Sorvall Heraeus 6444 High-Speed Rotor for Thermo Scientific Refrigerated Centrifuges

The Sorvall Heraeus 6444 rotor is a high-speed centrifuge rotor compatible with Thermo Scientific Sorvall Legend RT/T Plus, Sorvall RC4 Series, Heraeus Cryofuge 5500i, and Heraeus Multifuge 4 refrigerated centrifuges. Designed for advanced biotechnology applications including molecular diagnostics and bioprocessing workflows, this rotor supports efficient microplate centrifugation.

Key features include:

• Maximum speed: 5,250 rpm with a resultant centrifugal force of up to 5,083 x g, suitable for cell pelleting and sample clarification in synthetic biology and molecular cloning workflows.
• Capacity: Accommodates 2 large-bottom microplates or 10 standard microplates, enabling high-throughput sample processing fundamental in biomanufacturing and biomedical engineering research.
• Rotor diameter: 33 cm with a maximum radius of 16.5 cm, optimized for uniform sample acceleration and deceleration.
• Load capacity: Rated for 2 x 500 ml plates with a maximum permitted centrifugal load of 2 x 523 g.
• Acceleration/Deceleration: Controlled acceleration and deceleration times of 110 and 55 seconds respectively, minimizing shear stress on sensitive biological samples during centrifugation.
• Temperature management: Supports sample cooling with aerosol-tight adjustment, maintaining samples near 13°C during 1-hour runs at room temperature of 23°C, essential for preserving biomolecular integrity in cell imaging and fluorescence analysis protocols.

The Heraeus 6444 rotor is critical for precision centrifugation tasks in clinical diagnostics and biopharmaceutical production pipelines, widely adopted in research requiring reproducible sample concentration and fractionation. Its compatibility with multiple refrigerated centrifuge models ensures versatility across diverse laboratory environments.
