Sartorius Biostat B SU Univessel Twin Benchtop Bioreactor Controller for Cell Culture

The Sartorius Biostat B SU Univessel Twin System is a benchtop bioreactor controller designed for parallel cell culture bioprocess development and small-scale production of biologics. This twin-vessel system supports both single-use Univessel SU stirred tank vessels and glass vessels, offering flexible usage essential for modern biotechnology workflows including molecular diagnostics and bioprocess optimization.

Key features include:

• Twin independent control towers (Ref.: BB-8821050) for simultaneous management of two culture vessels.
• Precise gas flow control with 4 Thermal Mass Flow Controllers (±1% full scale accuracy) and 5 flow meters (±5% accuracy), enabling 4-gas mixing (Air, O₂, N₂, CO₂) for advanced aeration strategies via sparger and overlay.
• Built-in peristaltic pumps (3 Watson Marlow 114, fixed speed) for substrate feed and base addition, supporting batch, fed-batch, and perfusion processes.
• Motor drive with 200 W direct coupling agitation motor, speed range 20–2000 RPM (20–400 RPM for 2L SU vessels), optimized for effective mixing with dual 3-blade segment impellers.
• Temperature control via external heating blankets regulated up to 50 °C with 220W heating capacity, ensuring stable vessel environments critical for cell viability and productivity.
• Multiple digital I/O ports supporting integration of pH, dissolved oxygen (DO), temperature sensors, BioPAT ViaMass biomass sensor, vessel weighing scales, and analog signals, facilitating comprehensive process monitoring and control.
• Compact dimensions (35×82.2×43 cm) and power supply of 120 V/60 Hz, suitable for laboratory benchtop environments.

This system is particularly relevant for biotechnology fields such as synthetic biology, biopharmaceutical production pipelines, and small-scale biomanufacturing applications. The use of single-use vessels accelerates sterile setup and reduces cleaning demands, aligning with goals of streamlined bioprocess workflows and cost-effective operation in molecular cloning and cell line development.

Included equipment: twin control tower, dual Univessel SU holders with Sensolux connection cables, agitation motors, 220W heating blankets, 7W filter heaters, pressure relief units, temperature sensors, and cable assemblies. Consumables, such as single-use vessels, are sold separately.

The Sartorius Biostat B is tested and serviced to ensure full functionality, including calibration of mass flow meters, pump operation, sensor accuracy, gas-mixing performance, and heating elements. The system comes with a 120-day U.S. warranty and 30-day international warranty, with options for remote setup training and installation consultation.

This benchtop bioreactor system is essential for research professionals conducting parallel cell culture experiments, process optimization, and bioprocess development needing precise control of pH, dissolved oxygen, temperature, agitation, and gas flow. Its twin-vessel design and single-use compatibility make it popular among molecular biology and biotechnology researchers for scalable cell culture and bioprocessing applications.
