Hettich HR/T16MM Micro High-Speed Refrigerated Centrifuge

Overview

The Hettich HR/T16MM Micro High-Speed Refrigerated Centrifuge is an engineered benchtop solution designed for precision separation of low-volume biological samples under controlled thermal conditions. Utilizing fixed-angle rotor geometry and high-efficiency refrigeration, it operates on the principle of sedimentation acceleration—applying centrifugal force up to 22,500 × g to separate macromolecules, cellular organelles, nucleic acids, and particulates based on density and size differentials. Its compact footprint (680 × 350 × 300 mm) and optimized mechanical architecture make it especially suited for space-constrained environments such as molecular biology labs, clinical diagnostics units, and quality control facilities where throughput, reproducibility, and temperature stability are critical. Unlike general-purpose centrifuges, the HR/T16MM integrates active cooling during operation, enabling heat-sensitive protocols—including plasmid prep, RNA isolation, and viral pellet recovery—without thermal degradation.

Key Features

• High-torque brushless AC frequency-controlled motor with rapid acceleration/deceleration (≤25 s ramp-up), delivering stable rotational performance at speeds up to 16,500 rpm with speed accuracy of ±50 rpm.
• Environmentally compliant refrigeration system using R404a refrigerant and fluorine-free compressor; achieves and maintains setpoint temperatures from −20 °C to +40 °C with ±1 °C uniformity across the rotor chamber.
• Integrated pre-cooling and standby cooling functions ensure consistent thermal readiness prior to sample loading and during idle periods—minimizing protocol delay and thermal drift.
• TFT-LCD color display supports dual-input operation (touchscreen + physical keys), real-time parameter monitoring (set vs. actual speed, temperature, time, RCF), and on-the-fly parameter adjustment without interrupting runs.
• Biocontainment-certified fixed-angle rotor with seamless silicone O-ring seal (compliant with EU RoHS Directive 2015/863), preventing aerosol leakage during high-speed operation and meeting biosafety Level 2 (BSL-2) containment requirements.
• Triple-stage damping system combined with stainless-steel 304 rotor chamber, powder-coated steel housing, and reinforced front panel ensures mechanical integrity, vibration suppression, and operator safety during extended use.
• Programmable deceleration profiles (10 levels) and 20 user-defined method storage slots allow standardized workflows across shifts and users; last-run program auto-loads at startup.

Sample Compatibility & Compliance

The HR/T16MM accommodates standard microcentrifuge formats including 0.2 mL PCR tubes, 0.5 mL, 1.5 mL, and 2.0 mL conical tubes, as well as 8-well PCR strips. Its forged aluminum rotor provides excellent thermal conductivity and dimensional stability under repeated thermal cycling. All wetted components comply with ISO 10993 biocompatibility guidelines for non-invasive medical device applications. Regulatory documentation includes CFDA registration (Class II medical device), ISO 9001:2015 (quality management), and ISO 13485:2016 (medical device QMS)—supporting audit readiness for GLP, GMP, and CLIA-aligned laboratories. While not FDA 510(k)-cleared, its design aligns with IEC 61010-1 safety standards for laboratory equipment and meets EN 61326-1 electromagnetic compatibility requirements.

Software & Data Management

The HR/T16MM operates independently without external PC dependency; however, its embedded firmware supports full traceability through timestamped run logs stored internally (retained for ≥1,000 cycles). Each log records rotor ID, speed, temperature, duration, acceleration/deceleration profile, and fault events. The interface supports multilingual UI (English, Chinese, Russian, Portuguese) to accommodate international lab personnel. Though no proprietary software suite is provided, exported logs can be manually archived in CSV format via USB port (optional accessory) for integration into LIMS or electronic lab notebooks (ELN). Audit trail functionality satisfies basic 21 CFR Part 11 requirements for electronic records when paired with institutional SOPs governing data handling and signature protocols.

Applications

This centrifuge serves routine and specialized workflows across life science and clinical domains: nucleic acid purification (e.g., spin-column binding/elution steps), protein precipitation, cell lysate clarification, exosome isolation, antibody purification, and microbiological sample concentration. Its −20 °C capability enables cold-active enzyme preservation during centrifugation, while the 22,500 × g ceiling supports subcellular fractionation (e.g., mitochondrial isolation) and small-particle pelleting (e.g., synthetic nanoparticles <100 nm). It is routinely deployed in academic core facilities, pharmaceutical QC labs, food safety testing centers, and hospital pathology departments performing rapid turnaround assays requiring both speed and thermal control.

FAQ

What is the maximum allowable imbalance tolerance for safe operation?
The unit features dynamic imbalance detection calibrated to ≤0.5 g difference between opposing tubes; automatic shutdown occurs if imbalance exceeds this threshold.
Can the HR/T16MM accommodate 0.2 mL PCR tubes in full capacity mode?
Yes—the 24-position rotor accepts 0.2 mL tubes without adapters, maintaining rated RCF and thermal uniformity.
Is rotor autoclaving supported?
No—rotors are not autoclavable due to material specifications; cleaning is recommended with 70% ethanol and lint-free wipes per manufacturer guidelines.
Does the centrifuge support continuous run mode beyond 99 hours 59 minutes?
No—maximum timer setting is 99 h 59 min; for extended protocols, manual restart or external timing coordination is required.
How is calibration verified for speed and temperature accuracy?
Speed calibration is performed using a certified tachometer; temperature verification requires NIST-traceable probe insertion at rotor base—both procedures documented in the service manual and supported by authorized field engineers.
