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

The Sartorius Biostat B SU Univessel Twin System is a versatile benchtop bioreactor designed for parallel cell culture workflows in biotechnology, molecular diagnostics, and bioprocess development. This system supports both single-use (SU) Univessel stirred-tank vessels and glass vessels, enabling flexible deployment in batch, fed-batch, or perfusion processes at laboratory scale.

_Key technical features include:_

• Twin independent vessel control for simultaneous culture monitoring and regulation
• Integrated pH, dissolved oxygen (DO), temperature, and agitation control per vessel
• Advanced gas supply system with four mass flow controllers (MFCs) enabling precise mixing of Air, O2, N2, and CO2 for sparger and overlay aeration
• Working volume range of 0.6 to 2 L per vessel with 200 W motor drive offering 20–2000 RPM agitation (20–400 RPM for 2 L SU vessels)
• External heating blankets with temperature control up to 50°C and rapid sterile changeover via single-use vessels
• Controller features 3 built-in Watson Marlow peristaltic pumps for feeds with fixed speeds, and support for additional external pumps
• Digital connectivity includes ports for biomass sensors (BioPAT ViaMass), substrate/balance sensors, temperature probes (Pt100), and analog signal integration
• Dimensions: 35×82.2×43 cm, net weight 55 kg, power requirement 120 V, 12 A max

This system enhances cell culture bioprocessing by streamlining sterile setup and reducing cleaning demands through disposable SU vessel technology, critical for synthetic biology, gene editing, and biomanufacturing workflows. It is widely adopted in small-scale biopharmaceutical production pipelines and academic research labs focusing on mammalian and microbial cell culture.

Typical applications:

• Parallel cultivation for cell line development and process optimization
• Small-scale biologics production and biotechnology research
• Development of molecular diagnostics and tissue engineering

Customization options include temperature, pH, and DO sensors, stirrer variations, vessel scale monitoring, and exhaust gas analyzers, making it suitable for tailored bioprocess control demands.

This pre-owned system is fully serviced, calibrated, and includes a 120-day US warranty, with optional remote setup and training. It is essential for laboratories requiring precise, scalable control of cell culture parameters within compact benchtop footprint environments.
