Basics of Bioreactor - Quiz I

What is bioreactor?

• A large receptacle or storage chamber, especially for liquid or gas.
• An apparatus used for biochemical reaction or process in industrial to produce biological product
• Vessels designed to contain chemical reaction
•  Essential item used in distillation of liquid mixtures so as to separate the mixture into its component parts, or fractions, based on the differences in volatilities.
