Applikon 2-3L Bioreactor Baffle - M6 mount

Applikon Bioreactor Baffle Assembly – 2-3L, M6 Mount

The Applikon 2-3L Bioreactor Baffle is a critical structural component engineered to enhance mixing efficiency and gas-liquid mass transfer within 2-liter and 3-liter laboratory-scale glass bioreactors. Machined from premium 316L stainless steel, this baffle is designed to be suspended directly into the culture medium from the bioreactor headplate via an M6 threaded port. By physically disrupting the circular flow of liquid generated by the rotating impeller, the baffle prevents deep vortex formation and promotes chaotic axial and radial mixing. This action dramatically improves oxygen transfer rates and ensures a homogeneous suspension of nutrients and cells, making it an indispensable part for high-density microbial fermentation and mammalian cell culture.

Technical Performance and Design

• Vortex Prevention: Converts the swirling, laminar flow of an unbaffled vessel into turbulent flow, preventing the culture fluid from climbing the vessel walls and burying the impeller in a central air pocket.

• 316L Stainless Steel: Constructed from pharmaceutical-grade 316L stainless steel and electropolished to a surface finish of 20Ra or better, ensuring excellent corrosion resistance and preventing biofilm adhesion.

• M6 Headplate Mount: The top stem features a standard M6 thread, allowing it to seamlessly screw into designated M6 ports on Applikon, Broadley-James, or compatible 2-liter and 3-liter bioreactor headplates.

• Sterilization Compatibility: Fully autoclavable and capable of withstanding repeated thermal cycling and strict sterilization procedures without degrading or warping.

Product Specifications

• Vessel Compatibility: 2L and 3L Glass Bioreactors

• Mount Type: M6 Thread

• Material: 316L Stainless Steel

• Surface Finish: Electropolished (20Ra or better)

Key Benefits & Applications

• High-Density Fermentation: Absolutely critical for bacterial or yeast cultures that require high agitation speeds (RPM) and massive dissolved oxygen demands.

• Homogeneous Nutrient Distribution: Eliminates dead zones inside the bioreactor, ensuring that all cells are exposed to uniform pH, temperature, and nutrient concentrations.

• Easy Maintenance: The smooth, mirror-like electropolished surface is easily cleaned during standard wash procedures and resists chemical pitting.

• Universal Retrofit: Functions as a direct drop-in replacement for worn or bent baffles in existing standard benchtop bioreactor fleets.
