Overview
The HUXI HL-8KS is a compact, benchtop microcentrifuge engineered for precision and reliability in routine biomolecular separation tasks. Designed around a brushless DC motor architecture, it delivers stable rotational dynamics at up to 8,000 rpm, generating a maximum relative centrifugal force (RCF) of 3,700 × g—sufficient for pelleting nucleic acids, cellular organelles, and small-volume protein precipitates. Its operation adheres to fundamental principles of sedimentation-based separation under radial acceleration, where particle migration velocity is governed by density differential, rotor radius, and angular velocity squared. The device complies with IEC 61010-1:2010 safety standards for laboratory electrical equipment and incorporates dual mechanical braking and lid-interlock systems to ensure operator safety during rapid deceleration cycles.
Key Features
- Brushless DC motor delivering high torque-to-volume ratio, low thermal drift, and extended service life (>10,000 hours MTBF)
- Semi-automatic lid actuation with integrated electromagnetic brake: full stop within 3 seconds upon lid opening, minimizing sample disturbance and enhancing reproducibility
- Autoclavable aluminum fixed-angle rotors—compatible with standard 1.5 mL and 2.0 mL microtubes as well as 8 × 4 × 0.2 mL PCR strip configurations
- Wide-input switching power supply (AC 100–240 V, 50/60 Hz), enabling stable operation across global laboratory voltage infrastructures without external transformers
- Acoustically optimized housing with vibration-damping feet and balanced rotor assembly, achieving ≤45 dB(A) noise emission during operation
- Intuitive digital interface with LED display, offering real-time monitoring of speed, time remaining, and error codes (e.g., imbalance detection, overtemperature warning)
Sample Compatibility & Compliance
The HL-8KS supports common low-volume consumables used in molecular biology workflows, including polypropylene microcentrifuge tubes (1.5 mL and 2.0 mL), PCR strips, and capillary tubes. Rotors are certified for autoclaving at 121 °C for 20 minutes (ISO 17664-compliant cleaning validation), supporting GLP/GMP-aligned lab practices requiring traceable decontamination. While not FDA 21 CFR Part 11–validated out-of-the-box, the instrument’s timer-based operation, non-volatile parameter retention, and absence of network connectivity render it suitable for regulated environments where audit trails are maintained manually or via LIMS integration. It meets EN 61326-1:2013 requirements for electromagnetic compatibility in laboratory settings.
Software & Data Management
The HL-8KS operates as a standalone instrument with no embedded firmware-based data logging or USB/Bluetooth connectivity. All operational parameters—including speed, run time, and rotor type—are set via front-panel controls and retained in non-volatile memory across power cycles. For laboratories requiring electronic recordkeeping, integration is achieved through external time-stamped logbooks or LIMS interfaces that capture user-entered run metadata. The absence of proprietary software reduces cybersecurity exposure and simplifies qualification protocols under ISO/IEC 17025 or ISO 9001 frameworks.
Applications
- Routine pelleting of DNA/RNA from spin-column eluates or phenol-chloroform extractions
- Clarification of bacterial lysates prior to SDS-PAGE or Western blotting
- Separation of PCR reaction mixtures and cleanup of enzymatic digests
- Micro-volume solvent extraction in analytical chemistry workflows (e.g., pesticide residue analysis in food testing)
- Preparative centrifugation of enzyme assays, immunoassays, and ELISA plate supernatants
- Quality control steps in pharmaceutical excipient processing and lyophilized formulation development
FAQ
Is the HL-8KS suitable for clinical diagnostics applications?
Yes—its RCF capability, rotor sterilizability, and compliance with IEC 61010-1 make it appropriate for CLIA-waived or moderate-complexity testing environments where centrifugation is part of specimen preparation.
Can the rotor be cleaned with ethanol or isopropanol?
Yes—aluminum rotors tolerate repeated wiping with 70% ethanol or isopropanol; however, prolonged exposure to strong oxidizers (e.g., sodium hypochlorite) is not recommended.
Does the instrument include imbalance detection?
Yes—the control system continuously monitors motor current draw and triggers automatic shutdown if rotor load asymmetry exceeds ±5% mass differential.
What is the warranty coverage?
HUXI provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship under normal laboratory use.
Is rotor calibration required before first use?
No—factory-calibrated rotors require no user recalibration; however, users should verify balance and secure fit prior to each run per ISO 20957-2:2013 guidelines.
