Sorvall SL-50T Centrifuge Rotor – 8 × 50 mL Fixed-Angle Rotor, Autoclavable at 121°C

The Sorvall SL-50T Centrifuge Rotor is a high-speed laboratory centrifuge accessory designed for separating and processing liquid samples in research, biotechnology, pharmaceutical, and biomedical laboratories. Manufactured under the Sorvall brand, this rotor is designed for compatible Sorvall Super T21 and Super T21-R centrifuge systems. It features a fixed-angle configuration and accommodates up to eight tubes with a nominal capacity of 50 mL each.

Centrifuge rotors are essential components of laboratory centrifugation systems. They hold sample containers securely and transmit rotational motion from the centrifuge drive to the samples. During centrifugation, centrifugal force promotes the separation of suspended particles, cellular components, precipitates, and other sample constituents according to their sedimentation characteristics.

The Sorvall SL-50T is designed for laboratories that require high-speed centrifugation with medium-volume sample tubes. Its eight-position configuration enables multiple samples to be processed in a single run, supporting efficient sample preparation and organized laboratory workflows. With a nominal capacity of 50 mL per tube, the rotor is suitable for applications that require larger sample volumes than standard microcentrifuge tubes can accommodate.

The rotor features a fixed-angle design with a tube angle of approximately 34 degrees. This configuration supports sedimentation and pellet formation during centrifugation. Fixed-angle rotors are commonly used in biological research, biochemical sample preparation, cellular fractionation, and other laboratory procedures where particles must be separated from a liquid suspension.

The SL-50T has a catalogue-listed maximum rotational speed of 18,500 rpm and a maximum relative centrifugal force of approximately 40,905 × g. These performance specifications make it suitable for demanding laboratory centrifugation procedures when used with the appropriate centrifuge, tubes, and approved operating parameters. Actual operating limits must be determined from the manufacturer's instructions and the condition of the individual rotor.

The rotor is manufactured from high-strength aluminum alloy, providing a rigid structure for high-speed laboratory operation. Its manufacturer documentation also identifies it as autoclavable at 121°C, which supports specified sterilization procedures when performed according to the applicable instructions. Autoclaving frequency, exposure duration, and maintenance requirements should follow the rotor manufacturer's guidelines.

The Sorvall SL-50T is intended for use with compatible tubes and approved adapters where required. Correct tube selection is important because tube dimensions, material, chemical compatibility, sample density, and permissible centrifugal force can affect safe operation. Users should confirm that all sample containers and accessories are approved for the intended speed and application.

Potential laboratory applications include cell harvesting, sedimentation of biological material, protein sample preparation, biochemical research, and processing of liquid samples. Suitability depends on the specific experimental protocol and the centrifuge configuration. The rotor should not be used for any application that exceeds its approved operating specifications.

For research institutions, university laboratories, pharmaceutical research and development departments, biotechnology facilities, and industrial laboratories, the Sorvall SL-50T provides a dedicated solution for high-speed centrifugation using compatible 50 mL sample tubes. Its multi-position arrangement can help reduce the number of runs required when processing multiple samples, improving workflow organization and laboratory productivity.

Before installation, users should inspect the rotor body, lid, locking components, and tube compartments for damage or deterioration. Samples must be balanced according to the manufacturer's instructions, and the rotor must be securely installed in the compatible centrifuge. Maximum speed limits and allowable compartment loads must be observed at all times.

The pictured rotor label confirms the SL-50T model and states that it is autoclavable at 121°C. Its serial number is visible in the photograph. However, the serial number alone does not establish the rotor's service history, remaining service life, or present operational condition. Buyers should verify these details and confirm that the supplied rotor includes the required lid and accessories.

Overall, the Sorvall SL-50T Centrifuge Rotor is a specialized laboratory accessory for high-speed separation workflows. Its 8 × 50 mL capacity, fixed-angle configuration, and compatibility with specified Sorvall centrifuge systems make it a useful option for laboratories that require reliable, model-specific centrifugation equipment.
