LuXiangYi TD5A-WS Benchtop Low-Speed Centrifuge

Overview

The LuXiangYi TD5A-WS is a microprocessor-controlled, benchtop low-speed centrifuge engineered for routine separation tasks in clinical laboratories, biotechnology facilities, and academic research settings. It operates on a brushless DC motor architecture—ensuring mechanical longevity, minimal thermal drift, and consistent rotational stability across extended duty cycles. Unlike high-speed or ultracentrifuges designed for subcellular fractionation, the TD5A-WS is optimized for applications requiring gentle yet reliable sedimentation of whole cells, precipitated proteins, erythrocytes, platelets, and other particulates with sedimentation coefficients in the range typical of biological macromolecules (e.g., immunoglobulins, lipoproteins, and viral particles). Its horizontal rotor configuration supports standardized tube geometries and ensures uniform force distribution during acceleration and deceleration phases—critical for reproducible pellet formation and sample integrity.

Key Features

• Brushless DC motor drive delivering quiet operation (10,000 operational hours.
• Intuitive touch-panel interface with LCD display enabling real-time switching between rpm and RCF values, eliminating manual conversion errors during protocol setup.
• Programmable memory function storing up to 10 user-defined protocols—including speed, time, and acceleration/deceleration profiles—for rapid recall and inter-operator consistency.
• Integrated electronic door lock with automatic lid interlock, overspeed protection, imbalance detection, and fault diagnostics—compliant with IEC 61010-1 safety standards for laboratory equipment.
• Precision speed control with ±50 rpm accuracy across the full 0–5000 rpm range, validated per ISO 15195:2019 guidelines for centrifuge calibration traceability.
• Thermally insulated chamber design minimizing ambient heat transfer to samples during prolonged runs.

Sample Compatibility & Compliance

The TD5A-WS accommodates a broad range of standard centrifuge vessels via interchangeable rotors and adapters—including 15 mL conical tubes (36-position), 50 mL tubes (4- or 8-position), 100 mL bottles (4-position), 7 mL microtubes (72-position), and 96-well microplates (8-position). All rotors are dynamically balanced and certified to ISO 21501-4 for particle size distribution validation. The instrument meets essential regulatory prerequisites for GLP-compliant environments: audit-trail-capable parameter logging (via optional RS232/USB data export), timer-based run termination, and non-volatile memory retention of operational history. While not FDA 21 CFR Part 11–certified out-of-the-box, its firmware architecture supports third-party validation packages required for GMP-aligned quality control labs processing pharmaceutical intermediates or diagnostic reagents.

Software & Data Management

The TD5A-WS operates autonomously without external software dependencies; however, its embedded controller supports ASCII-formatted runtime logs exported via USB or serial interface. These logs include timestamped entries for start/stop times, setpoints, actual speed/RCF, detected faults, and door status—enabling integration into LIMS platforms using custom parsing scripts. Optional PC-based configuration tools (provided by BIORIDGE) allow batch programming of multi-step protocols, remote monitoring via Ethernet (with add-on module), and export of CSV-formatted compliance reports aligned with ISO/IEC 17025 documentation requirements.

Applications

• Clinical hematology: Separation of whole blood into plasma, buffy coat, and packed red cells using standardized 15 mL or 50 mL tubes.
• Cell culture harvest: Gentle pelleting of adherent or suspension mammalian cells at ≤4390 × g to preserve membrane integrity prior to lysis or cryopreservation.
• Diagnostic assay preparation: Clarification of serum, urine, or cerebrospinal fluid specimens prior to ELISA, PCR, or immunoassay workflows.
• Food & environmental testing: Sedimentation of suspended solids from milk, juice, or wastewater samples in accordance with AOAC 984.27 and ISO 7218 protocols.
• Educational laboratories: Teaching core principles of sedimentation kinetics, rotor dynamics, and centrifugal force calculation under controlled, repeatable conditions.

FAQ

What is the maximum relative centrifugal force (RCF) achievable with the TD5A-WS?

The instrument delivers a verified maximum RCF of 4390 × g when operating at 5000 rpm with the 50 mL × 4 rotor.
Does the TD5A-WS support rotor auto-recognition?

No—rotor identification is manual; users must select the appropriate rotor profile from the menu to ensure accurate RCF calculation and safety limits.
Can the centrifuge be used for continuous operation over multiple cycles?

Yes—its brushless motor and passive cooling system permit uninterrupted sequential runs, provided the cumulative duty cycle does not exceed 80% per hour to maintain thermal stability.
Is calibration documentation included with shipment?

A factory-issued calibration certificate (traceable to NIM, China) is supplied, covering speed, timer, and temperature (if equipped); field recalibration services are available through authorized BIORIDGE service centers.
Are rotors supplied with CE marking for use in EU laboratories?

All standard rotors carry CE marking under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), with conformity assessment performed by SGS Shanghai.
