The EB&T research group has an array of 6 climate rooms in which temperature and light cycle can be adjusted to the prefered test conditions and/or test organism. All rooms have recently been upgraded with new control units and cooling and heating systems. The flexible infrastructure of these climate rooms allows us to perform scientific research on a wide variety of test organisms such as fresh and marine species of algae, invertebrates (Daphnia, Artemia,...) and fish (Carp, Zebrafish, Sea bass, ...).
