Hercy TL8R Benchtop Low-Speed Refrigerated Centrifuge

Overview

The Hercy TL8R is a floor-standing, low-speed refrigerated centrifuge engineered for high-throughput, temperature-sensitive separation tasks in regulated laboratory environments. Operating on the principle of sedimentation under controlled gravitational force (RCF), it delivers stable, reproducible separations across diverse sample matrices—including whole blood, cell suspensions, tissue homogenates, and polymer solutions—without inducing thermal degradation or mechanical shear damage. Its design prioritizes operational continuity and environmental integrity: the compressor-based cooling system maintains precise temperature control (−20 °C to +40 °C) throughout the run, including during acceleration and deceleration phases. Unlike air-cooled units, the TL8R employs a hermetically sealed R404a refrigeration circuit compliant with EU F-Gas Regulation (EU No 517/2014) and RoHS 2015/863, ensuring both regulatory alignment and long-term thermal stability.

Key Features

• Robust AC brushless motor with Infineon driver ICs and proprietary control firmware—enabling smooth start-up, minimal acoustic emission (<58 dB(A) at 1 m), and extended service life under continuous operation.
• Triple-stage composite damping architecture: primary rubber isolation mounts, secondary tuned mass dampers, and tertiary rotor suspension geometry—reducing vibration transmission by >92% compared to conventional single-damp systems.
• Bi-directional programmable ramp control (10 acceleration/deceleration profiles) prevents sample resuspension during braking and accommodates fragile pelleted structures such as lymphocytes or extracellular vesicles.
• TFT-LCD graphical interface supports dual-input operation (capacitive touch + tactile keys), real-time display of RCF, rpm, temperature, time, and rotor-specific parameters—and allows live parameter adjustment without interrupting the run.
• Integrated safety suite includes real-time imbalance detection (via dynamic load monitoring), overtemperature cutoff (±0.5 °C accuracy), overspeed protection (hardware-based independent watchdog), and voltage fluctuation compensation (180–242 V AC, 50/60 Hz).
• CE-marked bioclosure system: swing-bucket rotors feature molded silicone gaskets meeting ISO 10993-5 cytotoxicity standards; lid sealing achieves Class II biological containment per EN 14122-3 for aerosol mitigation during high-volume processing.

Sample Compatibility & Compliance

The TL8R accommodates standard clinical and research formats—including 50 mL conical tubes, 100 mL bottles, and custom 750 mL centrifuge bottles—within its 4-position horizontal rotor configuration. All rotors are dynamically balanced to ISO 21501-4 specifications and validated for repeated sterilization via autoclaving (121 °C, 20 min). The unit complies with IEC 61010-1:2010 for electrical safety in laboratory instrumentation and meets EMC requirements per EN 61326-1:2013. Its software architecture supports audit trail generation (user ID, timestamp, parameter changes, error logs) aligned with GLP and GMP documentation practices. CFDA registration (Registration No. Hunan械备2022XXXXX) and ISO 13485:2016 certification confirm its suitability for in vitro diagnostic (IVD) sample preparation workflows under Chinese NMPA and international harmonized frameworks.

Software & Data Management

While the TL8R operates as a standalone instrument, its embedded controller stores up to 20 user-defined protocols with full parameter recall—including rotor ID, speed profile, temperature setpoint, and hold time. Each protocol retains version-stamped execution history accessible via USB export (CSV format). Optional RS-485 serial interface enables integration into centralized lab management systems (LIMS) for remote status polling and event logging. Firmware updates are performed via secure USB key with SHA-256 signature verification, satisfying traceability requirements under FDA 21 CFR Part 11 Annex 11 when deployed in regulated QC/QA settings.

Applications

The TL8R serves core separation needs across multiple disciplines: clinical hematology (RBC/WBC fractionation, platelet-rich plasma isolation), pharmaceutical process development (clarification of microbial lysates, polymer precipitation), food safety testing (pathogen concentration from liquid matrices), agricultural biochemistry (chloroplast isolation, starch granule purification), and environmental microbiology (waterborne pathogen recovery). Its wide temperature range and high-volume capacity make it especially suited for batch processing in blood banks, vaccine manufacturing support labs, and contract research organizations handling large-scale bioprocess intermediates.

FAQ

Does the TL8R support rotor auto-recognition?
No—rotor identification is manual via selection in the setup menu; however, each stored protocol embeds rotor-specific safety limits to prevent overspeed operation.
Can the refrigeration system operate during standby mode?
Yes—the “Standby Cooling” function maintains chamber temperature within ±1 °C of setpoint without rotor rotation, minimizing thermal shock upon sample loading.
Is the unit compatible with third-party rotors?
Only Hercy-certified rotors are supported; use of non-approved hardware voids safety certification and invalidates ISO 13485 compliance.
What maintenance intervals are recommended?
Compressor oil inspection every 24 months; refrigerant pressure check annually; rotor lifetime tracking via built-in usage counter (max. 10,000 cycles per rotor).
How is data integrity ensured during power interruption?
Non-volatile memory retains all active protocols and last-run parameters; upon restart, the system defaults to safe idle state with audible alert and visual prompt for operator confirmation.
