Overview
The Xiangyi WTL-6K Mini Benchtop Centrifuge is a compact, low-speed microcentrifuge engineered for routine sample preparation in molecular biology, clinical diagnostics, and quality control laboratories. It operates on the principle of centrifugal force generation via fixed-angle rotor rotation, delivering reproducible sedimentation and pelleting of biological particles—including cells, nucleic acids, and precipitated reagents—in microvolume formats. Designed specifically for high-frequency handling of PCR tubes, spin columns, and filtration devices, the WTL-6K enables rapid reagent collection from tube walls or caps, efficient phase separation in small-volume extractions, and gentle pelleting of temperature-sensitive samples. Its optimized rotor inertia and brushless motor architecture ensure stable acceleration to operational speed within seconds, minimizing thermal drift and mechanical wear over extended duty cycles.
Key Features
- Compact footprint (160 × 200 × 123 mm) ideal for crowded benchtops, biosafety cabinets, or mobile lab setups.
- Brushless DC motor with zero carbon brushes—ensuring maintenance-free operation, extended service life (>10,000 hr MTBF), and consistent torque delivery across voltage fluctuations (AC 100–242 V).
- Lid-actuated safety interlock: automatic rotor stop upon lid opening; immediate restart upon closure—compliant with IEC 61010-1 mechanical safety requirements.
- Dual-rotor compatibility: standard fixed-angle rotor accepts 6 × 1.5 mL, 6 × 0.5 mL, or 6 × 0.2 mL microtubes; optional 8-position PCR strip rotor supports 0.2 mL 8-tube strips.
- Ultra-low acoustic signature (<45 dB[A]) achieved through patented vibration-damping housing and precision-balanced rotor assembly—suitable for quiet environments including teaching labs and cleanrooms.
- Electronic digital timer (0–99 min, 10-sec increments) with memory retention and audible end-of-run signal.
- Transparent polycarbonate lid with ergonomic latch mechanism—enables real-time visual monitoring without interrupting operation.
Sample Compatibility & Compliance
The WTL-6K accommodates standard microcentrifuge tube formats used in nucleic acid purification, enzyme assays, and microfiltration workflows. It is validated for use with polypropylene and polyethylene microtubes rated for ≤2,000 × g. The device meets essential electrical safety standards per IEC 61010-1 and EMC directive 2014/30/EU. While not certified for GLP/GMP production environments, its repeatable speed control, auto-stop safety logic, and non-volatile timer settings support documented procedures aligned with ISO/IEC 17025 method validation frameworks. No refrigeration or vacuum enclosure is integrated; ambient operation is recommended at 10–35 °C and ≤80% RH.
Software & Data Management
The WTL-6K is a standalone instrument with no embedded software or connectivity interfaces (USB, Bluetooth, or Ethernet). All operational parameters are set manually via front-panel controls. Timer settings and speed selection are retained after power cycling. For laboratories requiring audit trails or electronic records, external documentation (e.g., LIMS-integrated logbooks or handwritten SOP entries) must be maintained per FDA 21 CFR Part 11 guidelines when used in regulated QC/QA applications. Firmware updates are not applicable; hardware calibration is performed at factory level using traceable tachometer standards.
Applications
- Rapid pelleting of PCR reaction mixtures prior to thermal cycling.
- Recovery of enzymatic digest products from spin-column membranes.
- Condensation of volatile reagents onto tube caps during cold-room protocols.
- Pre-centrifugation of microfilter devices (e.g., syringe filters, ultrafiltration units) to eliminate air bubbles.
- Gentle sedimentation of bacterial cultures or cell lysates in 0.2–1.5 mL volumes.
- Preparatory steps in ELISA plate washing workflows where microtube-based intermediate storage is required.
FAQ
What is the maximum relative centrifugal force (RCF) achievable with the WTL-6K?
The unit delivers up to 2,000 × g at 6,000 rpm with the standard 1.5 mL rotor configuration.
Can the WTL-6K accommodate 8-tube PCR strips?
Yes—when equipped with the optional 8-position PCR strip rotor, it supports standard 0.2 mL 8-tube configurations.
Is the centrifuge suitable for continuous operation?
It is rated for intermittent use (≤30 min ON / 10 min OFF duty cycle); prolonged continuous runs may accelerate thermal loading in non-ventilated enclosures.
Does the WTL-6K require calibration verification?
While no user-accessible calibration interface exists, annual verification using an NIST-traceable handheld tachometer is recommended for ISO/IEC 17025 compliance.
What safety certifications does this model hold?
It conforms to IEC 61010-1 (electrical safety) and 2014/30/EU (EMC), with mechanical interlocks tested per EN 61000-6-2.
