Sartorius Ambr 250 Modular 8-Vessel Benchtop Bioreactor System for Cell Culture and Fermentation

The Sartorius Ambr 250 Modular 8 Vessel Bioreactor System is a highly integrated benchtop platform engineered for parallel process development in *mammalian cell culture* and *fermentation*. It features eight independently controlled, disposable single-use vessels of 250 mL volume designed for scalable bioprocess workflows, including fed-batch and perfusion modeling critical in biopharmaceutical production pipelines.

Key technical specifications include:

• Bioreactor vessels: 350 mL total, 100-250 mL working volume with Easy-Connect single-use mammalian vessels
• Sensors: Fluorescence-based dissolved oxygen (DO) sensor and single-use pH electrode ensuring precise monitoring
• Operating ranges:
• Agitation speed: 100–4500 rpm
• Temperature control: 18–55°C with ±0.5°C accuracy
• pH control: range 2.0–8.5 with ±0.02 accuracy
• DO range: 0–200% air saturation
• Gas control: Configurable air/N₂, O₂, and CO₂ gas inlets with maximum gas flow 550 mL/min; exhaust gas O₂ and CO₂ monitoring for enhanced environmental control
• Integrated pumps per vessel: Five syringe pumps (0–20 mL/hr) and one peristaltic pump for accurate feeding and sampling, supporting complex bioprocess feeding strategies
• Additional features: Centralized touchscreen controller with camera, modular design with four bioreactor modules (two vessels each), recirculating chiller for post-culture cooling (6-8°C), and starter toolkits included
• Footprint: Compact dimensions (204 x 45.5 x 65 cm) suitable for space-efficient bioprocess development labs

This system supports *parallel bioreactor process optimization*, *media and feed optimization studies*, *clone screening and selection*, and *scale-up/down bioprocess studies*, making it essential for molecular biology and synthetic biology research workflows. It is widely adopted in *molecular diagnostics*, *bioprocessing*, and *biomanufacturing* applications where precise control of biological parameters and automated feeding protocols are critical.

The instrument has been thoroughly tested, serviced, and calibrated until July 2026 by Sartorius. It includes extended technical support and warranty, ensuring reliable performance for biotechnology research environments. Note that consumables such as single-use vessels are sold separately.

This system is ideal for researchers and biopharma professionals seeking scalable and automated cell culture and fermentation solutions that enhance productivity and reproducibility in complex *bioprocess development pipelines*.
