’ drinks for free and you will receive a Chimica Acta Lugduni (magazine of the CDL) especially made for ‘buitenleden’ with articles about old members, some fun articles from the Chimicas for students and an article about the past ‘buitenleden’ activities and drinks. Finally, a ‘buitenleden’ members activity will be organised once a year by the board.

Below are the advantages of the ‘buitenlid’ membership:

  • Two special ‘buitenleden’ drinks
  • A Chimica especially made for ‘buitenleden’
  • A ‘buitenleden’ activity

You will of course be kept informed of all the relevant news and the dates of the drinks. You can become a ‘buitenlid’ by paying a contribution of only 25 euros per year. If you have any questions or if you want to know more about the ‘buitenlid’ membership, contact the board via
