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

The Sartorius Biostat B SU Univessel System Twin is a benchtop bioreactor controller designed for parallel control of two single-use bioreactor vessels, optimized for mammalian cell culture and bioprocess development. This advanced system supports precise control of temperature, agitation, and gas supply, incorporating specialized features essential for biotechnology applications such as bioprocess optimization, molecular diagnostics, and biomanufacturing workflows.

Key technical features include:

• Dual vessel control with a twin main control tower supporting independent operation of two Univessel SU single-use stirred tank bioreactors (working volume 0.6–2 L).
• Integrated 4-gas mixing system (Air, O₂, N₂, CO₂) using Thermal Mass Flow Controllers (TMFC) with ±1% full scale precision, enabling precise aeration and headspace control essential for suspension cell culture and process reproducibility.
• Direct drive agitation system powered by 200 W motors offering adjustable speed ranges up to 2000 rpm (for 1–10 L vessels) with 20–400 rpm specific to the 2 L single-use vessels, ensuring optimal mixing and shear conditions for fragile mammalian cells.
• External heating blankets providing temperature regulation up to 50 °C with 220 W heating capacity for single-use vessels, supporting controlled incubation for cell growth and protein expression studies.
• Multiple integrated peristaltic pumps (3 built-in Watson Marlow 114 fixed-speed pumps, 2 external Watson Marlow 120U speed-controlled pumps) for feed, base addition, and dosing, critical for automated media supply and pH regulation.
• Comprehensive digital sensor and interface connectivity, including support for weight sensors (vessel scales), inline biomass detection (BioPAT ViaMass), pH/redox, dissolved oxygen optical sensors, and analog signal inputs for extended bioprocess monitoring and control.
• Compact footprint (35×82.2×43 cm), 55 kg weight, and 120 V power supply make it suitable for laboratory-scale bioprocessing, seed train expansion, and parallel cultivation experiments in biotechnology research and development settings.

This system is widely adopted by biotech researchers focusing on live-cell imaging, recombinant protein production, gene editing process development, and synthetic biology applications where precise bioreactor control and single-use technology reduce contamination risk and increase experimental throughput. The comprehensive gas mixing capabilities and data interface options enable integration into advanced molecular diagnostics pipelines and bioprocess optimization for scale-up studies.

Note: Consumables such as single-use UniVessel bioreactor bags are not included and must be purchased separately. Optional customization includes autoclavable glass vessels, additional sensors, stirrer variants, and vessel scale options.

This pre-owned system is fully tested, calibrated, and serviced, with warranty support and remote training available, providing a reliable solution for laboratories requiring high-performance small-scale bioreactor control tailored to biotechnology and clinical diagnostics research.
