Overview
The LuXiangYi TD4A Benchtop Low-Speed Centrifuge is an engineered solution for routine sedimentation, clarification, and pelleting applications in clinical, academic, and quality control laboratories. Designed around the principles of fixed-angle centrifugation, it delivers consistent separation performance for biological samples including whole blood, cell suspensions, urine sediments, and coarse particulates—without requiring ultracentrifugal forces or refrigerated operation. Its mechanical architecture prioritizes operational stability at moderate rotational speeds (up to 4000 rpm), minimizing vibration transmission and ensuring reproducible pellet formation across repeated runs. The unit complies with IEC 61010-1:2010 safety standards for laboratory electrical equipment and incorporates dual-layer mechanical and electronic safeguards—including a lid interlock system that halts rotation immediately upon lid opening—to meet GLP-aligned operational safety requirements.
Key Features
- Industrial-grade ABS polymer housing: Chemically resistant, impact-tough, and non-porous for easy decontamination and long-term durability in multi-user lab environments.
- Intelligent parameter retention: Automatically stores the last-used speed and time settings, reducing setup time between consecutive runs and supporting standardized operating procedures (SOPs).
- Low-noise operation (<65 dB[A] at full speed): Achieved via precision-balanced rotor assembly, optimized airflow design, and vibration-damping base construction—critical for shared lab spaces and noise-sensitive facilities.
- Programmable digital timer: Adjustable from 1 to 60 minutes with auto-stop functionality; supports both timed and continuous modes for flexibility in protocol adaptation.
- Integrated rotor recognition logic: Ensures safe operation only when certified fixed-angle rotors are correctly seated—preventing mismatched rotor usage and associated imbalance risks.
- Compact footprint (320 × 410 × 320 mm): Optimized for benchtop deployment in space-constrained labs without compromising structural rigidity or thermal dissipation capacity.
Sample Compatibility & Compliance
The TD4A accommodates common clinical and research sample formats using four interchangeable fixed-angle rotors: 12 × 15 mL, 6 × 50 mL, 8 × 20 mL, and 6 × 15 mL conical tubes. All rotors are manufactured from high-strength aluminum alloy (6061-T6) and certified for maximum angular acceleration up to 4000 rpm under full-load conditions. The centrifuge meets ISO 13485-aligned manufacturing controls for medical device accessories and conforms to EN 61326-1:2013 for electromagnetic compatibility (EMC). It supports traceability in regulated workflows through manual logbook integration and is compatible with laboratory information management systems (LIMS) via external documentation of run parameters (speed, time, rotor ID, date/time stamp).
Software & Data Management
The TD4A operates via a dedicated microcontroller-based interface with LED display and tactile membrane keypad—designed for reliability in glove-compatible, high-hygiene environments. While it does not include onboard data logging or USB connectivity, its deterministic control logic ensures repeatable parameter execution across shifts and operators. For audit readiness, users may document each run manually or integrate with external electronic lab notebooks (ELNs) compliant with FDA 21 CFR Part 11 requirements. Firmware updates are performed offline via manufacturer-provided service tools; no internet connection is required during operation, enhancing cybersecurity posture in network-isolated labs.
Applications
- Routine serum/plasma separation from whole blood specimens in clinical diagnostics labs.
- Pelleting of mammalian and microbial cells prior to lysis or RNA/DNA extraction protocols.
- Sedimentation of urinary casts, crystals, and cellular debris in urinalysis workflows.
- Clarification of crude protein extracts, tissue homogenates, and fermentation broths in bioprocessing QC.
- Preparative isolation of extracellular vesicles (e.g., microvesicles) where high g-force-induced aggregation must be avoided.
- Centrifugal washing steps in ELISA plate preparation and lateral flow assay development.
FAQ
What is the maximum relative centrifugal force (RCF) achievable with the TD4A?
The TD4A achieves a maximum RCF of 2760 × g at 4000 rpm with the 50 mL × 6 rotor.
Does the TD4A support refrigerated operation?
No—the TD4A is a non-refrigerated centrifuge intended for ambient-temperature separations only.
Can I use swing-bucket rotors with this model?
No—only the four specified fixed-angle rotors (15 mL × 12, 50 mL × 6, 20 mL × 8, 15 mL × 6) are mechanically and electronically validated for use.
Is the unit compliant with international electrical safety standards?
Yes—it complies with IEC 61010-1:2010 and EN 61326-1:2013 for laboratory electrical equipment and EMC.
How is rotor imbalance detected and mitigated?
The TD4A employs mechanical imbalance sensing via load-responsive motor current monitoring and automatically halts operation if excessive vibration exceeds threshold limits during acceleration.
