Cytiva Xcellerex™ X-200 Single-Use Bioreactor

Overview

The Cytiva Xcellerex™ X-200 is a high-performance, single-use bioreactor engineered for scalable, cGMP-compliant mammalian cell culture processes. It operates on the principle of magnetically coupled bottom-driven agitation within a disposable polymeric bag, eliminating mechanical seals and shaft penetrations to ensure sterility assurance and reduce contamination risk. The system integrates advanced fluid dynamics design—including optimized impeller geometry, multi-port gas sparging, and strategically placed baffles—to achieve high oxygen transfer rates (k_La > 15 h⁻¹) and efficient CO₂ stripping while maintaining low shear stress (< 0.1 Pa), critical for sensitive suspension and adherent cell lines. Designed for seamless transition from process development through clinical and commercial manufacturing, the X-200 supports volumes from 50 L to 200 L working volume and is validated for use in both pilot-scale facilities and full-scale cGMP production suites.

Key Features

• Magnetically coupled bottom-drive agitation enabling minimal minimum working volume (as low as 20% of nominal capacity) and reduced footprint of disposable bags
• CFD-optimized tank geometry with integrated baffles and re-engineered gas distribution manifold for enhanced mass transfer efficiency
• Modular, standardized bag platform with four pre-qualified configurations: batch, fed-batch, perfusion, and high-density inoculum expansion
• Figurate™ automation system built on Rockwell Automation’s PlantPAx® DCS architecture, supporting recipe-based control, audit trails, and electronic batch record (EBR) integration
• Optimized cable management and hinged tank door design for rapid bag installation, visual inspection, and maintenance access
• Wide power input range enabled by CFD-guided drive placement, facilitating robust scale-up predictability from lab to manufacturing

Sample Compatibility & Compliance

The Xcellerex™ X-200 accommodates a broad spectrum of bioprocess-relevant cell types, including CHO, HEK293, CAP-T, and hybridoma lines—both suspension and microcarrier-adapted formats. All disposable components are manufactured under ISO 13485-certified conditions and comply with USP and for plastic materials. The system meets FDA 21 CFR Part 11 requirements for electronic records and signatures when configured with Figurate™ audit trail and user access controls. It supports GLP/GMP-aligned validation protocols per ASTM E2500 and ICH Q5D, and is compatible with industry-standard cleaning-in-place (CIP) and sterilization-in-place (SIP) verification practices for reusable hardware modules.

Software & Data Management

The Figurate™ automation platform provides deterministic, deterministic real-time control of pH, DO, temperature, agitation speed, gas flow rates, and feed/perfusion pumps. All process data—including raw sensor inputs, calculated derived parameters (e.g., OUR, CER, RQ), and alarm/event logs—are time-stamped and stored in a relational database with configurable retention policies. Data export complies with ASAM ATX and ISA-88/ISA-95 standards, enabling direct integration with MES, LIMS, and PAT frameworks. Full traceability is ensured via immutable audit trails, role-based permissions, and digital signature support aligned with Annex 11 and ALCOA+ principles.

Applications

• Monoclonal antibody (mAb) and bispecific antibody production in fed-batch and perfusion modes
• Viral vector manufacturing (AAV, lentivirus) requiring low-shear environments and precise DO/pH control
• Cell therapy expansion workflows, including T-cell and NK-cell culture under GMP conditions
• Process characterization and comparability studies across scales using Bioreactor Scaler™ modeling tools
• Accelerated tech transfer between development labs, CMOs, and internal manufacturing sites

FAQ

What regulatory documentation is available for the Xcellerex™ X-200 system?

Cytiva provides comprehensive qualification packages including DQ/IQ/OQ documentation templates, material compliance certificates (USP Class VI, REACH, RoHS), and third-party validation reports for key unit operations.
Can the X-200 be integrated into an existing PlantPAx® DCS environment?

Yes—the Figurate™ controller supports native Ethernet/IP communication and OPC UA server functionality for bidirectional integration with legacy or greenfield DCS installations.
Is the system qualified for perfusion applications at 200 L scale?

Yes—validated perfusion operation up to 200 L working volume has been demonstrated with cell densities exceeding 30 × 10⁶ cells/mL and viabilities >95% over 14-day runs.
How does OptiRun™ service reduce operational risk?

OptiRun™ includes predictive maintenance analytics, remote diagnostics, SLA-backed response times (<4 hours for critical alarms), and globally coordinated engineer dispatch—minimizing unplanned downtime and supporting continuous manufacturing readiness.
