Scalable Single-Use Bioreactor | 50L-2000L SUB Cell Culture System

Engineered for biopharmaceutical pilot scaling and cGMP commercial manufacturing, this fully scalable single-use bioreactor platform delivers automated process consistency across suspension cultures and adherent microcarrier applications. Optimized for mammalian cell lines (including CHO and HEK293) as well as insect cell expressions, the platform provides predictable hydrodynamic performance and linear scalability across vessel sizes spanning 50 L, 200 L, 500 L, 1000 L, and 2000 L.

Vessel Architecture and 9-Layer Coextrusion Bio-Container Barrier The vessel hardware combines an ergonomic 304 stainless steel containment shell with pre-sterilized single-use bioprocess bags. The disposable contact layer utilizes a specialized 9-layer coextruded high-barrier polymer film (330 μm total thickness) comprising outer LLDPE, structural PA, gas-impermeable EVOH, secondary PA, and fluid-contact ULDPE. Compliant with USP, EP, and ChP pharmacopeial monographs, this composite structure provides puncture resistance while blocking oxygen, carbon dioxide, and water vapor ingress. Mixing is governed by a heavy-duty servo agitation drive delivering speed stability within ±0.5 rpm, breaking up sparger micro-bubbles into uniform dissolved oxygen fields while maintaining low shear stress.

Dual-Sensing Metrology and Automated Cascade Aeration The instrument integrates dual pH and dissolved oxygen tracking: operators can configure either reusable digital smart probes or non-invasive pre-installed single-use optical fiber sensors. Dissolved oxygen is regulated within ±3% air saturation via a multi-gas cascade coupling agitation rate with sparger mass flow controllers (O₂, N₂, CO₂, and Air) and an overlay air MFC. Closed-loop pH is automatically managed through automated base addition pumps and CO₂ gas metering. To avoid vent filter wetting and culture bag pressurization, the exhaust assembly includes an automated heating jacket operating from room temperature to 60°C (±2°C precision) along with a sensitive -10 to +10 kPa differential pressure sensor.

Honeycomb Thermal Jacket and Digital Metrology Integration Thermal regulation relies on a high-efficiency honeycomb fluid jacket equipped with sanitary TC50 tri-clamp connection ports and external polyurethane foam insulation. The jacket links directly to dedicated Temperature Control Units (TCU), allowing vessel fluid temperature adjustment from ambient up to 42°C (±0.2°C accuracy) directly through the primary human-machine interface without separate chiller manipulation. Liquid mass is tracked via C3-class stainless steel load cells featuring anti-tipping, overload safeguards, and direct digital PLC communication to eliminate analog signal attenuation.

GMP and 21 CFR Part 11 Data Governance Automation is executed by an industrial IPC running an advanced supervisory control and data acquisition (SCADA) platform. Featuring three-tier role-based access management, electronic signatures, secure audit trails, customizable standard operational recipes, and exportable process trend curves, the software complies with FDA 21 CFR Part 11 and cGMP data integrity requirements.

Technical Specifications

Frequently Asked Questions (FAQ)

1. What operational working volume range is supported across the series?

The product series spans total working capacities from 50 L up to 2000 L, with turndown flexibility allowing minimum inoculations as low as 22 L in the 50 L model and 400 L in the 2000 L model.

2. Which cell lines and cultivation modalities are suitable for this equipment?

The platform is optimized for mammalian cell cultures (CHO, HEK293), insect cell platforms, suspension fermentations, and adherent cell expansion using microcarriers.

3. What is the material composition of the single-use culture contact film?

The bio-container utilizes a medical-grade 9-layer coextruded polymer film (330 μm thick) containing LLDPE, PA, EVOH, and ULDPE fluid-contact layers meeting USP, EP, and ChP standards.

4. How does the system measure and control dissolved oxygen (DO)?

DO is measured using either traditional electrochemical probes or non-invasive optical sensors, linking into a cascade loop that modulates agitation speed alongside Air, O₂, and N₂ mass flow controllers.

5. Can the bioreactor accommodate both conventional and single-use optic pH sensors?

Yes, the system supports both insertion-style digital smart pH electrodes (pH 2–12, ±0.05 control) and pre-sterilized single-use optical fiber sensors (pH 5.5–8.5, ±0.1 control).

6. How is vessel heating and cooling managed during active cell culture?

The vessel utilizes a stainless steel honeycomb jacket paired with external polyurethane foam insulation, controlled through a dedicated TCU directly from the main IPC interface.

7. How does the exhaust gas heating mechanism protect against bag over-pressurization?

The exhaust filter includes an automated electric heating collar (ambient to 60°C) to prevent moisture condensation and filter fouling, coupled with a -10 to +10 kPa pressure sensor.

8. What features ensure regulatory data integrity for commercial GMP production?

The SCADA architecture complies with FDA 21 CFR Part 11, incorporating three-level permission hierarchies, electronic signatures, time-stamped audit trails, and automated batch reporting.

9. How are liquid mass and feed additions monitored by the system?

The reactor base integrates C3-grade stainless steel load cells featuring anti-tipping and overload protection, communicating digitally with the PLC to prevent analog signal loss.

10. What gas lines are regulated by the automated mass flow controllers (MFC)?

The gas manifold includes 5 dedicated mass flow controllers: one overlay air line, plus sparger lines for Air, pure Oxygen, Carbon Dioxide, and Nitrogen.

11. What electrical supply is needed to power the main control console?

The control cabinet operates on a standard single-phase AC 220V ± 10%, 10A, 50 Hz power connection with a total operational consumption of 1.5 kW.

12. How does the software simplify repetitive batch processing?

The SCADA software includes an integrated recipe manager where validated operational parameters can be stored and recalled, reducing manual configuration errors and batch variability.
