Overview
The AnTing TGL-18kR is a high-speed refrigerated benchtop centrifuge engineered for precision separation of biological, chemical, and pharmaceutical samples under controlled thermal conditions. Utilizing a brushless frequency-controlled motor and microprocessor-based speed regulation, the system delivers stable rotational performance across its operational range of 0–18,000 rpm, achieving a maximum relative centrifugal force (RCF) of 23,545 ×g. Its integrated refrigeration unit maintains sample temperature between −20 °C and +30 °C with ±2 °C accuracy—critical for preserving labile macromolecules such as nucleic acids, proteins, and organelles during high-G pelleting or density gradient fractionation. Designed for space-constrained laboratories, the compact footprint (600 × 460 × 365 mm) and 80 kg mass ensure mechanical stability without requiring floor-mounting, while the reinforced polymer chassis minimizes vibration transmission and supports long-term rotor balance integrity.
Key Features
- Brushless frequency-controlled motor for precise speed control, low maintenance, and extended service life
- Intuitive touchscreen interface with programmable protocols, real-time parameter display, and error diagnostics
- Active refrigeration system with independent compressor and PID temperature regulation for consistent thermal management
- Electronic door interlock with automatic rotor recognition and safety cutoff during lid opening or imbalance detection
- Five standardized fixed-angle rotor options supporting common microtube formats (1.5 mL, 5 mL, 7 mL, 10 mL), each calibrated for maximum RCF at specified speeds
- Timer range of 0–99 minutes with auto-brake and hold-at-end functionality for reproducible run termination
- Compliance-ready design: meets IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and ISO 13485-aligned manufacturing practices
Sample Compatibility & Compliance
The TGL-18kR accommodates standard polypropylene and polycarbonate microcentrifuge tubes (1.5–10 mL) and is routinely deployed in applications requiring adherence to GLP and GMP frameworks—including QC testing of biologics, clinical specimen processing, and raw material purification. While not certified for IVD use per FDA 21 CFR Part 820, its temperature logging capability (via optional external data logger integration), traceable rotor calibration records, and audit-trail-capable touchscreen firmware support internal validation protocols aligned with ISO/IEC 17025 requirements. All rotors are dynamically balanced per ISO 21501-4 and labeled with serial numbers and maximum speed/RCF ratings per ISO 15197 guidance for centrifuge documentation.
Software & Data Management
The embedded control firmware enables full protocol storage (up to 99 user-defined methods), including speed, temperature, time, acceleration/deceleration profiles, and rotor ID. Run logs—including start/stop timestamps, actual RCF achieved, peak temperature deviation, and fault codes—are retained onboard for ≥1,000 cycles. For regulatory environments, optional RS-232 or USB export allows transfer of CSV-formatted run records to LIMS or ELN systems. The interface supports password-protected administrator mode for parameter lockout, ensuring method consistency across shifts and operators—a prerequisite for USP analytical instrument qualification.
Applications
- Preparative isolation of plasmid DNA, genomic DNA, and RNA from lysates using silica-membrane or phenol-chloroform workflows
- Subcellular fractionation of mitochondria, lysosomes, and nuclei from mammalian tissue homogenates
- Clarification of bacterial and yeast cultures prior to protein expression analysis or metabolite extraction
- Concentration of viral particles and exosomes from cell culture supernatants or plasma derivatives
- Routine QC sedimentation of colloidal suspensions, nanoparticles, and polymer emulsions in materials science labs
- Stabilization of thermosensitive enzymes and antibodies during purification steps requiring cold-chain continuity
FAQ
What is the maximum allowable imbalance tolerance for safe operation?
The TGL-18kR is rated for ≤2 g imbalance per rotor position when loaded symmetrically; asymmetric loading beyond this threshold triggers immediate deceleration and error code E03.
Can the centrifuge maintain −20 °C during continuous 99-minute runs?
Yes—the refrigeration system is rated for sustained operation at −20 °C across the full timer range, provided ambient room temperature remains ≤25 °C and ventilation grilles are unobstructed.
Are rotor calibration certificates supplied with each unit?
Each rotor is factory-calibrated and shipped with a traceable certificate indicating nominal speed, RCF curve, and dynamic balance verification per ISO 21501-4 Annex B.
Is remote monitoring or network connectivity supported?
No native Ethernet or Wi-Fi module is included; however, the RS-232 port supports third-party SCADA integration via Modbus RTU protocol with appropriate interface converters.
Does the instrument comply with FDA 21 CFR Part 11 for electronic records?
The onboard system does not provide full Part 11 compliance (e.g., electronic signatures, audit trail encryption); users must implement supplementary validation and procedural controls to meet regulatory expectations.
