Thermo Scientific Sorvall Legend Micro 21R Refrigerated Microcentrifuge with Biocontainment Lid

The Thermo Scientific Sorvall Legend Micro 21R is a high-performance *refrigerated microcentrifuge* engineered for precise and efficient sample processing in molecular diagnostics, biotechnology, and clinical laboratories. This benchtop unit delivers speeds up to 14,800 RPM and generates a maximum relative centrifugal force (RCF) of 21,100 × g, making it essential for bioprocessing, gene editing workflows, and synthetic biology research requiring rapid and reliable separation of micro-volume samples.

Key technical features include:

• Refrigerated operation with temperature control from -9°C to +40°C, preserving viability of temperature-sensitive biomolecules and samples during centrifugation.
• Quiet operation at only 50 dB(A), suitable for laboratory environments requiring low noise disruption.
• Runtime adjustable from 1 to 99 minutes with an additional HOLD function for extended sample incubation.
• Safety-enhanced ClickSeal biocontainment lid, preventing aerosol contamination and supporting biosafety compliance in molecular cloning and clinical diagnostic applications.
• The centrifuge includes a 24 × 1.5/2 mL rotor compatible with common microcentrifuge tubes widely used in molecular biology and biomanufacturing pipelines.

Compact dimensions (12.9 × 11.6 × 17.5 inches) and moderate weight (~62 lbs) allow easy placement on standard laboratory benches, optimizing space without compromising high-throughput centrifugation capabilities. Certified for laboratory and clinical use under CSA, CE, and IVD standards, this unit is reliable for biomedical engineering, fluorescence-based assays, and advanced cell imaging sample preparation workflows.

This microcentrifuge is widely adopted in biotechnology research and clinical diagnostics for processes including nucleic acid extraction, protein separation, and cell fractionation, making it critical in molecular diagnostics and biopharmaceutical production environments.
