Description
In biopharmaceutical processes, different cell types and culture scales demand varied stirring positions—top - stirring suits small - batch R&D, bottom - stirring boosts oxygen transfer for high - density culture, and side/multi - level stirring caters to shear - sensitive cells or large - volume mixing. Off - the - shelf bioreactor bags usually have fixed stirrer positions, failing to meet these diverse needs, and poor film quality or improper stirring can damage cells and reduce yields. Traditional rigid reactors have high validation costs and cross - contamination risks.
Our G - Type Disposable Bioreactor Bags with customizable stirrer positions, made of Renolit 9101 film, perfectly solve these problems.
The core highlight is the customizable stirrer position. You can choose top - mounted for easy installation and standard mixing , bottom - mounted for higher oxygen transfer, side - mounted for ultra - low shear (great for CAR - T cells), or multi - level dual - paddle for uniform mixing in large - volume 3D bags.
Every bag undergoes Gamma sterilization (25-40 kGy) and 100% helium integrity testing to eliminate micro - leaks and contamination risks. Produced in a Class C+A clean room, the bags meet ADCF, low E&L, and strict endotoxin standards, supporting regulatory submissions for biopharmaceuticals and ATMPs. Whether for small - batch R&D or large - scale commercial production, these G - type bags offer unmatched flexibility and reliable performance.
