We stimulate the 3Rs of Replacement, Reduction and Refinement - in that order

To reduce the use of laboratory animals in research and education, the 3Rs Centre Utrecht (3RCU) stimulates the 3Rs of Replacement, Reduction and Refinement – in that order. This website provides centralised information about the 3Rs and access to 3Rs tools. Additionally, you can find information about initiatives of the 3RCU. Our philosophy can be summarized as ‘ideas supported by data’, and we facilitate many targeted actions. Read more about our mission.
