Cobetter Lifecask™ RW Single-Use Bioreactor Bags are specially designed for a rocking mode bioreactor. It is sterilized by gamma irradiation and packaged in double PE bag to avoid cross-contamination. The bioreactor bags are manufactured with our self-produced Lifemeta™ KA film to ensure a good mechanical performance as well as biocompatibility.

Lifecask™ RW Single-Use Bioreactor bags can be widely applied to multiple upstream process of bio-pharmaceuticals such as antibody, vaccine and CGT. Apart from the basic bag configuration, we launched RW PRO features integrated pH and DO optical sensors, and RW Perfusion with an integrated retention membrane to satisfy multiple culture modes such as seed train expansion, fed-batch or perfusion processes. What’s more, fabric carriers or microcarriers can also be applied to the bags for adherent cell culture.

Applications

  • Suspension Cell Culture: CHO, HEK293, BHK21, Hybridoma, SF9
  • Suspension cell perfusion culture (Cell Retention Membrane/ Hollow Fiber)
  • Adherent cell culture: HEK 293, Vero, etc.

Lifemeta™ KA film

Cobetter Lifecask™ RW Single-use Bioreactor bags use our self-produced Lifemeta™ KA film for the bag body. Lifemeta™ KA film is a five-layer co-extruded film manufactured to meet the high mechanical strength required by a rocking-mode bioreactor. Lifemeta™ KA film is manufactured by a blowing film technology and has a clean inner layer made by ULDPE. The outer layer is made by HDPE, which allows the film to have good environmental stress resistance, tensile strength and chemical tolerance.

Lifemeta™ KA film has been tested and validated to have the features of a low E&L profile and good biocompatibility. It has no potential risk of introduction of impurities and could be applied throughout the whole process of bio-pharmaceuticals. Till now, it has been used for media or buffer preparation and storage bags, cell culture bioreactor bags and filling bags.

Systematic Product Validation

Cobetter Application & Validation Laboratory (AVL) center has been accredited by China National Accreditation Service for Conformity Assessment (CNAS). Cobetter LifecaskTM RW single-use bioreactor bag has been fully validated and well tested. The associated documents such as validation guide, E&L report and application notes are available.

Flexible Customization & Reliable Supply Chain

Cobetter offers custom solutions including customized bag dimensions or customized tubings & assemblies configuration according to customers’ bioreactor and upstream cell culture process.

Cobetter takes full risk assessment on raw material, including inventory management and key suppliers management. So far, Cobetter has 11 production lines for bags, tubings and assemblies in ISO Class 7 cleanroom, ensuring a stable product supply and a competitive lead time of our products.
