Mott Porous Metal Micro Sparger Tips for Bench-Top Laboratory Bioreactors and Fermentors Specifications Materials of Construction: Porous Media Grades: M5 thread with O-ring grooves, 10-32 UNF threads, hose barb, NPT threads and butt weld ends available. Advantages of Mott Porous Metal Micro Spargers Due to the low solubility of oxygen in many cell culture mediums, optimizing this critical nutrient can be difficult. Maximizing the surface area between the media and the aeration bubble can improve the mass transfer rates of oxygen or carbon dioxide significantly. A widely accepted method of maximizing the surface area is using a Mott porous metal micro sparger. These micro spargers can greatly reduce the size of the aeration gas bubbles which will increase the amount of surface area for a given volume of gas. It is not unusual to effectively increase mass transfer rates by 100% to 400% over standard drilled pipe or single opening dip tubes. Optimal Pore Sizes for Optimal Mass Transfer Mott Corporation offers a wide variety of porous metal sparger tips for laboratory and pilot scale bioreactors and fermentors. With media grades ranging from 2 µm to 15 µm, Mott porous spargers offer the flexibility to generate bubble sizes which are optimal for your specific media, organism and mass transfer requirements. Whether your application calls for optimal oxygen mass transfer or oxygen or CO2 stripping, there is a Mott micro sparger tip for your needs. Sparger tips come with a M5 thread, 10-32 UNF thread, or weld stubs. For Pilot Scale and Larger For larger bioreactors and fermentors, Mott’s Quick Change Sparger tips allow for quick and easy removal and replacement of the sparger in pilot or production scale reactors. See the Mott Brochure HPBIOSPARG for Quick Change Sparger System for Bioreactors and Fermentors.
