The Thermo Scientific Fiberlite F15-8x50cy fixed-angle rotor is a carbon fiber rotor for 50 mL conical tubes on the Sorvall Legend and Multifuge benchtop centrifuges. Moreover, this rotor offers maximum support for disposable conical tubes through moulded cavity shapes. In addition, the F15-8x50cy reaches a maximum speed of 14,500 rpm and an RCF of 24,446 x g. As a result, you process conical tubes at superspeed level without tube damage.
Furthermore, the F15-8x50cy stands out with its carbon fiber construction and liquid containment annulus. Therefore, this rotor is considerably lighter than comparable aluminium rotors. Moreover, the annulus design offers integrated leak protection in case of tube failure. Additionally, the lightweight properties enable faster acceleration and deceleration per run.
In addition, the F15-8x50cy accommodates 8 x 50 mL disposable conical tubes via cavity geometry that fits standard conical tubes exactly. Subsequently, you process plasmid DNA preps from Qiagen Maxi and Midi protocols. Moreover, you reduce cross-contamination by centrifuging samples directly in disposable tubes. As a result, you eliminate time-consuming sample transfers and autoclaving procedures.
Finally, the F15-8x50cy complies with biocontainment certification issued by Public Health England in Porton Down. Therefore, this rotor is suitable for laboratories that work with biohazardous samples. As a result, you combine superspeed performance, conical tube efficiency and biocontainment in a single carbon fiber rotor for benchtop centrifuges.

Carbon fiber fixed-angle rotor for 8 x 50 mL conical tubes on Thermo Scientific Sorvall Legend and Multifuge benchtop centrifuges. With a maximum RCF of 24,446 x g, the F15-8x50cy offers disposable tube workflows at superspeed level. Equipped with liquid containment annulus and biocontainment certification by Public Health England. Ideal for plasmid DNA preps and protein pelleting.








The F15-8x50cy is compatible with multiple Thermo Scientific benchtop centrifuges. Moreover, this rotor works on the Sorvall Legend X1, X1R, XT and XTR series. In addition, the F15-8x50cy supports the Multifuge X1, X1R, X3 and X3R series. Furthermore, this rotor is compatible with the SL 40F series and legacy models such as Sorvall Legend T and Multifuge 3.
The cy-suffix in F15-8x50cy refers to two important properties of the rotor. Moreover, the “c” stands for conical tube support, where the cavity fits disposable conical tubes exactly. In addition, the “y” stands for liquid containment annulus, an integrated leak protection in case of tube failure. As a result, you combine optimal tube support with sample safety.
Carbon fiber rotors such as the F15-8x50cy offer multiple benefits over aluminium rotors. Moreover, these rotors weigh up to 60 percent less, making handling and installation easier. In addition, carbon fiber rotors accelerate and decelerate faster thanks to the lower mass. Furthermore, this rotor consumes less energy per run. As a result, you save time and energy per centrifugation cycle.
The F15-8x50cy accommodates standard 50 mL disposable conical tubes via moulded cavity shapes. Moreover, the cavity geometry is exactly matched to standard conical tubes from suppliers such as Falcon and Corning. In addition, this rotor offers adapters for 15 mL conical tubes. As a result, you process both 15 mL and 50 mL tubes in the same rotor.
Yes, the F15-8x50cy is biocontainment-certified by Public Health England in Porton Down. Moreover, the liquid containment annulus offers additional protection in case of tube failure. In addition, the carbon fiber material prevents corrosion from chemical spillage. As a result, you process biohazardous samples and organic solvents safely in this rotor.
The F15-8x50cy is highly suitable for applications that combine high RCF with conical tube workflows. Moreover, this rotor is the standard choice for plasmid DNA preps from Qiagen Maxi and Midi protocols. In addition, this rotor accommodates protein pelleting, cell culture applications and microbiology samples. Furthermore, this rotor is suitable for virus isolation and protein purification.
