Stainless Steel Mechanical Stirring Bioreactor and Related Concepts

A Stainless Steel Mechanical Stirring Bioreactor is a type of vessel made of stainless steel, equipped with a mechanical stirring mechanism to ensure uniform mixing of the contents during a biological process.

The mechanical stirrer consists of an impeller driven by a motor. The impeller rotates at a controlled speed, causing the liquid and any suspended cells or substances to move, ensuring homogeneous conditions throughout the reactor.

Stainless steel offers excellent corrosion resistance, durability, and ease of cleaning and sterilization. It also ensures a hygienic environment, reducing the risk of contamination.

A Stirred Tank Bioreactor provides good mixing and mass transfer capabilities. Compared to other designs, it offers more uniform conditions and is suitable for a wide range of processes.

The fermentation process is where microorganisms or cells grow and metabolize to produce desired products. The bioreactor provides the controlled environment for this process to occur efficiently.

The speed is typically controlled by a variable frequency drive or a similar mechanism that allows for precise adjustment based on the requirements of the specific process.

Yes, it can be adapted for both types of fermentation by adjusting parameters such as oxygen supply and agitation speed.

Regular inspection of the motor, bearings, and impeller for wear and tear is necessary. Lubrication of moving parts and calibration of the speed control system are also important.

This is usually achieved through jackets around the vessel through which a heating or cooling medium (like water or steam) flows, or by using internal heating/cooling coils.

Sterility is maintained through thorough cleaning and sterilization before use. This may involve autoclaving, chemical sterilization, or using steam-in-place systems.

The nature of the process, the type of organism or cells being used, the scale of production, and the required control over process parameters are some of the main factors.

pH can be regulated by adding acids or bases as needed. pH sensors monitor the conditions, and automated systems control the addition of the appropriate substances.
