Description
In biopharmaceutical upstream processes, bottom-stirred bioreactors are critical for uniform mixing, high oxygen transfer, and low shear—yet off-the-shelf bags often fail to match custom hardware or sensitive cell needs, while poor seals/sterility risk batch failure. Traditional stainless steel systems demand costly CIP/SIP validation and risk cross-contamination.
Our Type A Disposable Bioreactor Bags with bottom-mounted stirrers, built with Renolit 9101 film, solve these issues with tailored performance and reliable compliance.
The defining bottom-stirrer design delivers superior mixing: marine impellers for suspension cells (low shear, even for shear-sensitive CAR-T), turbine impellers for high-density microbial culture (enhanced kLa), or anchor impellers for microcarrier-based adherent cells to prevent sedimentation. Double-welded seams + port connections, plus 100% helium integrity testing, eliminate micro-leaks during agitation.
Every bag is Gamma-sterilized (25-40 kGy) and pre-sterilized in double-layer packaging, cutting setup time by 40% vs. stainless steel systems.
Customization is fully supported: select 2D (5L-50L, R&D) or 3D (100L-2000L, commercial) bag types; tailor stirrer geometry, tubing ID/length, and connector types to fit mainstream hardware (Thermo, Cytiva, Sartorius). Manufactured in a Class C+A clean room, the bags meet ADCF, low E&L, and endotoxin <0.25 EU/mL standards, supporting regulatory submissions for ATMPs and biopharmaceuticals. Whether for CHO antibody production, CAR-T cell expansion,, these Type A bags deliver consistent mixing, leak-proof reliability, and plug-and-play integration.
