Herxi HR/T16MM Micro High-Speed Refrigerated Centrifuge

Overview

The Herxi HR/T16MM Micro High-Speed Refrigerated Centrifuge is an engineered benchtop solution for precise, low-volume sample separation under controlled thermal conditions. Designed around the principles of fixed-angle centrifugation and vapor-compression refrigeration, it delivers high relative centrifugal force (RCF) in a compact footprint—ideal for applications demanding rapid pelleting of nucleic acids, proteins, cellular organelles, or PCR-ready samples where volume is limited (0.2–2.0 mL) and temperature stability is critical. Its operational envelope spans −20 °C to +40 °C with ±1 °C accuracy, enabling reproducible cold-sensitive workflows such as RNA isolation, enzyme preservation, or viral particle concentration without requiring external cold rooms. The unit integrates a brushless AC frequency-controlled motor with optimized torque delivery, achieving full speed in ≤25 seconds while maintaining mechanical stability and acoustic performance below 60 dB(A)—a key requirement for shared laboratory environments.

Key Features

• Brushless AC inverter motor with Infineon driver module and custom control board for high-speed precision (±50 rpm), low vibration, and extended service life.
• Environmentally compliant refrigeration system using R404a refrigerant and fluorine-free compressor; supports pre-cooling, standby cooling, and real-time temperature adjustment during rotor spin-up/down.
• Triple-stage damping system—including asymmetric rubber mounts, dynamic counterbalance design, and proprietary composite shock absorption—minimizes sample resuspension and ensures rotor integrity at maximum RCF.
• TFT-LCD true-color touchscreen with dual-input interface (touch + physical keys); displays simultaneous setpoints and real-time parameters (speed, RCF, time, temperature, acceleration/deceleration stage); supports on-the-fly parameter modification without halting operation.
• Bio-contained fixed-angle rotor fabricated from aerospace-grade forged aluminum (EN 2024-T3 equivalent), certified for use with 0.2 mL PCR strips, 1.5 mL and 2.0 mL microtubes, and certified aerosol-tight sealing via RoHS 2015/863–compliant silicone gasketing.
• Structural safety architecture: 304 austenitic stainless steel centrifuge chamber, electrostatically sprayed steel enclosure, integrated three-layer reinforced front shield, and auto-engaging electromagnetic door lock with soft-close actuation.
• Programmable operation: 10 acceleration and 10 deceleration profiles; 20 user-defined protocol slots; automatic recall of last-used method on power-up.

Sample Compatibility & Compliance

The HR/T16MM accommodates standard microcentrifuge formats including conical-bottom 1.5 mL and 2.0 mL tubes, low-retention PCR tubes, and 8-well strip configurations—ensuring compatibility with mainstream molecular biology consumables. Its sealed rotor assembly meets biosafety requirements for containment of bioaerosols during high-speed runs, supporting safe handling of clinical, diagnostic, and BSL-2–level samples. Regulatory compliance includes CFDA registration and manufacturing authorization, ISO 9001:2015 (Quality Management Systems) and ISO 13485:2016 (Medical Device Quality Management), confirming adherence to internationally recognized production and documentation standards. While not FDA 510(k)-cleared, its design aligns with IEC 61010-1 safety directives for laboratory equipment and supports GLP-aligned recordkeeping when paired with validated data export protocols.

Software & Data Management

The embedded firmware provides audit-ready operational logging, capturing timestamped records of run parameters (start/stop time, speed, temperature, rotor ID, acceleration profile), error events (imbalance detection, overtemperature, voltage fluctuation), and maintenance alerts (refrigerant pressure thresholds, motor thermal cycles). Data export is supported via USB 2.0 interface in CSV format for integration into LIMS or ELN platforms. Multilingual UI support (English, Chinese, Russian, Portuguese) facilitates deployment across multinational research consortia and contract testing laboratories. No cloud connectivity or remote control functionality is implemented—ensuring data sovereignty and alignment with institutional IT security policies.

Applications

This centrifuge serves core workflows in molecular diagnostics, academic genomics, food safety testing, agricultural biotechnology, and clinical pathology labs. Typical use cases include: rapid pelleting of plasmid DNA post-alkaline lysis; clarification of bacterial lysates prior to chromatography; concentration of extracellular vesicles from cell culture supernatants; preparation of sequencing libraries; recovery of precipitated proteins in ammonium sulfate fractionation; and routine hematocrit-adjusted plasma separation in point-of-care validation studies. Its −20 °C capability enables direct processing of frozen-thawed specimens without intermediate equilibration steps—reducing turnaround time in high-throughput QC/QA pipelines.

FAQ

What rotor types are compatible with the HR/T16MM?
Only the factory-supplied 24-place fixed-angle aluminum rotor (part number HR-T16MM-R1) is validated and supported. Adapters for 0.2 mL PCR strips and 0.5 mL tubes are included; no swinging-bucket or continuous-flow configurations are available.
Is the unit suitable for GMP-regulated environments?
Yes—the ISO 13485:2016 certification confirms design and manufacturing controls appropriate for medical device-related sample preparation. Full traceability of calibration, preventive maintenance logs, and change control documentation must be maintained per site-specific SOPs.
Can the temperature be adjusted while the rotor is spinning?
Yes. Real-time temperature modulation is permitted across the full −20 °C to +40 °C range without interrupting rotation or requiring rotor deceleration.
Does the centrifuge support automatic rotor identification?
No. Rotor recognition is manual via operator input during protocol setup; however, the system validates maximum speed limits based on selected rotor configuration to prevent overspeed events.
What is the expected service interval for the refrigeration system?
Under normal usage (≤6 hrs/day, ambient ≤30 °C), the compressor and refrigerant loop require no scheduled maintenance for 36 months; annual verification of condenser coil cleanliness and refrigerant pressure is recommended.
