Hettich HR/T16M Benchtop High-Speed Refrigerated Centrifuge

Overview

The Hettich HR/T16M is a benchtop high-speed refrigerated centrifuge engineered for precision separation tasks in regulated and research-intensive laboratory environments. It operates on the principle of sedimentation under controlled rotational force—generating up to 19,600 × g at 16,000 rpm—to separate biological macromolecules, subcellular organelles, precipitated proteins, nucleic acids, and particulate matter from liquid suspensions. Its integrated refrigeration system maintains sample integrity during prolonged or heat-sensitive runs, making it suitable for applications where thermal denaturation must be minimized—such as RNA isolation, mitochondrial enrichment, or plasma fractionation. Designed for compliance-driven workflows, the HR/T16M meets essential quality management requirements for in vitro diagnostic (IVD) support, clinical specimen processing, and GMP-adjacent research operations.

Key Features

• Brushless DC inverter motor with microprocessor-based control ensures stable rotor acceleration/deceleration, low mechanical drift, and long-term operational reproducibility.
• Imported hermetic refrigeration unit using environmentally compliant R404a refrigerant enables precise temperature maintenance between −20 °C and +40 °C, with pre-cooling and standby cooling functions to reduce thermal equilibration time.
• TFT-LCD true-color display supports dual-input operation (touchscreen + physical keys), real-time parameter monitoring (set vs. actual speed, RCF, temperature, time), and on-the-fly parameter adjustment without interrupting the run.
• Biocontainment-compliant fixed-angle rotor with integrated silicone O-ring seal (conforming to EU RoHS Directive 2015/863) prevents aerosol leakage during high-speed operation—critical for biosafety level 2 (BSL-2) handling of clinical or pathogenic samples.
• Triple-layer safety architecture: austenitic 304 stainless steel centrifuge chamber, powder-coated steel housing, and reinforced front panel with impact-resistant polymer overlay provide structural integrity and operator protection.
• 10-step programmable acceleration and deceleration profiles minimize sample resuspension; 20 user-defined protocols can be stored and recalled instantly, including last-run auto-resume functionality.
• Electromechanical door lock system engages automatically upon lid closure, eliminating manual latching errors and ensuring interlock compliance prior to rotor spin-up.

Sample Compatibility & Compliance

The HR/T16M accommodates standard conical tubes (1.5–2.0 mL), PCR strips, deep-well plates (96-well and 384-well), and custom adapters for polypropylene or polyamide fiber carriers. Its maximum capacity of 4 × 100 mL supports scalable preparative workflows without requiring floor-standing instrumentation. All rotors are CNC-machined from aerospace-grade aluminum alloy and undergo dynamic balancing per ISO 1940–1 (G2.5 grade). The instrument holds CFDA registration and manufacturing license for Class II medical devices in China, and complies with ISO 9001:2015 (Quality Management Systems) and ISO 13485:2016 (Medical Devices)—supporting traceability, calibration documentation, and audit readiness in GLP and GMP-aligned laboratories.

Software & Data Management

While the HR/T16M does not include networked software or remote control capability, its embedded firmware logs all critical run parameters—including start/stop timestamps, final rotor speed, achieved RCF, chamber temperature profile, and fault codes—for local review via display history or printed output (when connected to optional thermal printer interface). The system supports multi-language UI (English, Chinese, Russian, Portuguese) and retains settings across power cycles. For regulatory environments requiring electronic records, users may integrate external logging systems via RS-232 or USB serial emulation (firmware version 2.3+), enabling alignment with FDA 21 CFR Part 11 requirements when paired with validated third-party data acquisition platforms.

Applications

• Nucleic acid purification (plasmid DNA, genomic DNA, total RNA) from bacterial lysates or mammalian cell pellets.
• Subcellular fractionation: isolation of nuclei, mitochondria, lysosomes, and microsomes using differential centrifugation protocols.
• Clinical diagnostics: serum/plasma separation from whole blood, PBMC isolation, and viral pellet concentration for ELISA or PCR downstream analysis.
• Food safety testing: pathogen enrichment (e.g., Salmonella, Listeria) from homogenized food matrices prior to culture or molecular detection.
• Environmental microbiology: sedimentation of waterborne particulates and biofilm fragments for metagenomic sequencing library prep.
• Biopharmaceutical QC: clarification of recombinant protein supernatants and removal of cellular debris prior to chromatographic purification.

FAQ

What is the minimum achievable temperature during operation?
The unit maintains setpoint temperatures down to −20 °C under full-load conditions at maximum speed, verified per IEC 61010-2-020 thermal stability testing.
Can the HR/T16M accommodate swing-bucket rotors?
No—this model is configured exclusively for fixed-angle rotor geometry to optimize high-speed performance and RCF uniformity.
Is rotor imbalance detection automated?
Yes—the control system continuously monitors vibration amplitude and current draw; automatic shutdown occurs if imbalance exceeds ISO 1940–1 Class G2.5 thresholds.
Does the device support validation documentation packages?
Hettich provides IQ/OQ documentation templates aligned with ISO/IEC 17025 and ASTM E2500-13, including calibration certificates for speed and temperature sensors.
What maintenance intervals are recommended?
Compressor oil inspection every 24 months; rotor lifetime tracking via embedded counter; annual verification of door interlock, refrigerant pressure, and brake response time by certified service technician.
