HR/T20M High-Speed Refrigerated Centrifuge

Overview

The HR/T20M High-Speed Refrigerated Centrifuge is an engineered solution for high-throughput, temperature-sensitive separation tasks in modern life science and clinical laboratories. Designed around the principles of sedimentation velocity centrifugation under controlled thermal conditions, it enables reproducible isolation of biomacromolecules—including nucleic acids, proteins, subcellular organelles, and viral particles—by applying precise centrifugal forces up to 27,700 × g. Its refrigerated architecture maintains sample integrity during prolonged runs, critical for preserving enzymatic activity, preventing denaturation, and minimizing thermal degradation in sensitive biological matrices. The system operates within a validated temperature range of −20 °C to +40 °C, with ±1 °C stability, supporting protocols aligned with ISO 20387 (biobanking), CLSI EP05-A3 (precision evaluation), and USP <1058> (analytical instrument qualification).

Key Features

• Brushless frequency-controlled motor delivering high torque, low vibration, and extended service life—engineered for >20,000 rpm operation with ±50 rpm speed accuracy.
• Triple-layer reinforced steel rotor chamber and integrated mechanical/electronic imbalance detection ensure structural integrity and operator safety per IEC 61010-2-020 (safety requirements for laboratory centrifuges).
• Imported R404a-based non-CFC refrigeration system achieves rapid cooling (<15 min from ambient to −20 °C) and stable thermal control, including standby cooling while the rotor remains at rest.
• Ergonomic front-loading design with electro-mechanical door lock, LCD touchscreen interface, and real-time dual-parameter display (setpoint vs. actual RPM/RCF/temperature/time).
• Programmable operation: 20+ preset protocols, user-defined method storage, 9-step acceleration/deceleration ramping, and momentary spin (“pulse”) function for quick pellet settling.
• Full stainless-steel centrifuge chamber and corrosion-resistant internal surfaces comply with ISO 13485 cleanability requirements for diagnostic and GMP-adjacent environments.

Sample Compatibility & Compliance

The HR/T20M accommodates diverse sample formats via interchangeable rotors: fixed-angle rotors for high-RCF pelleting (e.g., 12 × 1.5/2.0 mL tubes at 20,000 rpm, 6 × 50 mL at 12,000 rpm), horizontal rotors for density-gradient separations (e.g., 12 × 10 mL at 4,000 rpm), and microplate carriers for high-throughput serum/plasma processing. All rotors are CE-marked and certified for maximum rated speeds per ISO 15841. The system supports GLP/GMP workflows through audit-trail-capable parameter logging (when paired with optional data export modules), and its thermal performance is verified per ASTM F2623-22 (performance testing of refrigerated centrifuges). It meets essential requirements of the EU Machinery Directive 2006/42/EC and electromagnetic compatibility per EN 61326-1.

Software & Data Management

While the HR/T20M operates autonomously via its embedded controller, optional USB data export enables traceable recordkeeping of run logs—including date/time stamp, rotor ID, speed, temperature, duration, and error codes—for compliance with FDA 21 CFR Part 11 (when used with validated third-party LIMS integration). Method templates can be saved, recalled, and duplicated across instruments, reducing setup variability in multi-user labs. Firmware updates are performed via secure USB interface, ensuring alignment with evolving regulatory expectations for instrument calibration and verification documentation.

Applications

• Isolation of plasmid DNA, genomic DNA, and RNA from bacterial, mammalian, and plant lysates.
• Purification of exosomes, microvesicles, and lipoprotein fractions (e.g., HDL/LDL) using differential ultracentrifugation protocols.
• Preparation of mitochondrial, nuclear, and lysosomal fractions in cell fractionation studies.
• Clarification of crude enzyme extracts, antibody supernatants, and vaccine intermediates prior to chromatography or filtration.
• Routine processing of whole blood, serum, plasma, and CSF in clinical diagnostics and biobanking operations.
• Stabilization of thermolabile reagents and standards during QC/QA sample preparation in pharmaceutical manufacturing.

FAQ

What is the maximum relative centrifugal force (RCF) achievable with the HR/T20M?
The HR/T20M delivers up to 27,700 × g when using the standard 12 × 1.5/2.0 mL fixed-angle rotor at 20,000 rpm.
Does the centrifuge support rotor auto-recognition?
No—rotor identification is manual via selection on the touchscreen interface; users must confirm rotor type and max speed before initiating runs.
Can the HR/T20M maintain −20 °C during a 4-hour continuous run?
Yes—the refrigeration system is rated for sustained operation at −20 °C under full load (4 × 100 mL), verified per manufacturer thermal load testing protocols.
Is the unit compliant with international electrical safety standards?
Yes—it conforms to IEC 61010-1 (general safety), IEC 61010-2-020 (centrifuge-specific), and EN 61326-1 (EMC), with full CE certification documentation available upon request.
Are rotor certificates of conformance and balancing reports provided?
Each rotor is supplied with a factory-issued certificate indicating serial number, material grade (e.g., aluminum alloy 7075-T6), dynamic balance grade (G2.5 per ISO 1940-1), and maximum allowable speed validation.
