Overview
The Hercy TDZ5-WS is a precision-engineered benchtop low-speed centrifuge designed for routine separation tasks in life science, clinical diagnostics, food safety, agricultural research, and pharmaceutical quality control laboratories. Operating on the principle of sedimentation force generation via rotational acceleration, the TDZ5-WS delivers reproducible, high-yield pelleting and phase separation across diverse sample types—including whole blood, cell suspensions, tissue homogenates, and particulate-laden solutions—without inducing thermal or mechanical stress associated with high-speed operation. Its optimized rotor dynamics and thermally stable drive architecture ensure consistent performance over extended duty cycles, supporting both batch processing and time-sensitive workflows in regulated environments.
Key Features
- High-torque brushless DC motor coupled with proprietary microcontroller (Infineon driver module + Yingruien MCU) enables precise speed regulation (±50 rpm accuracy), low operational noise (≤60 dB[A]), and extended service life without carbon brush wear.
- Dual-mode human interface: 5.7-inch TFT-LCD true-color display with tactile keypad and capacitive touch support; real-time dual-parameter view (set vs. actual rpm/RCF/time); on-the-fly parameter adjustment during active runs.
- Comprehensive safety architecture: triple-stage damping system, automatic imbalance detection, overspeed/overtemperature/under-voltage/over-voltage alarms, and electro-mechanical door interlock with silent magnetic latch mechanism.
- Biocontainment-certified angular rotors sealed with RoHS 2015/863-compliant silicone elastomer gaskets to prevent aerosol escape during centrifugation of infectious or volatile samples.
- Robust chamber construction: AISI 304 stainless steel centrifuge chamber, powder-coated steel housing, stamped steel front panel, and triple-layer reinforced safety hood meet IEC 61010-2-020 mechanical integrity requirements.
- Universal voltage compatibility (100–230 V AC, 50/60 Hz) ensures stable operation across global laboratory power infrastructures; optional wide-range input module available upon request.
Sample Compatibility & Compliance
The TDZ5-WS accommodates standard laboratory consumables including conical tubes (10–100 mL), microtiter plates (96-well, deep-well, PCR), and cell culture vessels via interchangeable rotors—angular (12 × 15 mL, max 5000 rpm / 3120 ×g), horizontal (4 × 100 mL, max 5000 rpm / 4514 ×g), and plate-specific carriers (2 × 96-well, max 4000 rpm / 2360 ×g). All rotors are certified for autoclaving (121°C, 20 min) and manufactured from aerospace-grade forged aluminum (angular) or reinforced polyamide fiber (adapters). The system complies with ISO 9001:2015 (quality management) and ISO 13485:2016 (medical device manufacturing), and holds CFDA registration as a Class II in vitro diagnostic support device. While not FDA 510(k)-cleared, its design aligns with CLSI EP05-A3 and ISO 20943 guidance for centrifuge validation in GLP/GMP-aligned settings.
Software & Data Management
The TDZ5-WS operates via embedded firmware with no external PC dependency. All 20 programmable methods—including ramp profiles, hold times, and RCF-targeted setpoints—are stored non-volatily and recalled at power-on as last-used protocol. Audit trail functionality logs timestamped run records (start/stop time, rotor ID, speed, duration, error codes) to internal flash memory, supporting basic traceability per ISO/IEC 17025 clause 7.7. Optional RS-232 serial output enables integration with LIMS or lab automation systems for centralized job scheduling and raw data export. Language localization includes English, Chinese, Russian, and Portuguese UI variants, configurable via setup menu.
Applications
This centrifuge is routinely deployed in: blood bank operations (RBC/WBC separation, platelet harvesting), clinical chemistry (serum/plasma isolation from clotted specimens), microbiology (bacterial pellet concentration prior to Gram staining or MALDI-TOF preparation), food testing labs (fat extraction from dairy emulsions, pathogen enrichment in broth), and plant biochemistry (chloroplast or starch granule isolation from leaf homogenates). Its gentle yet effective sedimentation profile makes it especially suitable for fragile organelles, antibody-antigen complexes, and polymer-based nanocarriers where excessive g-force would compromise structural integrity.
FAQ
What is the maximum relative centrifugal force (RCF) achievable with the 4 × 100 mL horizontal rotor?
The 4 × 100 mL horizontal rotor reaches 4514 ×g at 5000 rpm.
Does the TDZ5-WS support continuous operation mode?
Yes—timer can be set to “Continuous” for uninterrupted spinning until manually stopped.
Are rotor identification chips or auto-rotor recognition features included?
No; rotor selection and safety limits must be manually confirmed by the operator prior to run initiation.
Can this centrifuge be validated for use in GMP-regulated environments?
While not pre-validated, its documented performance specifications, audit-trail-capable firmware, and ISO 13485-certified manufacturing process provide foundational evidence for IQ/OQ/PQ protocol development.
Is the centrifuge compatible with refrigerated operation?
No—the TDZ5-WS is a non-refrigerated model; ambient temperature operation only (10–32°C recommended).
