Sintered Stainless Steel Sparger For Bioreactor Systems Diffusion Stone

Sintered Stainless Steel Sparger For Bioreactor Systems Diffusion Stone

In bioreactor systems, achieving optimal mass transfer of gases such as oxygen or carbon dioxide can be challenging. This is particularly true for oxygen, which is poorly soluble in water and even less so in cell culture and fermentation broths. While agitation is commonly used to mix nutrients and ensure homogeneity of the cell culture or fermentation, there are limits to agitation speed due to high power consumption and potential damage to organisms resulting from excessive tip speed.

Agitation alone is insufficient for achieving adequate mass transfer. However, by incorporating a TOPTITECH porous metal sparger, mass transfer rates can be significantly increased in this type of equipment. Optimal mass transfer rates can be accomplished by introducing gases into stirred or unstirred reactor vessels via millions of small bubbles, which expands the gas-to-liquid contact surfaces.

Sintered sparger stainless steel is a specialized material commonly used as a gas diffuser in bioreactor systems. This material is made by sintering stainless steel particles to create a highly porous structure with uniform pore size, allowing for efficient gas distribution in bioreactors.

Parameter

Pore size: 0.2-100 microns

Dia: 5-300mm

Length: 10-1000mm

Porosity: 30-50%

Operating temperature: up to 600°C

Maximum pressure: up to 10 bar

Feature

Uniform pore size distribution: The sintering process ensures a uniform pore size distribution, which allows for efficient gas distribution and minimizes pressure drop in bioreactor systems.

High mechanical strength: Sintered sparger stainless steel has high mechanical strength and can withstand harsh operating conditions, making it ideal for use in a variety of industrial and scientific applications.

Chemical resistance: Stainless steel is highly resistant to corrosion and can withstand exposure to a range of chemicals, making sintered sparger stainless steel an ideal material for use in bioreactor systems.

High temperature resistance: Sintered sparger stainless steel can withstand high temperatures up to 600°C, making it suitable for use in high-temperature bioreactor systems.
