Overview

Stainless Steel Bioreactor LMSSB-A101 has a total capacity of 30L with a working volume of 21L. Allows for efficient mixing, aeration, and enough headspace for proper gas exchange during fermentation. Equipped with jacketed water bath to control the temperature of the surrounding. Integrated control of temperature, stirring speed, pH, dissolved oxygen, antifoam, feeding, aeration, and pressure enables stable and reproducible fermentation conditions. Our Stainless Steel Bioreactor is ideal for fermentation and bioproduction and is widely used in industries such as pharmaceuticals, food, energy, agriculture, and scientific research.
