Thermo Scientific™ Sorvall™ Legend Micro 17R Centrifuge with 24-Position Rotor – Product Introduction 

The Thermo Scientific™ Sorvall™ Legend Micro 17R Centrifuge is a high-performance refrigerated microcentrifuge designed for demanding molecular biology, clinical diagnostics, and biochemical research applications. Engineered for reliability, speed, and precision, this system is widely used in laboratories that require efficient processing of micro-volume samples such as nucleic acids, proteins, cell lysates, and PCR preparations.

Equipped with a 24-position rotor for 1.5/2.0 mL microtubes, the Legend Micro 17R delivers a perfect balance of high centrifugal force, temperature control, and operational simplicity. It is specifically optimized for workflows requiring fast turnaround times and reproducible results, making it a core instrument in modern life science laboratories.

High-Performance Refrigerated System

The Legend Micro 17R achieves a maximum relative centrifugal force of 17,000 × g, enabling rapid and efficient separation of biological materials. With a maximum speed of approximately 13,300 rpm, it provides strong and stable centrifugal performance suitable for a wide range of applications, including DNA/RNA extraction, protein precipitation, and subcellular fractionation.

As a refrigerated centrifuge, the system offers a temperature control range from -9°C to +40°C, ensuring the integrity of temperature-sensitive samples. The compressor-based cooling system can reach 4°C in approximately 8–9 minutes, helping preserve biomolecules and prevent enzymatic degradation during high-speed runs. This makes it especially suitable for genomics, proteomics, and clinical sample processing.

24-Position Rotor System

The included 24 × 1.5/2.0 mL fixed-angle rotor is designed for high-throughput microcentrifugation. It is compatible with standard Eppendorf-style tubes and features a durable, corrosion-resistant construction for long-term laboratory use.

Many configurations include a ClickSeal biocontainment lid, which provides aerosol-tight sealing during centrifugation. This significantly enhances laboratory biosafety by minimizing exposure to potentially hazardous biological samples. The rotor supports balanced loading and smooth operation even at maximum speed, ensuring stability and reducing vibration.

Intelligent Operation and User Interface

The Sorvall Legend Micro 17R is designed with an intuitive digital control panel that allows users to easily adjust speed, time, and temperature settings. The display enables quick switching between RPM and RCF values, ensuring accuracy and reproducibility across different experimental protocols.

It supports run times from 1 to 99 minutes, as well as continuous operation (HOLD mode). A dedicated Quick Run/Pulse function allows rapid short spins, improving workflow efficiency in routine laboratory tasks.

The system also includes advanced microprocessor control for acceleration and deceleration, ensuring smooth ramp-up and braking profiles that protect delicate samples from disturbance.

Safety and Reliability

Safety is a key design feature of the Legend Micro 17R. The instrument includes multiple protective systems such as:

• Lid interlock system preventing operation when the lid is open

• Imbalance detection for automatic shutdown

• Rotor overspeed protection

• Aerosol-tight sealing system (with ClickSeal lid)

These safety features ensure compliance with international laboratory standards, including CE and IEC 61010 safety certifications, making it suitable for regulated environments such as clinical and pharmaceutical laboratories.

Quiet and Efficient Operation

Despite its high-speed capability, the centrifuge operates at a low noise level of approximately ≤50 dB(A). This allows it to be used comfortably in shared laboratory spaces, clean benches, and biosafety cabinets without causing disruption. Its vibration-minimized motor design ensures smooth and stable performance even under full load conditions.

Applications

The Thermo Scientific Legend Micro 17R is widely used in:

• DNA and RNA extraction workflows

• PCR and qPCR sample preparation

• Protein purification and precipitation

• Cell and subcellular fractionation

• Clinical diagnostic sample processing

• Enzyme and molecular biology research

• Routine microcentrifugation tasks

Its versatility makes it a standard instrument in molecular biology, biotechnology, and clinical research laboratories worldwide.
