Overview
The CZGY YXJ-2 High-Speed Benchtop Centrifuge is an engineered solution for rapid, precise micro-volume sample separation in research and quality control laboratories. Designed on the basis of validated U.S.-origin reference instrumentation (Eppendorf-style architecture), this centrifuge employs fixed-angle rotor geometry and brushless DC motor technology to deliver consistent rotational dynamics under variable load conditions. It operates on the principle of sedimentation acceleration—applying centrifugal force (RCF) to separate particles based on differences in density, size, and shape within viscous or aqueous media. With a maximum rated speed of 16,000 rpm and a peak relative centrifugal force of 17,000 × g, the YXJ-2 supports protocols requiring high-resolution pelleting of subcellular components—including nucleic acids, organelles, and protein complexes—without requiring refrigerated operation. Its compact footprint and low thermal output make it suitable for benchtop deployment in biosafety cabinets, cold rooms, and ambient-lab environments.
Key Features
- Fixed-angle aluminum rotor with precision-machined cavities for 0.5 mL and 1.5 mL conical microtubes—compatible with standard polypropylene, polyethylene, and polycarbonate tubes (tube mass ~1 g)
- Brushless DC motor ensuring stable speed regulation, extended service life (>10,000 hr MTBF), and minimal electromagnetic interference
- Dual-layer stainless steel safety housing with mechanical lid interlock and real-time imbalance sensing—certified to IEC 61010-1:2010 for laboratory equipment safety
- Intuitive analog/digital hybrid control panel with rotary speed dial, digital timer display (0–60 min), and LED status indicators
- Low-noise operation (<65 dB[A]) and minimal temperature rise (<8 °C after 15-min continuous run at max speed), eliminating need for active cooling in most applications
- Vibration-damping rubber feet with vacuum-assisted positioning system—enables secure placement on uneven surfaces without permanent mounting
Sample Compatibility & Compliance
The YXJ-2 accepts standard microcentrifuge tubes (0.5 mL and 1.5 mL) conforming to ISO 7218:2018 microbiological sampling guidelines and ASTM D4127-21 for tube dimensional consistency. Rotors are manufactured from aerospace-grade anodized aluminum alloy (6061-T6), tested per ISO 15195:2020 for mechanical integrity under 125% of maximum rated speed. The device complies with CE marking requirements (2014/30/EU EMC Directive and 2014/35/EU LVD Directive) and meets essential safety criteria outlined in GB/T 13810–2017 (Chinese national standard for laboratory centrifuges). While not certified for GLP/GMP production environments, its design supports audit-ready documentation for method validation in academic, clinical, and industrial R&D labs.
Software & Data Management
The YXJ-2 operates as a standalone instrument with no embedded firmware or network interface. All operational parameters—including speed, time, and rotor identification—are set manually and retained only during active use. For traceability in regulated workflows, users may integrate external logging via calibrated stopwatch timers and manual entry into electronic lab notebooks (ELNs) compliant with 21 CFR Part 11 when paired with appropriate audit-trail software. No proprietary drivers or cloud connectivity are required; maintenance logs and calibration records follow ISO/IEC 17025:2017 recommendations for non-automated instrumentation.
Applications
- Routine pelleting of DNA, RNA, and plasmid preparations during molecular cloning workflows
- Clarification of bacterial lysates prior to chromatographic purification or SDS-PAGE analysis
- Isolation of extracellular vesicles and exosomes from cell culture supernatants
- Pre-concentration of dilute protein solutions for downstream ELISA or mass spectrometry analysis
- Phase separation in solvent-based extraction protocols (e.g., phenol-chloroform RNA isolation)
- High-throughput sample preparation in agricultural biotechnology labs handling plant genomic extracts
FAQ
Can the YXJ-2 be operated inside a cold room or refrigerator?
Yes—its operating temperature range is –10 °C to +40 °C. However, after use in sub-ambient environments, the unit must be run empty at 3,000 rpm for 5 minutes to evaporate condensation before storage.
What is the recommended maintenance interval?
Visual inspection of rotor threads and housing integrity every 200 runs; full rotor balancing verification annually or after any impact event.
Is rotor autoclaving supported?
No—the anodized aluminum rotor is not autoclavable. Cleaning is performed with 70% ethanol and lint-free wipes; avoid halogenated solvents or abrasive agents.
Does the centrifuge include rotor certification documentation?
Yes—a factory-issued rotor test certificate (including burst speed verification at 20,000 rpm) is supplied with each unit.
Can custom rotors be ordered?
CZGY offers OEM rotor design services for qualified institutional partners under NDA; lead time is typically 8–12 weeks.
