Thermo Fisher CTS Rotea Counterflow Centrifugation System Unit 2 for Automated Cell Processing

The Thermo Fisher CTS Rotea Counterflow Centrifugation System Unit 2 is an advanced counterflow centrifuge designed for gentle and efficient cell processing workflows commonly used in cell therapy, molecular diagnostics, and biomanufacturing. This compact, closed-system device provides sterile, scalable solutions for cell washing, concentration, separation, and buffer exchange with minimal shear stress to preserve cell viability.

Key technical specifications include:

• Maximum centrifugal force: 3000 x g, optimized for efficient cell separation and concentration
• Centrifuge chamber volume: 10 mL, supporting cell counts from 5x10^7 to 5x10^9 per load
• Peristaltic pump flow rates:
• Standard kit: 5–110 mL/min
• Hi-Flow kit: 30–160 mL/min
• Output cell concentration range: 5x10^6 to 3x10^8 cells/mL
• Recommended input volume: 50 mL up to 20 L accommodates small-scale research to clinical bioprocessing
• Minimum output volume: 5 mL for concentrated cell product collection
• Max fluid density handled: 1.10 g/mL
• Weight: 20 kg (44 lb), enabling efficient lab space utilization

The system integrates essential components such as pinch valves, a peristaltic pump, and an onboard camera supporting process monitoring and control via proprietary software. This system supports automated, reproducible cell processing workflows used in biotechnology research, including gene editing applications, synthetic biology workflows, and cell therapy bioprocessing.

Its closed system design ensures sterility critical for clinical manufacturing environments. The unit excels in applications requiring gentle cell handling such as live-cell washing, cell enrichment, and buffer exchange for sensitive cell populations while maintaining high cell viability.
