The Thermo Scientific Fiberlite F13S-14x50cy fixed-angle rotor is a carbon fiber rotor for 14 conical tubes of 50 mL. Moreover, this rotor offers the highest 50 mL conical capacity for the Sorvall Legend X1 and Multifuge X1 series. In addition, the F13S-14x50cy reaches a maximum RCF of 17,105 x g in 230V configuration on the Legend XT. As a result, you process large series of conical tubes efficiently on a benchtop centrifuge.
Furthermore, the F13S-14x50cy 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 F13S-14x50cy accommodates 14 disposable conical tubes of 50 mL 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 F13S-14x50cy offers six adapters for smaller tube formats besides the standard 50 mL conical. Therefore, this rotor is suitable for laboratories that combine 50 mL workflows with smaller-volume protocols. As a result, you switch quickly between 50 mL conical runs and 10 mL or 15 mL tube applications via the appropriate adapter.

Carbon fiber fixed-angle rotor for 14 x 50 mL conical tubes on Thermo Scientific Sorvall Legend and Multifuge benchtop centrifuges. With a maximum RCF of 17,105 x g (230V), the F13S-14x50cy offers the highest 50 mL conical throughput in its class. Equipped with liquid containment annulus and biocontainment certification by Public Health England. Ideal for plasmid DNA preps and high-throughput conical workflows.








The F13S-14x50cy is compatible with multiple Thermo Scientific benchtop centrifuges. Moreover, this rotor works on the Sorvall Legend X1 and X1R series at 8,500 rpm. In addition, the F13S-14x50cy supports the Sorvall Legend XT, XTR and Multifuge X3, X3R series at 9,250 rpm (230V: 10,000 rpm). Furthermore, this rotor is compatible with the SL 40F series and legacy models via SKU 75006526.
The cy-suffix in F13S-14x50cy 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.
The F13S-14x50cy offers a capacity of 14 x 50 mL and reaches 17,105 x g, whereas the F15-8x50cy offers a capacity of 8 x 50 mL and reaches 24,446 x g. Moreover, the F13S-14x50cy provides more throughput per run thanks to the extra positions. Conversely, the F15-8x50cy reaches higher RCF values. Therefore, choose the F13S-14x50cy for maximum throughput and the F15-8x50cy for higher RCF.
The F13S-14x50cy accommodates standard 50 mL disposable conical tubes via moulded cavity shapes. Moreover, this rotor offers six adapter configurations for smaller tube formats. In addition, you process 50 mL Oak Ridge tubes, 30 mL Oak Ridge tubes, 16 mL Oak Ridge tubes and 15 mL conical tubes. Furthermore, this rotor accommodates 15 mL Millipore filtration devices and 10 mL BD Vacutainer tubes.
Yes, the F13S-14x50cy 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 F13S-14x50cy is highly suitable for high-throughput 50 mL conical 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 sample preparation in pharmaceutical and biotechnology research.
