Beckman Avanti JA-20.1 Fixed Angle Rotor 20,000 rpm for JXN-26 and J-26 Series Centrifuges

The Beckman Avanti JA-20.1 Fixed Angle Rotor is a high-performance centrifuge rotor designed specifically for Avanti JXN-26, J-26S, J-E, and JXN-30 centrifuge models. Constructed from durable anodized aluminum and featuring a biosafety lid with Buna N O-rings, it combines robust material engineering with secure sealing for safe biosample processing.

Key technical specifications include:

• Rotor type: Fixed-angle with a 23° inclination angle
• Capacity: 32 tubes of 15 mL volume arranged in two concentric rows
• Maximum Speed: 20,000 rpm
• Maximum Relative Centrifugal Force (RCF): 51,500 × g (outer row), 43,900 × g (inner row)
• k-Factor: 371, indicating efficient sedimentation performance
• Mounting: Uses two drive-hub pins for stable and secure rotor fixation
• Acceleration/Deceleration: Approximately 1.5 minutes to reach max speed; deceleration in 2.5 minutes

This rotor is engineered for a broad range of biotechnology and molecular biology applications, including:

• Pelletization of cells and bacteria from culture media
• Separation and isolation of subcellular organelles for cell biology research
• Harvesting precipitated proteins fundamental in molecular diagnostics workflows
• Clarification of lysates to prepare samples for downstream biochemical analysis

The JA-20.1 rotor undergoes rigorous performance and safety verification cycles to ensure stable, vibration-free operation without compromising centrifuge integrity. Its high G-force capability and capacity make it essential for bioprocessing applications requiring large-volume, high-speed sedimentation.

Due to its compatibility with several Beckman Avanti centrifuge series, the rotor is widely adopted in clinical diagnostics, synthetic biology, and biomanufacturing pipelines where reliable, reproducible centrifugation is critical. The rotor’s optimized k-factor and high maximum speed enable efficient separation protocols, helping streamline workflows in gene editing research and biopharmaceutical production.

Users receive a rotor with a new lid o-ring included and a comprehensive warranty supporting technical and after-sales service. Pre-owned units are tested extensively by expert service teams to certify full functionality and long service life, offering a cost-effective option without compromising performance or safety.

This rotor represents a vital centrifugation accessory within benchtop centrifuge configurations, supporting diverse applications in neuroscience, cell imaging, and biotechnology labs requiring robust, high-speed centrifugation.
