Below is a list of Cleanrooms manufacturers from Louisiana. Clean rooms are rooms designed in order to allow for the control of airborne particle concentration. They were invented for aerospace and microtechnology in the early 1960s as the United States and other countries geared up for the Space Race. Rapid advancements were being made in the fields of technology and biochemistry as scientists and researchers began working on smaller and smaller levels, and as a result scientists and manufacturers required more and more rigidly controlled working environments.
