TGL-20M / TGL-20MS High-Speed Refrigerated Centrifuge

Overview

The TGL-20M and TGL-20MS are high-speed refrigerated centrifuges engineered for precision separation of biological, clinical, and chemical samples in demanding laboratory environments. Designed around a robust horizontal-axis rotor architecture and compliant with ISO 21501-4 and IEC 61010-1 safety standards, these instruments employ fixed-angle and swing-bucket rotor configurations to deliver reproducible sedimentation forces across diverse sample volumes and densities. The core operational principle relies on controlled angular acceleration and deceleration profiles—governed by vector-controlled brushless frequency-conversion motors—to generate centrifugal fields up to 27,800 × g. Integrated refrigeration uses environmentally compliant R-404A refrigerant and imported compressor modules, maintaining thermal stability within ±1 °C across the full operating range (−20 °C to +40 °C). Both models support real-time conversion between rotational speed (RPM) and relative centrifugal force (RCF), enabling method transfer consistency across global laboratories adhering to CLSI GP45-A4 or USP centrifugation protocols.

Key Features

• Microprocessor-based control system with large-backlit LCD (TGL-20MS) or high-contrast digital display (TGL-20M), supporting multi-language UI and intuitive touch-panel operation
• Automatic rotor recognition via embedded RFID tags—eliminating manual rotor ID entry and preventing mismatched speed/temperature parameter loading
• Brushless DC motor with high-torque output and zero-maintenance design; certified for ≥20,000 h MTBF under continuous duty cycles
• Programmable acceleration/deceleration profiles: 10 pre-stored ramp curves with independent slope control for sensitive pelleting or gradient preservation
• Comprehensive safety architecture: active imbalance detection with automatic shutdown, electromagnetic door interlock, overspeed cutoff, overtemperature lockout, and real-time rotor fatigue monitoring
• Non-volatile memory stores all run parameters—including rotor ID, speed, temperature, time, and RCF—for audit-ready traceability and GLP-compliant record retention

Sample Compatibility & Compliance

The TGL-20M/20MS accommodates standard laboratory consumables including polypropylene conical tubes (1.5–10 mL), PCR strips, microcentrifuge tubes, and 96-well microplates (via swing-bucket configuration). Its rotor portfolio meets ISO 15195:2019 requirements for calibration traceability and supports validation per ASTM E2500-13 (Good Practice for Verification and Validation of Analytical Instruments). All refrigeration components comply with EU F-Gas Regulation (EU) No 517/2014 and EPA SNAP Program criteria for low-global-warming-potential (GWP) refrigerants. Electrical safety conforms to IEC 61010-2-020 for laboratory centrifuges, and mechanical integrity is verified per ISO 13485:2016 Annex C for medical device manufacturing environments.

Software & Data Management

While standalone operation is fully functional, optional PC connectivity (RS-232 or USB) enables remote configuration and data export in CSV or XML format. Audit trails include timestamped event logs (e.g., door open/close, rotor load/unload, error codes), meeting FDA 21 CFR Part 11 requirements when paired with validated third-party LIMS integration. Method templates can be exported/imported for cross-instrument protocol harmonization—critical for QC labs performing ISO/IEC 17025:2017 accredited testing. All stored methods retain full metadata: operator ID, calibration date, rotor serial number, and environmental conditions at time of execution.

Applications

These centrifuges serve critical roles in molecular biology (nucleic acid extraction, plasmid purification), clinical diagnostics (serum/plasma separation, PBMC isolation), pharmaceutical development (nanoparticle pelleting, liposome formulation), and industrial quality control (polymer dispersion analysis, catalyst recovery). The TGL-20MS’s enhanced thermal management supports extended runs at sub-zero temperatures required for enzyme stability studies, while the TGL-20M’s simplified interface suits routine QA workflows in GMP-regulated manufacturing facilities. Both models support gradient centrifugation protocols for density-based fractionation (e.g., sucrose, iodixanol) and are routinely deployed in ISO 13485-certified IVD production lines.

FAQ

What rotor types are included as standard equipment?
The base configuration includes five rotors: three fixed-angle (1.5 mL × 12, 1.5 mL × 24, 5 mL × 10) and two swing-bucket (2 × 48-well plate, 10 mL × 8). Additional rotors—including carbon-fiber variants and custom adapters—are available under separate part numbers.
Is the refrigeration system serviceable in-field?
Yes—the R-404A circuit employs modular compressor and condenser assemblies compatible with standard HVAC-R service tools; field replacement kits and OEM technical bulletins are provided with each unit.
How is rotor lifetime tracked and managed?
Each rotor contains an embedded EEPROM storing cumulative run hours, maximum speed history, and thermal cycling count; this data is automatically read and logged during every centrifuge startup.
Can the instrument be integrated into a networked lab environment?
Via optional Ethernet module (TGL-NET-01), units support DHCP-assigned IP addressing, SNMP v3 monitoring, and secure TLS 1.2 encrypted data transmission to central lab informatics platforms.
Does the system support IQ/OQ/PQ documentation packages?
Yes—comprehensive qualification templates aligned with ASTM E2500-13 and EU Annex 15 are supplied with purchase, including blank forms, test scripts, and acceptance criteria for installation, operational, and performance qualification.
