Thermo Scientific Sorvall ST 40R Refrigerated Benchtop Centrifuge 4x1000mL

The Thermo Scientific Sorvall ST 40R Refrigerated Benchtop Centrifuge (Model 75004525) is engineered for advanced laboratory sample processing with applications in biotechnology, molecular diagnostics, and clinical research. This unit supports a high-capacity volume of 4 x 1000mL with sealed biocontainment rotors (rotor not included), delivering speeds up to 15,200 RPM and a maximum relative centrifugal force (RCF) of 25,314 x g, essential for efficient sample pelleting and phase separation.

Key technical features include:

• Refrigeration system operational within a temperature range of -10 to +40°C, critical for preserving biomolecules and temperature-sensitive samples during centrifugation in bioprocessing and synthetic biology workflows.
• Advanced rotor management with Auto-Lock III Rotor System and ClickSeal Bucket Sealing ensuring secure rotor containment and safety compliance.
• Equipped with SMARTSpin Technology for optimized run profiles, enabling precise acceleration/deceleration with 9 acceleration and 10 braking profiles to minimize shear stress on delicate biological samples.
• Microprocessor-controlled interface with a digital display supports up to 6 programmable run methods, direct access controls, and extended run times up to 9 hours and 99 minutes plus HOLD, suitable for diverse experimental protocols.
• Drive system utilizes a direct, brushless induction motor for reliable high-speed operation with noise levels below 61 dBA, facilitating use in sensitive laboratory environments.

Though sold AS-IS due to operational faults including lid error codes (E24, E97), motor block error (E29), and a bent spindle, the refrigeration function and major components remain intact. This centrifuge represents a valuable resource for skilled refurbishment or as a source of spare parts for high-capacity refrigerated sample separation needs in molecular biology, gene editing, and biomanufacturing applications.

Dimensions and weight specifications (138.8 kg) conform to standard benchtop laboratory equipment requirements, with electrical operation at 120V, 60Hz. This centrifuge is classified under Harmonized Code 842119, confirming its primary use in laboratory centrifugation for separation of biological materials.

This model is widely adopted in research fields involving live-cell centrifugation, vaccine development, and synthetic biology workflows, making it a critical instrument for laboratories engaged in biotechnology process optimization and molecular diagnostics development.
