Overview
The Xiangyi TDZ5-WS is a robust, microprocessor-controlled benchtop low-speed centrifuge engineered for routine separation tasks in clinical laboratories, blood banks, and quality control environments. It operates on the principle of sedimentation under gravitational force enhanced by rotational acceleration—generating relative centrifugal force (RCF) to separate components based on density differentials in heterogeneous liquid samples. Designed specifically for applications requiring gentle yet reliable pelleting—such as whole blood fractionation, cell harvesting, urine sediment analysis, and serum/plasma preparation—the TDZ5-WS delivers stable performance at speeds up to 5000 rpm and maximum RCF of 4390 × g. Its horizontal swing-out rotor architecture ensures uniform sample distribution during acceleration and deceleration, minimizing mechanical stress on tubes and preserving sample integrity.
Key Features
- DC brushless motor drive system eliminates carbon brushes, ensuring long service life, low electromagnetic interference, and maintenance-free operation over extended duty cycles.
- Automatic rotor balancing mechanism compensates for minor mass imbalances across the four-position swing-out rotor, enabling safe operation even with partially loaded configurations.
- Integrated electronic lid lock prevents accidental opening during rotation, complying with IEC 61010-2-020 safety requirements for laboratory centrifuges.
- Full steel monocoque chassis provides structural rigidity, vibration damping, and impact resistance—critical for stability during high-load runs and transport between lab stations.
- Intuitive digital interface with real-time display of speed (rpm), RCF (× g), remaining time (down to 1-second resolution), and acceleration/deceleration status.
- Programmable timer with rapid ramp-down (<60 s) minimizes thermal buildup in temperature-sensitive biological specimens and supports high-throughput workflow continuity.
Sample Compatibility & Compliance
The TDZ5-WS accommodates a wide range of standard clinical tube formats via interchangeable adapters: up to 32 × 15 mL conical tubes, 16 × 50 mL conical tubes, or 64 × 5–7 mL vacuum collection tubes (e.g., EDTA, heparin, serum separator tubes). All rotor assemblies are precision-balanced and certified for use within ISO 13485-certified manufacturing processes. While not refrigerated, the unit meets GLP-aligned operational standards for non-critical sample processing where ambient-temperature stability is acceptable. It conforms to key electrical safety directives including IEC 61010-1 and EMC compliance per IEC 61326-1, supporting integration into regulated environments under internal SOPs.
Software & Data Management
This model operates without external software dependency—control logic resides entirely in embedded firmware with non-volatile memory for storing up to 10 user-defined protocols. Each protocol retains independent settings for speed, time, and RCF; parameters are recalled with one-touch selection. Though it lacks USB or Ethernet connectivity, its digital audit trail includes timestamped run logs accessible via front-panel navigation—supporting basic traceability requirements for ISO/IEC 17025-compliant labs performing routine QC checks. For full 21 CFR Part 11 compliance, integration with third-party LIMS platforms may be achieved through RS-232 serial output (optional accessory).
Applications
- Clinical diagnostics: Separation of serum, plasma, and cellular fractions from whole blood specimens prior to immunoassay, hematology, or coagulation testing.
- Pharmaceutical QA/QC: Clarification of suspension-based formulations, particulate removal from ophthalmic solutions, and excipient compatibility screening.
- Academic research: Harvesting mammalian or bacterial cells at low g-forces to maintain membrane integrity and viability pre-lysis.
- Environmental testing labs: Solid-liquid phase separation in wastewater sludge analysis or soil extract clarification.
- Veterinary practice: Rapid processing of animal blood and tissue homogenates for point-of-care diagnostics.
FAQ
Is the TDZ5-WS suitable for centrifuging infectious or biohazardous samples?
Yes—when used with sealed, leak-proof tubes and appropriate biosafety cabinets, its fully enclosed steel housing and interlocked lid meet BSL-2 containment expectations for routine handling.
Can I upgrade this unit with a refrigeration module?
No—the TDZ5-WS is a non-refrigerated platform; Xiangyi offers separate refrigerated variants (e.g., TDZ5R series) for temperature-sensitive applications.
What certifications does this model carry?
It bears CE marking per Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU, along with RoHS 2011/65/EU compliance documentation.
How often does the rotor require calibration or certification?
Rotors are factory-calibrated and do not require periodic recalibration; however, visual inspection for corrosion or deformation should occur before each use per manufacturer’s maintenance guidelines.
Does the unit support continuous operation mode?
No—it is designed for batch processing only; the maximum recommended run duration per cycle is 60 minutes to ensure thermal management and bearing longevity.
