Day of open laboratories (TOL)

Registration deadline for the event is May 09, 2024. Late registrations (e.g. for the waiting list, in case the event is fully booked) should be sent via e-mail to

The Open Laboratories Day (TOL) 2024 is designed for students aged 16-19. Younger students cannot be admitted.

A basic knowledge of chemistry is required to follow the event;

The event is planned and carried out as a full-day event: It consists of five short lectures, 4 lab stations (per student) from a pool of 10 and an experiment show. It is not possible to attend individual parts of the event.

The number of participants is limited. If the event is fully booked, we recommend that you register on the waiting list, as experience has shown that there are usually changes in the run-up to the event;

The group allocation for the laboratory stations is carried out by the organization team. Each student will receive a letter at the registration desk on site. Students from the same classes may end-up in different groups. We ask for your understanding.  

During the registration process, D-CHAB points out that photographs and, if applicable, video recordings (including sound) will be made by ETH Zurich or D-CHAB during the event for communication and marketing purposes. The material created may be used by ETH Zurich for various channels (print, online, social media, events, etc.) without restriction in terms of time, space and subject matter. The authorization includes all current and future rights of use. Financial claims against ETH Zurich and third parties (photographer) are excluded.
