Sartorius Biostat B SU Univessel Twin Benchtop Bioreactor System for Cell Culture
Product Description
The Sartorius Biostat B SU Univessel System Twin is a benchtop bioreactor controller designed for advanced cell culture workflows, enabling parallel operation of two single-use stirred-tank vessels. This compact system supports both glass and single-use vessels with independent control over critical process parameters including pH, dissolved oxygen (DO), temperature, agitation speed, and gas flow.
Key technical specifications include:
- Twin control tower (Ref: BB-8821050) supporting two Univessel SU holders with integrated Sensolux sensors.
- Gas flow supply via 4 thermal mass flow controllers (±1% full scale) and 5 flow meters (±5%), enabling precise mixing of Air, O2, N2, and CO2 at max 1.5 barg.
- Independent sparger and overlay aeration lines for each vessel, delivering controlled gas flow rates optimized for bioprocess oxygenation and CO2 stripping.
- Built-in peristaltic pumps (three Watson Marlow 114) operating at fixed speeds for feed and base additions, essential for fed-batch and perfusion bioprocesses.
- Motor drive: 200 W direct-coupled stirrer motors, with agitation ranging from 20 to 2000 RPM, adjustable per vessel volume (e.g., 20–400 RPM for 2 L single-use).
- Temperature control via external 220W heating blankets, supporting accurate temperature regulation up to 50 °C.
- Digital connectivity: serial ports (RS-232 and RS-485) for integration of scales, biomass sensors (BioPAT ViaMass), analog signal inputs, and external peristaltic pumps for antifoam or acid/base feeds.
- Compact footprint (35×82.2×43 cm), weighing 55 kg, with 120 V power supply requirements for benchtop lab environments.
The system’s single-use Univessels support working volumes from 0.6 to 2 L with efficient mixing via dual 3-blade segment impellers at 30° angles and L-sparger aeration, minimizing contamination risks and reducing cleaning needs—critical for bioprocessing, molecular diagnostics, and synthetic biology applications.
This bioreactor system is widely used in biotechnology research, biopharmaceutical development, and clinical diagnostics, enabling rapid sterile setup and streamlined biomanufacturing workflows. Its precise gas flow control and scalable agitation range make it essential for gene editing, cell line development, and process optimization in small-scale biologics production.
Highlights:
- Supports parallel batch, fed-batch, and perfusion processes in two independent single-use vessels.
- Precise mass flow-controlled gas mixing for optimized cell culture aeration and pH balancing.
- Integrated control of agitation, temperature, and feeding pumps suited for mammalian and microbial cell cultures.
- Modular connectivity for sensor integration, facilitating enhanced process monitoring and automation.
- Includes remote setup support, training, and warranty suitable for research laboratories and bioprocess development facilities.
This system is a critical tool for research scientists, bioprocess engineers, and medical professionals focused on live-cell imaging, fluorescence analysis, and clinical bioprocess R&D, providing reliable performance in benchtop bioreactor control for cutting-edge biotechnology applications.
