Wet labs vs dry labs from lab design experts CRB

Dry labs are focused on computation, physics, and engineering. Each type is best described by the science that is conducted within. Each has a purpose. The science that begins in a dry lab is often confirmed in a wet lab. Even still, results achieved in a wet lab can contribute to continued development in a dry lab.
