Overview
The LUXIANGYI TD-10k is a compact, high-speed benchtop centrifuge engineered for precision microsample separation in resource-constrained or space-limited laboratory environments—including biosafety cabinets, clean benches, and mobile diagnostic units. It operates on the principle of radial acceleration to sediment particles based on size, density, and medium viscosity—enabling rapid pelleting of nucleic acids, cellular organelles, precipitated proteins, and micro-volume clinical specimens. With a maximum rotational speed of 10,000 rpm and an achievable relative centrifugal force (RCF) of 5,000 × g, the TD-10k delivers reproducible separation performance within standardized microtube formats without requiring refrigeration or vacuum enclosures. Its brushless DC motor eliminates carbon brush wear, ensuring long-term torque stability and consistent speed control across repeated duty cycles—a critical requirement for method transfer between QC labs and multi-site clinical workflows.
Key Features
- Ultra-compact footprint (189 × 161 × 122 mm) optimized for integration into laminar flow hoods and modular lab benches.
- Brushless DC motor with integrated thermal protection and soft-start/soft-stop ramping to minimize sample disturbance and rotor stress.
- Patented electrostatic shielding reduces electromagnetic interference and contributes to acoustic noise suppression below 48 dB(A) at full speed—meeting ISO 15703:2018 ambient noise guidelines for quiet-zone laboratories.
- Dual-position microtube rotor configuration supporting two parallel rows of eight 0.2 mL PCR tubes (0.2 mL × 2 × 8), enabling high-throughput nucleic acid purification in minimal bench space.
- Real-time RPM and RCF display with manual speed adjustment in 100-rpm increments; no programmable time or acceleration/deceleration profiles—designed for simplicity and operational robustness.
- Self-balancing rotor system with mechanical lock detection and automatic shutdown upon imbalance detection (>±0.5 g mass differential per side).
Sample Compatibility & Compliance
The TD-10k accommodates standard thin-walled polypropylene 0.2 mL PCR tubes (including skirted and non-skirted variants) and is compatible with common molecular biology reagents including ethanol, isopropanol, guanidine thiocyanate, and chaotropic salt buffers. While not certified under IEC 61010-2-020 for Class II biological safety applications, its enclosure meets IP20 ingress protection standards and conforms to general electrical safety requirements aligned with EN 61010-1. The device supports documentation practices compliant with GLP (Good Laboratory Practice) and basic GMP traceability when paired with lab notebook entries or LIMS-integrated logging of run parameters (speed, duration, date/time). It does not support 21 CFR Part 11 electronic signature functionality or audit-trail generation natively.
Software & Data Management
The TD-10k operates as a standalone instrument with no embedded firmware-based data storage, network interface, or USB connectivity. All operational parameters are set manually via front-panel controls and displayed in real time on a dual-digit LED screen. No proprietary software, drivers, or cloud services are required—or supported—for routine use. This architecture minimizes cybersecurity exposure, avoids firmware update dependencies, and ensures uninterrupted operation in low-infrastructure settings such as field clinics or teaching laboratories. Users are expected to record run conditions externally using paper logs or institutional LIMS platforms.
Applications
- Routine pelleting of DNA/RNA from silica-membrane spin columns during kit-based extractions.
- Clarification of small-volume enzymatic reaction mixtures prior to electrophoresis or spectrophotometric analysis.
- Separation of bacterial lysates in plasmid miniprep workflows where high RCF is needed but refrigeration is unnecessary.
- Microcentrifugation of immunoassay reagents, antibody conjugates, and nanoparticle suspensions in assay development labs.
- Student training in fundamental centrifugation principles—ideal for undergraduate biotechnology and medical technology curricula due to intuitive operation and mechanical reliability.
FAQ
Is the TD-10k suitable for use with infectious or biohazardous samples?
No—this model lacks sealed rotor containment, aerosol-tight lid interlocks, or biosafety certification. It must only be operated with non-pathogenic, non-aerosolizing samples in accordance with local biosafety level (BSL-1) protocols.
Can the rotor accommodate 1.5 mL tubes?
No—the standard rotor is configured exclusively for 0.2 mL PCR tubes in a dual-row layout (0.2 mL × 2 × 8). Alternate rotors for larger tube formats are not available for this model.
Does the centrifuge include a timer function?
No—the TD-10k is a continuous-run device without built-in timing circuitry. Users must monitor run duration externally using wall clocks or stopwatch functions.
What maintenance is required for the brushless motor?
None—the motor contains no consumable parts and requires no lubrication, cleaning, or periodic calibration over its service life.
Is calibration documentation provided with the unit?
No factory calibration certificate is included. Users performing regulated work should validate speed accuracy annually using an external tachometer traceable to NIST or equivalent national metrology institute standards.
