Haier Xiangyun LX-165T2R Benchtop High-Speed Micro-Ultracentrifuge with Active Noise Suppression

Overview

The Haier Xiangyun LX-165T2R is a benchtop refrigerated high-speed centrifuge engineered for precision separation of temperature-sensitive biomolecules—including nucleic acids, proteins, organelles, and bacterial pellets—in research, clinical diagnostics, and quality control laboratories. It operates on the principle of sedimentation under controlled gravitational force (RCF), where rotational acceleration induces differential migration of particles based on size, density, and shape within viscous media. With a maximum speed of 16,500 rpm and RCF up to 25,872 × g, the LX-165T2R delivers robust performance for micro-volume applications requiring both thermal stability and mechanical reproducibility. Its compact footprint (height only 240 mm) and ultra-low center-of-gravity design optimize ergonomic access while minimizing vibration transmission—critical in shared lab environments where spatial constraints and acoustic compliance are prioritized.

Key Features

• Active noise suppression architecture: Acoustic damping housing, balanced rotor dynamics, and inverter-driven motor/fan reduce operational noise to ≤52 dB(A) at 1 m—meeting ISO 7779 and EU Directive 2006/42/EC requirements for laboratory equipment.
• Intelligent dual-inverter refrigeration: Independent frequency-controlled compressor and axial fan enable rapid chamber pre-cooling (<5 min from ambient to −20 °C) and precise temperature maintenance (±2 °C) across the full −20 °C to +40 °C range.
• 7-inch multi-touch LCD interface: Glove-compatible operation with intuitive menu navigation; supports user-defined protocols, real-time curve visualization, and zoomable run history graphs.
• Gyroscopic dynamic imbalance detection: Real-time monitoring of rotational axis deviation ensures automatic deceleration if imbalance exceeds safety thresholds—compliant with IEC 61010-2-020 for centrifuge-specific safety.
• RFID-enabled rotor identification: Each fixed-angle rotor carries a unique ID tag; system auto-detects rotor type, validates maximum speed limits, and logs cumulative usage hours for predictive maintenance and GLP traceability.
• Brushless DC inverter motor: Maintenance-free operation with extended service life (>20,000 h MTBF), consistent torque delivery, and programmable acceleration/deceleration profiles (20 s / 32 s standard).
• Comprehensive data governance: USB export of audit-ready run logs (timestamp, RCF, temp, duration, rotor ID); optional integration with LIMS via CSV or XML schema.

Sample Compatibility & Compliance

The LX-165T2R accommodates standard microcentrifuge tubes (1.5 mL and 2.0 mL) in its 24-position fixed-angle rotor—optimized for pelleting subcellular fractions, precipitating plasmid DNA, concentrating viral particles, or clarifying protein lysates. All internal surfaces are constructed from medical-grade stainless steel (AISI 304) and corrosion-resistant polymer composites. The unit complies with key international standards including IEC 61010-1 (safety), IEC 61326-1 (EMC), ISO 13485 (medical device QMS), and meets essential requirements of the EU Medical Device Regulation (MDR 2017/745) for Class I non-sterile laboratory instruments. Temperature calibration is traceable to NIST-certified references; validation documentation supports IQ/OQ protocols per FDA 21 CFR Part 11 and ISO/IEC 17025.

Software & Data Management

No external software installation is required—the embedded firmware provides full local control and data logging. Each user account supports password-protected profile storage (unlimited protocols), individual audit trails, and timestamped run records with graphical RCF/time and temperature/time overlays. Data exports include metadata such as rotor serial number, operator ID, environmental conditions, and system health flags. For regulated environments, the system supports electronic signatures, event-driven alerts (e.g., door open mid-run), and configurable retention policies aligned with ALCOA+ principles. Firmware updates are delivered via secure USB transfer with SHA-256 checksum verification.

Applications

• Purification of plasmid DNA, genomic DNA, and RNA from bacterial cultures or mammalian cells
• Preparation of cytoplasmic/nuclear extracts and mitochondrial isolates
• Concentration of low-titer viral vectors (AAV, lentivirus) and exosomes
• Routine QC of monoclonal antibody formulations prior to HPLC analysis
• Removal of cellular debris from clarified lysates in recombinant protein workflows
• High-throughput sample preparation for next-generation sequencing library construction

FAQ

What is the minimum operating temperature, and how quickly does the chamber reach it?
The chamber achieves −20 °C from ambient (25 °C) in under 5 minutes using the dual-inverter refrigeration system.
Does the centrifuge support regulatory-compliant data archiving for GxP environments?
Yes—run logs include immutable timestamps, operator IDs, rotor usage metrics, and environmental parameters; export formats meet 21 CFR Part 11 requirements for electronic records.
Can multiple users store and protect their own centrifugation protocols?
Yes—the multi-level user management system assigns independent passwords and isolated protocol libraries per account.
Is rotor lifetime tracking automated and auditable?
Yes—RFID-based rotor ID recognition logs cumulative run time and max-speed cycles; alerts trigger at 90% of manufacturer-specified service life.
What safety certifications does the LX-165T2R hold?
It conforms to IEC 61010-1, IEC 61010-2-020, IEC 61326-1, and carries CE marking under the EU MDR framework for laboratory instrumentation.
