The Thermo Scientific Fiberlite F14-6×250 LE fixed-angle rotor is a carbon fiber rotor for 250 mL bottles on the Sorvall Legend XT and Multifuge X3 centrifuges. Moreover, this rotor offers the highest capacity in its class for benchtop applications. In addition, the F14-6×250 LE reaches a maximum RCF of 18,533 x g in 230V configuration. As a result, you process large volumes at superspeed level on a benchtop platform.
Furthermore, the F14-6×250 LE 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 F14-6×250 LE accommodates eleven different adapter configurations for diverse tube formats. Subsequently, you process 250 mL bottles, 100 mL Oak Ridge tubes, 50 mL conical tubes and 30 mL Oak Ridge tubes. Moreover, this rotor also offers adapters for 15 mL and 10 mL tubes, BD Vacutainer and even 3 mL blood tubes. As a result, you combine large volumes with flexible tube protocols.
Finally, the F14-6×250 LE is ideal for cell pelleting, protein precipitation and bottle applications. Therefore, this rotor is the standard choice for laboratories that need to process large volumes without a floor-model centrifuge. As a result, you switch quickly between 250 mL bottle runs and smaller tube protocols via the appropriate adapter.

Carbon fiber fixed-angle rotor for 6 x 250 mL bottles on Thermo Scientific Sorvall Legend XT and Multifuge X3 benchtop centrifuges. With a maximum RCF of 18,533 x g (230V), the F14-6×250 LE offers the highest capacity in its class. Equipped with eleven adapter configurations for tubes from 3 mL to 100 mL and Liquid containment Enhanced. Ideal for cell pelleting and protein precipitation.








The F14-6×250 LE is compatible with multiple Thermo Scientific benchtop centrifuges. Moreover, this rotor works on the Sorvall Legend XT and XTR series. In addition, the F14-6×250 LE supports the Multifuge X3 and X3R series. Furthermore, this rotor is compatible with the SL 40F series. As a result, you process large volumes on multiple Thermo Scientific benchtop platforms.
The LE-suffix in F14-6×250 LE stands for “Liquid containment Enhanced”. Moreover, this feature protects the centrifuge chamber against sample spillage in case of tube failure. In addition, the design prevents spilled liquids from contacting other parts of the rotor. As a result, you increase both sample safety and operational reliability.
The F14-6×250 LE accommodates standard 250 mL bottles and eleven different adapter configurations. Moreover, you process 100 mL Oak Ridge tubes, 50 mL conical and Oak Ridge tubes and 30 mL Oak Ridge tubes. In addition, this rotor offers adapters for 15 mL conical tubes, 15 mL Corning tubes, 10 mL Oak Ridge and BD Vacutainer tubes and even 3 mL BD Vacutainer tubes. As a result, you process tubes from 3 mL to 100 mL in the same rotor.
Carbon fiber rotors such as the F14-6×250 LE 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 F14-6×250 LE reaches 10,000 rpm in 100-120V configurations and 11,000 rpm in 230V configurations. Moreover, this means an RCF difference of 15,317 x g versus 18,533 x g. In addition, the 230V configuration is standard in European laboratories. As a result, Dutch and European users automatically benefit from the higher RCF performance.
The F14-6×250 LE is highly suitable for applications that combine large volumes with high RCF. Moreover, this rotor is the standard choice for cell pelleting and protein precipitation. In addition, this rotor accommodates 250 mL bottle applications for cell harvest, ammonium sulfate precipitation and virus pelleting. Furthermore, this rotor is suitable for sample preparation in pharmaceutical and biotechnology research.
