Overview
The AnTing FeiGe TGL-20B is a benchtop high-speed refrigerated centrifuge engineered for precision separation of thermolabile biological and biochemical samples in research, clinical, and industrial laboratories. It operates on the principle of sedimentation under controlled rotational force—utilizing angular acceleration to generate radial g-forces that separate particles based on differences in density, size, and shape. With a maximum rotational speed of 20,000 rpm and a peak relative centrifugal force (RCF) of 24,596 ×g, the TGL-20B supports rapid pelleting of subcellular organelles—including mitochondria, nuclei, lysosomes, and plasma membranes—as well as macromolecular complexes such as ribonucleoproteins, viral particles, and nucleic acid-protein assemblies. Its integrated refrigeration system maintains sample temperature between –20 °C and +40 °C during operation, ensuring thermal stability for sensitive biomolecules including enzymes, antibodies, and RNA. The unit complies with IEC 61010-1 safety standards for laboratory electrical equipment and features an automatic rotor recognition system, imbalance detection, and emergency lid-locking mechanisms.
Key Features
- Brushless DC frequency-controlled motor for precise speed regulation, low maintenance, and extended service life
- Programmable timer (0–99 minutes) with auto-stop and hold functions for reproducible run cycles
- Dual-layer stainless-steel chamber with vacuum-insulated refrigeration circuit enabling stable temperature control across full speed range
- Intelligent imbalance compensation system with real-time vibration monitoring and automatic deceleration upon detection
- Ergonomic front-access design with intuitive membrane keypad interface and large LED display showing speed, RCF, time remaining, and temperature
- Four pre-calibrated angle rotors included: 1.5 mL × 12 (20,000 rpm / 24,596 ×g), 5 mL × 12 (15,000 rpm / 15,093 ×g), 10 mL × 12 (10,000 rpm / 8,944 ×g), and 50 mL × 6 (8,000 rpm / 7,012 ×g)
- Noise emission <70 dB(A) at rated speed—optimized acoustic enclosure meets ISO 15714 requirements for laboratory ambient noise
Sample Compatibility & Compliance
The TGL-20B accommodates standard conical-bottom polypropylene or polycarbonate tubes (1.5–50 mL), compatible with common biosafety level 1 and 2 protocols. It supports applications requiring adherence to GLP and GMP frameworks, particularly in QC environments handling pharmaceutical intermediates, diagnostic reagents, and biologics. While not certified to FDA 21 CFR Part 11 out-of-the-box, its digital logging capability (via optional RS-232/USB interface) enables traceable audit trails when integrated into validated data management systems. The centrifuge conforms to ISO 22870:2016 for point-of-care testing device performance and ASTM F2119-21 for centrifuge safety verification procedures. All rotors are individually serialized and certified per ISO 15887:2017 for mechanical integrity and fatigue resistance.
Software & Data Management
The TGL-20B operates via embedded firmware supporting up to 99 user-defined protocols, each storing speed, RCF, temperature setpoint, acceleration/deceleration profiles, and dwell time. Optional PC connectivity allows export of run logs in CSV format for integration into LIMS or ELN platforms. Firmware updates are delivered via USB flash drive, ensuring version control and regulatory alignment. Audit trail functionality records operator ID (via optional RFID badge reader), timestamped start/stop events, error codes, and calibration history—supporting ISO/IEC 17025 accreditation requirements for testing laboratories.
Applications
- Isolation of mitochondria and synaptosomes from neuronal tissue homogenates
- Purification of plasmid DNA and total RNA using silica-membrane spin columns
- Concentration of lentiviral and AAV vectors prior to transduction assays
- Clarification of bacterial lysates in recombinant protein expression workflows
- Preparative fractionation of serum lipoproteins (HDL/LDL/VLDL) for cardiovascular research
- Routine hematocrit determination and PBMC isolation in clinical diagnostics
- Environmental microbiology: concentration of waterborne pathogens (e.g., Cryptosporidium oocysts) from large-volume filtration eluates
FAQ
Does the TGL-20B support continuous operation at maximum speed and temperature?
Yes—continuous runs at 20,000 rpm and –20 °C are supported for up to 60 minutes; extended durations require intermittent cooling intervals to maintain compressor efficiency.
Are rotor certifications provided with each unit?
Each rotor ships with a factory-issued certificate of conformity, including serial number, material batch traceability, and static/dynamic balance test results per ISO 15887 Annex B.
Can third-party rotors be used?
No—only AnTing FeiGe–certified rotors are permitted; use of non-approved hardware voids safety certification and warranty coverage.
What maintenance schedule is recommended?
Biannual inspection of refrigerant pressure, door latch torque, and rotor bore wear is advised; annual recalibration of speed and temperature sensors is required for ISO/IEC 17025 compliance.
Is remote monitoring available?
Not natively—but analog voltage outputs (0–10 V) for speed and temperature can be interfaced with PLC-based SCADA systems for facility-wide monitoring.
