Overview
The Xiangyi WTL-Series Palm-Sized Centrifuge is a compact, high-efficiency benchtop centrifuge engineered for rapid micro-volume sample separation in resource-constrained or space-limited laboratory environments. Designed around brushless DC motor technology, it delivers stable rotational performance without carbon brushes—eliminating wear-related maintenance and ensuring long-term torque consistency across repeated start-stop cycles. Its operational principle relies on radial acceleration generated by controlled angular velocity, enabling sedimentation of suspended particles based on density differentials in small-volume tubes (0.2–1.5 mL). The device operates within three fixed-speed configurations (4,000 rpm, 6,000 rpm, and 10,000 rpm), each calibrated to deliver precise relative centrifugal force (RCF) values—900 × g, 2,000 × g, and 5,000 × g respectively—making it suitable for routine pelleting of cellular debris, precipitated nucleic acids, or protein aggregates in molecular biology, clinical diagnostics, and quality control workflows.
Key Features
- Brushless DC motor architecture ensures zero brush dust generation, thermal stability under continuous operation, and >10,000-hour service life with no scheduled maintenance.
- Patented acoustic damping housing reduces operational noise to <53 dB(A), meeting ISO 7779-compliant sound emission limits for shared lab spaces.
- Integrated rotor lock mechanism prevents accidental lid opening during rotation, satisfying IEC 61010-2-020 mechanical safety requirements for centrifugal equipment.
- Fixed-speed selection via tactile push-button interface eliminates parameter drift and simplifies SOP-driven operation in GLP-compliant settings.
- Compact footprint (160 × 200 × 123 mm) and low mass (1.2 kg) enable deployment on biosafety cabinets, laminar flow hoods, or mobile lab carts without structural reinforcement.
- Universal voltage input (AC 100–242 V, 50/60 Hz) supports global deployment without external transformers or frequency converters.
Sample Compatibility & Compliance
The WTL-Series accommodates standard microcentrifuge tubes (0.2 mL, 0.5 mL, and 1.5 mL) as well as 8-well PCR strip formats, supporting both single-tube and multi-strip configurations. Rotors are precision-balanced and certified for use with polypropylene and polyethylene tubes rated for ≥5,000 × g. All models comply with the essential safety and electromagnetic compatibility (EMC) clauses of IEC 61010-1:2010 and IEC 61326-1:2012. While not individually FDA 510(k)-cleared, the design adheres to general controls applicable to Class I laboratory equipment under 21 CFR Part 866.2100. Documentation includes Declaration of Conformity (DoC) and technical files available upon request for internal audit or procurement validation.
Software & Data Management
As a manually operated fixed-speed instrument, the WTL-Series does not incorporate embedded software, touchscreen interfaces, or digital data logging. This architecture aligns with ISO/IEC 17025:2017 Clause 6.4.10 requirements for equipment where manual operation and visual verification are integral to method validation. Users record run parameters (speed, duration, tube type) directly in lab notebooks or LIMS-compatible electronic records. No firmware updates, cybersecurity patches, or 21 CFR Part 11 audit trails are required—reducing IT validation burden in regulated QC/QA laboratories.
Applications
- Routine spin-down of enzymatic reaction mixtures prior to electrophoresis or HPLC injection.
- Clarification of bacterial lysates in plasmid miniprep protocols (e.g., alkaline lysis).
- Microfiltration support for solvent extraction workflows in environmental testing labs.
- Point-of-care sample preparation in field-deployable diagnostic kits requiring portable centrifugation.
- Teaching laboratories where mechanical simplicity, safety, and reproducibility are pedagogical priorities.
FAQ
What is the maximum relative centrifugal force (RCF) achievable with the WTL-10K model?
The WTL-10K delivers a verified RCF of 5,000 × g at 10,000 rpm when using 1.5 mL tubes in the standard angle rotor.
Can this centrifuge accommodate 0.2 mL PCR strips across all speed variants?
Yes—each model supports dual 8-well PCR strip loading (2 × 8 × 0.2 mL), with rotor geometry optimized to prevent strip deformation at rated speeds.
Is the motor rated for continuous operation?
The brushless DC motor is thermally rated for uninterrupted operation up to 30 minutes per cycle, with automatic thermal cutoff protection activated above 65°C winding temperature.
Does the unit include a rotor locking mechanism?
Yes—a spring-loaded mechanical latch engages automatically upon lid closure and disengages only after full deceleration, preventing forced opening during rotation.
Are spare rotors or adapters available for purchase separately?
Xiangyi offers OEM-certified replacement rotors (P/N: WTL-R01 for 1.5/0.5/0.2 mL tubes; P/N: WTL-R02 for PCR strips), supplied with individual balance certification reports.
