Separator system for cell harvesting optimized for biopharma and biotech

  • Efficient and gentle separation resulting in high yield
  • Low lysis and high filterability, reducing costs of downstream filtration
  • Enables continuous removal of solids up to 40% concentration in feed
  • Accurate scalability from pilot scale to large-scale production
  • Fully automated and flexible for process variations

The complex and delicate nature of cells requires careful handling to secure high yields and facilitate downstream filtering. Through continuous and highly efficient separation, MB 20 and MB 20 Bactofuge centrifuges bring improved productivity to biopharma applications at pilot scale.

The MB range of centrifuges incorporates unique Alfa Laval technologies, like Hermetic Design™ for enhanced product handling in various separation applications, and Bactofuge®, facilitating gentle but speedy processing of high-solids broths with continuous discharge of a highly concentrated solids phase. With these innovations, the MB centrifuges add profitability and offers unmatched scalability for biotech and biopharmaceutical pilot projects and small-scale production.
