Thermo Scientific FiberLite F21-48x1.5/2.0y Fixed-Angle Rotor, 21,000 RPM, 48x1.5 mL Capacity

The Thermo Scientific FiberLite F21-48x1.5/2.0y is a high-performance fixed-angle rotor engineered for Thermo Scientific Jouan KR22i centrifuges, optimized for demanding molecular biology and bioprocessing applications. Constructed from a durable carbon fiber composite, this rotor supports a capacity of 48 tubes (1.5 mL), accommodating microcentrifuge tubes critical for workflows such as gene editing and molecular cloning.

• Maximum speed: 21,000 RPM enables high centrifugal force generation up to 43,500 × g, essential for efficient pelleting and phase separation in cell imaging and synthetic biology protocols.
• Fixed angle: 25°, suitable for rapid sedimentation in protocols requiring consistent positioning of samples.
• Biocontainment feature: Ensures safety during high-speed runs with potentially biohazardous samples, essential for molecular diagnostics and clinical research laboratories.
• Physical specs: Radius ranges from 64 mm min to 97 mm max, K factor of 221 for performance benchmarking, supporting tubes up to 40 mm length and 11 mm diameter.
• Net weight: 3.81 kg (8.4 lb), fabricated for durability and reliability during repetitive biomanufacturing centrifugation cycles.

This rotor is widely used in biotechnology and clinical diagnostics environments, supporting applications from synthetic biology research to critical biopharmaceutical production pipelines. Its robust construction and compatibility with Jouan KR22i centrifuges make it an indispensable tool for laboratories requiring precise and safe centrifugation of small-volume samples.
