Overview
The AnTing TDL-5000bR is a benchtop low-speed refrigerated centrifuge engineered for routine separation tasks in clinical laboratories, biotechnology facilities, and academic research environments. It operates on the principle of sedimentation under controlled gravitational force—generating up to 5000 × g at its maximum rotational speed of 5000 rpm—to separate heterogeneous mixtures based on particle density, size, and shape. Unlike high-speed or ultracentrifuges designed for subcellular fractionation, the TDL-5000bR is optimized for applications requiring gentle yet effective pelleting of cells, precipitates, and large particulates without compromising structural integrity. Its integrated refrigeration system maintains sample temperature between −20 °C and +30 °C, ensuring thermal stability during extended runs—a critical requirement for heat-sensitive biological samples such as plasma, serum, whole blood, tissue homogenates, and polymer suspensions.
Key Features
- Refrigerated operation with precise temperature control (±2 °C accuracy) across a wide range from −20 °C to +30 °C, supporting both cryogenic and ambient-temperature protocols.
- Benchtop footprint (720 × 540 × 460 mm) designed for space-constrained laboratory environments while maintaining structural rigidity and vibration damping.
- Swing-bucket rotor configuration supporting multiple tube formats: 250 mL × 4, 50 mL × 8, or 10 mL × 36—all rated for full-speed operation at 5000 rpm and 5000 × g.
- Optional secondary swing-bucket rotor accommodating up to 96 × 6 mL tubes at 4000 rpm, ideal for high-throughput clinical sample processing.
- Electronic door interlock system prevents operation unless the lid is fully closed and secured, complying with IEC 61010-1 safety standards for laboratory equipment.
- Low-noise design (<70 dB[A]) achieved through balanced rotor dynamics, acoustic insulation, and brushless DC motor technology—reducing ambient acoustic load in shared lab spaces.
- Digital timer with programmable range from 0 to 99 minutes enables reproducible run durations essential for standardized SOP execution.
Sample Compatibility & Compliance
The TDL-5000bR accommodates common laboratory consumables including polypropylene conical tubes (10–250 mL), glass centrifuge bottles, and standard microtiter plate carriers. Its rotor geometry ensures uniform radial distribution of g-force and minimal shear stress, preserving viability of mammalian cells and integrity of protein aggregates. The unit meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. While not certified for GMP or GLP environments out-of-the-box, its operational repeatability, temperature logging capability (when paired with external data loggers), and electronic access control support alignment with ISO/IEC 17025 quality management systems for testing laboratories.
Software & Data Management
The TDL-5000bR features an embedded microprocessor-based controller with LED display and membrane keypad interface. All operational parameters—including speed, time, temperature, and rotor identification—are stored in non-volatile memory and can be recalled for repeat protocols. Though it does not include built-in USB or Ethernet connectivity, the system supports manual audit trail generation via printed parameter logs (when interfaced with optional thermal label printers). For laboratories operating under FDA 21 CFR Part 11 requirements, integration with third-party LIMS platforms is achievable using analog signal outputs or RS-232 serial communication modules (available as accessories).
Applications
- Clinical diagnostics: Separation of serum/plasma from whole blood; preparation of buffy coats; isolation of urinary sediments.
- Cell culture workflows: Harvesting adherent and suspension cells prior to lysis or cryopreservation.
- Pharmaceutical QA/QC: Clarification of suspensions, emulsions, and coarse dispersions during formulation development.
- Environmental testing: Sedimentation of soil extracts, wastewater particulates, and algae cultures.
- Food & beverage analysis: Fat separation in milk homogenates, yeast removal from fermentation broths, and starch granule isolation.
FAQ
What is the maximum relative centrifugal force (RCF) achievable with this centrifuge?
The TDL-5000bR delivers a maximum RCF of 5000 × g at 5000 rpm with the standard 250 mL swing-bucket rotor.
Can the centrifuge maintain −20 °C during continuous operation?
Yes—the refrigeration system is rated for sustained operation at −20 °C, provided ambient room temperature remains ≤25 °C and ventilation clearances are maintained per installation guidelines.
Is rotor imbalance detection included?
The unit incorporates mechanical imbalance sensing that automatically decelerates and halts rotation if excessive vibration is detected during acceleration or steady-state operation.
Does the TDL-5000bR comply with ISO 13485 or FDA 21 CFR Part 11?
It is not pre-certified for these regulatory frameworks; however, its design supports traceability and procedural consistency when deployed within validated laboratory workflows.
What maintenance intervals are recommended?
Routine inspection of door seals, rotor threads, and refrigerant lines is advised every 6 months; annual calibration of temperature and speed sensors is recommended for ISO/IEC 17025-compliant labs.
