Virtual laboratories are effective means in the development of professional skills. In their development, reality is ususlly mimicked in search of a better immersion experience with the design of hyper-realistic environments and interfaces which results in great complexity and high costs associated with its implementation. This study proposes a group of requirements to be considered in the design and production of virtual laboratories with a focus on the immersion experience in non-immersive contexts. These requirements consider design from a holistic perspective in favor of an immersion experience that considers dimensions such as didactic, external and internal authenticity, in correspondence with its relevance, attachment to reality and coherence. Two research cycles were carried out. In the first cycle, three research projects in the development of virtual laboratories were systematized and the requirements were defined. In the second cycle, the requirements were submitted to expert judgment through the Delphi method which allowed the proposal to be improved and validated. Finally, the definition of 22 immersion experience design requirements in the development of virtual laboratories was proposed. The result is particularly useful for developers and educators in designing learning experiences.
