Overview of the Thermo Scientific Sorvall ST 8 Benchtop Centrifuge
The Thermo Scientific Sorvall ST 8 is a non-refrigerated benchtop centrifuge optimized for blood processing, clinical sample preparation, microbiology applications, biotechnology workflows, cell culture preparation, and general laboratory centrifugation procedures. Unlike specialized centrifuges designed for a single sample format, the ST 8 is intended to serve as a flexible platform capable of supporting multiple laboratory workflows.
This particular system includes the Thermo Scientific TX-150 swinging bucket rotor. Swinging bucket rotors are often preferred for blood processing, plasma preparation, serum separation, and cell culture applications because samples achieve a horizontal orientation during centrifugation. This orientation often improves separation quality and sample recovery compared to fixed-angle rotor designs.
The combination of the Sorvall ST 8 platform and TX-150 rotor makes this system particularly valuable in biotechnology companies, clinical laboratories, academic research institutions, hospital laboratories, pharmaceutical facilities, and educational laboratories.
