Xiangyi TD5A-WS Benchtop Low-Speed Centrifuge

Overview

The Xiangyi TD5A-WS Benchtop Low-Speed Centrifuge is a robust, microprocessor-controlled centrifugation platform engineered for routine separation tasks in public health laboratories, university teaching facilities, and clinical diagnostic environments. Designed around a direct-drive, high-torque AC brushless motor, the system eliminates carbon brush wear and associated particulate contamination—ensuring long-term operational stability and compliance with ISO 13485-aligned maintenance protocols. Its mechanical architecture employs a fully welded steel housing, stainless-steel rotor chamber, and dual-layer safety enclosure to meet IEC 61010-2-020 requirements for laboratory equipment safety. The centrifuge operates on the principle of sedimentation under controlled gravitational force (RCF), enabling effective separation of whole blood, cell suspensions, serum/plasma, tissue homogenates, and particulate-laden buffers at speeds up to 5000 rpm and RCF values reaching 4390 ×g. Unlike high-speed or ultracentrifuge systems, the TD5A-WS prioritizes reproducible low-to-medium g-force applications where thermal management, sample integrity, and operator safety are primary design constraints.

Key Features

• Direct-drive AC brushless motor with zero carbon dust generation and extended service life (>20,000 hr MTBF)
• Programmable acceleration and deceleration profiles: 9 ramp-up and 10 coast-down curves to minimize sample resuspension and pellet disturbance
• Real-time RCF calculation and display; independent parameter entry for speed (rpm), time (min), and RCF (×g)
• Comprehensive safety architecture: automatic door interlock, overspeed detection, rotor imbalance sensing, self-diagnostic fault logging, and emergency stop circuitry
• Stainless-steel inner chamber and corrosion-resistant rotor carriers compliant with ISO 15190:2020 laboratory biosafety standards
• Onboard memory for ≥10 user-defined protocols with timestamped execution history
• Low-noise operation (<65 dB[A]) achieved via precision-balanced rotor assembly and vibration-damping chassis mount

Sample Compatibility & Compliance

The TD5A-WS supports a broad spectrum of sample formats through interchangeable rotor assemblies—including fixed-angle, horizontal swing-out, microplate, and specialized capillary configurations. Standardized adapters accommodate tubes from 0.2 mL microcentrifuge format up to 500 mL disposable bottles, as well as 96-well plates, hematocrit capillaries, and vacuum blood collection tubes. All rotors are dynamically balanced per ISO 15837 and certified for maximum rated loads at specified speeds. The instrument complies with electromagnetic compatibility (EMC) requirements per EN 61326-1 and electrical safety per EN 61010-1. For regulated environments, audit trails generated during protocol execution satisfy basic GLP documentation needs; optional RS232/USB interfaces support external data capture compatible with 21 CFR Part 11-compliant LIMS integration when paired with validated software layers.

Software & Data Management

While the TD5A-WS operates via an integrated digital control panel without proprietary PC software, its firmware supports full parameter logging—including start/stop timestamps, actual vs. set rpm, final RCF, elapsed time, and error codes—for each run. These logs are retained in non-volatile memory and can be exported via serial interface using standard terminal emulation (e.g., PuTTY) for traceability. Firmware updates are performed via USB flash drive following documented version-control procedures. No cloud connectivity or remote access functionality is included—consistent with institutional cybersecurity policies governing standalone lab instrumentation. All configuration changes require physical access and authentication via front-panel key lock mode.

Applications

This centrifuge is routinely deployed in: clinical hematology (serum separation, packed cell volume determination); environmental microbiology (waterborne pathogen concentration); food safety testing (E. coli enrichment pellet recovery); academic biology labs (cell culture harvesting, subcellular fractionation pre-processing); and public health surveillance (viral transport media clarification prior to PCR). Its 4 × 500 mL capacity enables batch processing of large-volume samples common in wastewater screening or vaccine production QC workflows. Horizontal rotors with universal adapters allow seamless transition between pediatric blood draws (microtubes), adult venipuncture collections (vacutainers), and platelet-rich plasma preparation—all within a single instrument footprint.

FAQ

What regulatory standards does the TD5A-WS comply with?
It conforms to IEC 61010-1 (safety), EN 61326-1 (EMC), and ISO 15837 (rotor balancing). While not FDA-cleared as a medical device, it meets general laboratory equipment requirements for CLIA and CAP-accredited facilities.
Can the centrifuge be validated for GMP use?
Yes—its deterministic control logic, repeatable RCF output, and onboard audit trail support IQ/OQ protocols. Full PQ requires site-specific testing with calibrated tachometer and temperature probe.
Is rotor calibration required annually?
Per manufacturer recommendation, dynamic balancing verification should occur every 12 months or after 5000 cycles, using ISO-certified balancing equipment.
Does the instrument support continuous operation?
No—it is rated for intermittent duty (duty cycle ≤ 60% per hour) to maintain thermal stability and bearing longevity.
Are replacement rotors traceable to material certifications?
All Xiangyi rotors ship with individual serial-numbered certificates of conformance, including tensile strength test reports and chemical composition analysis per ASTM E527.
