Overview
The LUXIANGYI TD-6K Benchtop Microcentrifuge is an engineered solution for routine low-speed separation tasks in life science laboratories, clinical diagnostics, and educational settings. Designed around a brushless DC motor architecture, it delivers stable rotational performance without carbon brushes or scheduled maintenance—ensuring long-term operational consistency and reduced downtime. Its operating principle relies on centrifugal force generation via controlled angular acceleration, enabling sedimentation of suspended particles—including whole cells, bacteria, and precipitated macromolecules—within micro-volume tubes. With a maximum speed of 6000 rpm and a corresponding relative centrifugal force (RCF) of 2000 × g, the TD-6K falls within the low-speed centrifugation range defined by ISO 15195:2019 for routine sample preparation prior to downstream analysis (e.g., ELISA, PCR setup, or buffer exchange). Its compact footprint and silent operation (<48 dB[A]) make it suitable for shared lab benches, biosafety cabinets, and point-of-care environments where acoustic comfort and spatial efficiency are critical.
Key Features
- Brushless DC motor with integrated thermal protection and electronic speed regulation for consistent torque delivery across load conditions
- Patented electrostatic shielding design minimizes electromagnetic interference and contributes to ultra-low acoustic emission during operation
- Intuitive push-button interface with real-time rpm/RCF dual-display and programmable run time (1 s to 99 min 59 s)
- Automatic rotor identification logic prevents overspeeding; rotor lock mechanism ensures mechanical safety during acceleration/deceleration
- Compact monocoque chassis constructed from reinforced ABS polymer and aluminum alloy housing for vibration damping and structural integrity
- Compliance with IEC 61010-1:2010 safety standards for laboratory electrical equipment, including protection against electric shock, mechanical hazards, and abnormal temperature rise
Sample Compatibility & Compliance
The TD-6K accommodates standard microcentrifuge tube formats—specifically six positions for 0.2 mL, 0.5 mL, or 1.5 mL conical or round-bottom polypropylene tubes—without requiring adapters. It supports balanced loading configurations only, in accordance with CLSI EP15-A3 guidelines for centrifuge validation. While not certified for biosafety level (BSL)-3 or BSL-4 applications, its sealed rotor chamber meets ISO 13485:2016 requirements for non-sterile medical device accessory classification. The unit is compatible with common reagent-grade solvents (e.g., ethanol, isopropanol, aqueous buffers) and does not require special containment for routine nucleic acid or protein pellet recovery workflows. All materials in contact with samples comply with USP Class VI biocompatibility testing criteria.
Software & Data Management
As a standalone benchtop instrument, the TD-6K operates without proprietary software or external connectivity. However, its embedded firmware supports audit-ready parameter logging—including start time, final speed, actual RCF achieved, and elapsed runtime—for manual GLP documentation. Users may record these values directly into laboratory notebooks or LIMS-compatible spreadsheets. Though lacking USB/Ethernet interfaces or FDA 21 CFR Part 11-compliant electronic signatures, the device satisfies basic traceability requirements under ISO/IEC 17025:2017 clause 7.7 for equipment usage records in accredited testing laboratories.
Applications
- Routine pelleting of bacterial cultures (E. coli, Bacillus spp.) and mammalian cell lines (HEK293, CHO-K1) at early-log phase
- Clarification of lysates prior to SDS-PAGE or Western blotting sample loading
- Recovery of DNA/RNA pellets following alcohol precipitation protocols (e.g., sodium acetate/isopropanol method)
- Separation of serum from whole blood in point-of-care hematology screening
- Centrifugal concentration of dilute antibody solutions or enzyme preparations in teaching labs
- Pre-analytical processing of environmental water samples for microbial enumeration (ISO 9308-1)
FAQ
What is the maximum allowable imbalance tolerance for safe operation?
The TD-6K requires symmetrical loading across all six positions; no single-tube operation is permitted. Maximum permissible mass difference between opposing tubes is ±0.1 g.
Can this centrifuge be used with PCR strip tubes?
Yes—when using the optional 0.2 mL adapter block (sold separately), the TD-6K supports 8-strip PCR tubes in two parallel rows of four positions each.
Is rotor calibration required before first use?
No. The rotor is factory-balanced and certified per ISO 15195 Annex B. Users should verify physical integrity (no cracks, deformation, or corrosion) before each use.
Does the unit support continuous-run mode?
No. The TD-6K operates in timed mode only, with automatic deceleration and brake engagement upon completion.
What maintenance is recommended for long-term reliability?
Wipe exterior surfaces with 70% isopropyl alcohol after each use; inspect rotor threads and lid latch monthly; avoid exposure to halogenated solvents or strong oxidizers.
