Bioreactors Types: Top 3 Types of Bioreactors

Wave bioreactor consists of a pre-sterilized flexible, plastic chamber that is partially filled with medium and inoculated with cells. The remaining part of the chamber is inflated with air. The air is continuously passaged through the head space during the cultivation mixing and mass transfers are achieved by rocking the chamber back and forth.
