Overview
The INFORS Techfors Cell Pilot-Scale Bioreactor System is an engineered platform for robust, reproducible, and scalable bioprocess development—from late-stage process optimization through clinical manufacturing support to early commercial production. Built upon over four decades of bioreactor design expertise and validated across hundreds of installations worldwide, the Techfors Cell system applies fundamental principles of fluid dynamics, mass transfer, and thermal management to ensure consistent oxygen transfer (kLa), homogenous mixing, and precise environmental control. Its modular architecture supports seamless transition from laboratory-scale data to pilot-scale performance, minimizing technical risk during technology transfer. The system operates under strict adherence to biopharmaceutical engineering standards, with structural integrity verified per ASME BPVC Section VIII Div. 1 and materials compliant with USP Class VI and FDA 21 CFR Part 211 requirements.
Key Features
- Safe-DDC Advanced Process Controller: A fully integrated, safety-certified (IEC 61508 SIL2) digital control unit enabling simultaneous monitoring and regulation of pH, dissolved oxygen (DO), temperature, agitation speed, gas flow rates (air/O2/N2/CO2), and foam level—each with configurable setpoints, PID tuning, and real-time trend logging.
- Flexible Agitation Architecture: Choice of top-driven or bottom-driven impeller configurations, compatible with Rushton turbines, marine propellers, or pitched-blade impellers; shafts constructed from electropolished ASTM A276 Type 316L stainless steel with dynamic balancing to ≤2.5 µm residual unbalance.
- Dual-Mechanical Seal Option: Available with ISO 21049-compliant dual mechanical seals incorporating barrier fluid monitoring and leak detection—critical for containment-sensitive mammalian or viral vector processes.
- Integrated CIP/SIP Capability: Fully automated cleaning-in-place and steam-in-place cycles with programmable temperature ramping (up to 135 °C), pressure hold (≥3.5 bar g), and conductivity-based rinse endpoint detection.
- Space-Efficient Engineering: Compact footprint achieved via vertical integration of sensors, valves, and tubing manifolds; standardized 200 mm centerline spacing enables alignment with cleanroom utility corridors and mobile skid integration.
- Material & Surface Compliance: All wetted parts fabricated from ASTM A240 316L stainless steel with Ra ≤ 0.4 µm electropolished finish; welds inspected per ASME B31.3 and documented with traceable WPS/PQR records.
Sample Compatibility & Compliance
The Techfors Cell system accommodates microbial (E. coli, yeast, bacillus), mammalian (CHO, HEK293), insect (Sf9), and stem cell suspension cultures—as well as microcarrier-based adherent systems. It meets core regulatory expectations for process validation: all critical parameters are logged with time-stamped, user-authenticated audit trails satisfying FDA 21 CFR Part 11 and EU Annex 11 requirements. Sensor calibration certificates (pH, DO, conductivity) follow ISO/IEC 17025-accredited protocols, and system qualification documentation (DQ/IQ/OQ/PQ) is provided per ISPE Baseline Guide Vol. 4. The vessel design conforms to EMA’s “Guideline on Development and Manufacture of Biological Medicinal Products” for scalability justification.
Software & Data Management
INFORS’ Labworldsoft® Bioprocess Suite serves as the native HMI and data historian, supporting multi-user role-based access control (RBAC), electronic signature workflows, and export to CSV, PDF, or OPC UA-compatible MES/SCADA environments. Raw sensor data is sampled at 1 Hz with 16-bit ADC resolution; historical datasets are stored in encrypted SQLite databases with automatic backup to network drives. Batch reports include metadata such as operator ID, calibration status, alarm history, and deviation annotations—enabling full traceability for internal audits or regulatory inspections.
Applications
- Clinical batch production of monoclonal antibodies, recombinant proteins, and viral vectors (AAV, lentivirus)
- Process characterization studies including design-of-experiments (DoE) for pH/DO/agitation interaction effects
- Scale-down model development for upstream process validation
- Fermentation optimization of industrial enzymes and organic acids
- Cell banking expansion under controlled shear and metabolic conditions
- Bioreactor training and operator qualification in cGMP environments
FAQ
What volume ranges does the Techfors Cell system support?
Standard configurations span 5 L to 500 L working volume; custom-engineered vessels up to 1,500 L are available with reinforced jacketing and enhanced agitation torque specifications.
Is the system compliant with FDA 21 CFR Part 11?
Yes—Labworldsoft® implements electronic signatures, audit trails, and data integrity controls aligned with Part 11 and EU Annex 11 requirements.
Can the Techfors Cell be integrated into an existing automation infrastructure?
It supports Modbus TCP, OPC UA, and Ethernet/IP protocols for bidirectional communication with DCS or MES platforms.
What validation documentation is included?
Full DQ/IQ/OQ documentation packages are supplied, including sensor calibration records, FAT/SAT protocols, and material compliance dossiers (EN 10204 3.1).
Are single-use options available for this platform?
While the Techfors Cell is a stainless-steel reusable system, INFORS offers parallel single-use solutions (e.g., Minifors 2, Multifors 2) for comparative studies and hybrid process strategies.
