Sartorius Stedim Biostat B Twin Bioreactor System with Dual 2L Autoclavable Single-Wall Glass Vessels
Product Description
The Sartorius Stedim Biostat B Twin Bioreactor is a compact, dual-unit bioprocess system designed for parallel mammalian and insect cell culture applications at small scale, supporting working volumes from 0.4 to 2 liters in autoclavable single-wall glass vessels. This system is equipped with advanced modules for precise pH, dissolved oxygen (DO), temperature, agitation, and multigas mixing, essential for controlled and reproducible bioprocessing workflows in biotechnology research and development.
Key Technical Features:
- Dual independent control towers allow simultaneous regulation of two culture vessels for process optimization and scale-up studies.
- Vessels: Two 2 L single-wall glass vessels with 3-blade pitched impeller, ring sparger, overlay aeration, and integrated exhaust condensers with vapor condensation capability.
- Agitation: Direct-drive motor (200 W) providing agitation speed from 20–2000 RPM, ensuring gentle mixing, critical for shear-sensitive cell lines.
- Gas Mixing: Precise 4-gas mixing system (Air, O2, N2, CO2) with thermal mass flow controllers (TMFCs) and rotameters ensuring accurate gas flow control up to 1.5 barg for physiologically relevant culture environments.
- Sensors: Includes pH, DO (optical), and temperature sensors with high accuracy (±0.1 °C for temperature, ±1% full scale for gases), essential for real-time monitoring and control in molecular diagnostics and bioprocess optimization.
- Temperature Control: External heating blankets combined with cooling finger modules maintain culture temperatures from 8 °C above cooling-water inlet temperature up to 60 °C.
- Peristaltic Pumps: Built-in Watson Marlow fixed-speed pumps for acid/base addition and media feed enable automated pH control and nutrient delivery, aiding fed-batch and batch cultivation processes.
- Interface and Connectivity: Multiple digital ports (RS-232, M12 plugs, VP8 plugs) for sensor inputs and external signal control enhance integration into laboratory automation and process analytical technologies.
- Dimensions & Power: Compact footprint (35 × 82.2 × 43 cm) and 120 V power requirements facilitate installation in research labs focused on synthetic biology and biomanufacturing.
Applications:
- Small-scale controlled cultivation of mammalian and insect cells.
- Seed train development, upstream process optimization, and media/feed strategy evaluation.
- Critical for cell line development, metabolic and growth kinetics studies.
- Widely adopted in molecular biology, gene editing workflows, and biologics production pathways.
This bioreactor system supports reproducible and scalable culture conditions, crucial for biotechnology pipelines including molecular diagnostics, synthetic biology research, and biopharmaceutical manufacturing. The inclusion of remote setup, training, and a 120-day warranty ensures reliable operation and post-sale support for researchers and process engineers.
This advanced twin bioreactor setup combines precise environmental control with flexible configuration options to meet evolving bioprocessing needs in biomedicine and industrial biotechnology environments.
