Sartorius Biostat B-DCU 4-Fold Single-Use Cell Culture Bioreactor System with Univessel SU Vessels

The Sartorius Biostat B-DCU 4-Fold Cell Culture Univessel SU Bioreactor System is a modular, parallel single-use bioreactor setup designed for advanced bioprocessing and cell culture applications in biotechnology and molecular diagnostics. It supports four independent bioreactor stations, each equipped for precise control of critical culture parameters.

• Bioreactor stations: Four independent units with Univessel SU single-use vessels (consumables not included) allowing working volumes of 0.6 to 2 L, featuring dual 3-blade segment impellers (30° angled) for optimized mixing and L-sparger aeration suited for mammalian cell culture.
• Controller & Gas Mixing: Integrated BioPat DCU Tower controls gas supply via 5 thermal mass flow controllers (TMFCs) with ±0.3% FS accuracy and additive 5-gas aeration modules (Air, O2, N2, CO2) tailored for bioreactor gas flow rates (e.g., overlay air flow up to 300 ccm).
• Agitation System: 200 W direct-coupled motor drives with adjustable speeds from 20 to 2000 RPM (2L vessels run 20–400 RPM), ensuring shear-sensitive culture conditions.
• Temperature Control: External heating blankets provide temperature stability up to 50°C with 185 W power rating, critical for reproducible bioprocess temperature management.
• Integrated Peristaltic Pumps: Each controller includes three Watson Marlow 114 Easy Load peristaltic pumps supporting rotary speed ranges from 5 to 150 rpm for substrate feeding and media additions.
• Sensor Connectivity: Multiple digital ports enable integration with Pt-100 temperature sensors, pressure sensors, analog/digital external inputs (0–10 V, 4–20 mA), optical sensors, viable biomass sensors (BioPAT® Viamass), balances, and external pumps, facilitating comprehensive process monitoring and control.
• Communications: Ethernet and industry-standard fieldbus (Modbus, OPC) allow centralized process data acquisition and automation integration, supporting bioprocess development and scale-down model validation.
• Physical & Power Specs: Compact footprint with dimensions 360×768×432 mm, weighing 45 kg, powered by 120 V, 60 Hz supply, maximum 12 A consumption ensuring compatibility with standard lab electrical infrastructure.

This system is ideal for parallel cell line development, batch and fed-batch cultivation, small-scale upstream process optimization, and critical biomanufacturing workflows. Its single-use design minimizes contamination risk and cleanup time, supporting efficient bioprocessing in biomedical engineering and synthetic biology research.

Overall, the Sartorius Biostat B-DCU system is widely adopted in molecular diagnostics, gene editing, and bioprocess development pipelines, offering reliable control of pH, dissolved oxygen (DO), temperature, and agitation essential for robust cell culture and biopharmaceutical production.
