Sartorius Biostat RM 20/50 Benchtop Single-use Wave Bioreactor with Rocking Control
Product Description
The Sartorius Biostat RM 20/50 is a sophisticated benchtop single-use wave bioreactor designed for small-scale bioprocessing and process development in biotechnology and molecular diagnostics. It employs a rocking platform that generates gentle wave-induced mixing, promoting low-shear, bubble-free aerobic culture conditions ideal for sensitive cell lines and suspension cultures.
Key technical specifications include:
- Working volume: 5 L minimum, 25 L maximum (total vessel capacity 50 L)
- Rocker speed: Adjustable from 8 to 42 rocks per minute
- Rocker angle: Programmable between 4° and 10° with ±0.3° precision
- Temperature control: Ambient to 40°C, managed via integrated heating pads and PT100 probes (2 probes included)
- Gas flow control: Air, oxygen, and nitrogen supplied with mass flow regulation (0–500 mL/min per single-use bag CO2, 0.2–10 L/min total flow) and fixed CO2 range from 0 to 15%
- Process monitoring: pH range 6.5–8.5, dissolved oxygen (DO) range 0–100%, compatible with single-use pH and DO sensors
- Data interface: Color touchscreen display on the Cultibag RM controller with RS232 communication for PC integration, enabling detailed process control, trend analysis, and simultaneous operation of two culture bags with independent settings
- Physical footprint: Base footprint 43×26×22 inches; control tower 15×25×29 inches; weight approx. 200 lbs
- Power requirements: 100–240 V, 50/60 Hz, 600 W
This bioreactor is essential for bioprocessing workflows in biopharmaceutical production, gene editing research, and synthetic biology applications, where aseptic, single-use technology reduces contamination risk and eliminates the need for clean-in-place (CIP) and steam-in-place (SIP) protocols. The wave mixing technology ensures homogeneous culture conditions, making this reactor widely adopted in both academic and industrial settings for cell expansion, fermentation, and biomanufacturing efforts.
Included accessories feature the Cultibag RM touchscreen controller, lid with integrated heater pads and sensors, communication cables, and standard power cords, offering turnkey operation immediately upon installation.
This Sartorius Biostat RM 20/50 wave bioreactor combines precise environmental control, flexible gas delivery, and reliable data acquisition—making it a critical tool for lab-scale bioprocess development, cell culture optimization, and biotechnology research.
