Overview
The CZGY YXJ-1 is a compact, microprocessor-controlled benchtop electric centrifuge engineered for routine separation tasks in clinical diagnostics, biomedical research, and quality control laboratories. It operates on the principle of sedimentation under centrifugal force—accelerating particle settling based on density, size, and shape differences in suspension. With a maximum rotational speed of 4000 rpm and a peak relative centrifugal force (RCF) of 1960 × g, the YXJ-1 delivers reliable phase separation for low-viscosity biological fluids including whole blood, serum, plasma, urine supernatants, and vaccine suspensions. Its fixed-angle rotor configuration accommodates six 20 mL conical or round-bottom tubes, enabling high-throughput processing without requiring rotor exchange. Designed for ISO 13485-aligned manufacturing environments, the unit complies with IEC 61010-1 safety standards for laboratory electrical equipment, including protection against electric shock, mechanical hazards, and thermal overloads.
Key Features
- Benchtop footprint (235 × 280 × 240 mm) optimized for space-constrained lab benches and biosafety cabinets
- Stepless speed control from 0 to 4000 rpm with real-time LED display of actual rotational speed
- Mechanical timer with 1-minute resolution, adjustable from 0 to 60 minutes; auto-stop function with audible alert
- Integrated polycarbonate safety lid with dual-position mechanical interlock—motor disables if lid is open or improperly seated
- Brushed DC motor with thermal overload protection and low-noise commutation (<65 dB at 4000 rpm)
- Grounded chassis and three-prong power cord meeting IEC 60320 C13 specifications
- Fixed-angle aluminum rotor (6 × 20 mL), anodized for corrosion resistance and easy decontamination
- No vacuum or refrigeration system—suitable for ambient-temperature protocols only
Sample Compatibility & Compliance
The YXJ-1 is validated for use with standard polypropylene, polycarbonate, and glass centrifuge tubes rated for ≥2000 × g. It supports common clinical sample types including EDTA-anticoagulated whole blood (for serum/plasma separation), clarified urine filtrates, bacterial lysates, and adjuvant-stabilized vaccine formulations. Tube loading requires mass balance across opposing positions with ≤3 g deviation per pair to prevent vibration-induced bearing wear. The device meets electromagnetic compatibility (EMC) requirements per EN 61326-1 and carries CE marking for conformity with EU Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). While not certified for GLP or GMP production environments, its operational repeatability (±2% speed accuracy, ±1 min timer tolerance) supports QC documentation under ISO/IEC 17025-accredited testing workflows.
Software & Data Management
The YXJ-1 operates as a standalone analog-digital hybrid instrument with no embedded firmware, network interface, or data export capability. All parameters—including set speed, elapsed time, and run status—are indicated via front-panel LEDs. No software installation, driver dependencies, or computer connectivity are required. For regulated environments requiring audit trails (e.g., FDA 21 CFR Part 11), manual logbook entries—including operator ID, sample ID, speed/time settings, and observed outcomes—are recommended. Calibration verification can be performed using a handheld tachometer traceable to NIST standards; annual verification is advised per ISO/IEC 17025 Clause 6.4.
Applications
- Routine serum/plasma separation from venous blood specimens in hospital core labs and point-of-care clinics
- Preparative isolation of cellular debris following tissue homogenization in molecular biology workflows
- Clarification of bacterial culture supernatants prior to ELISA or HPLC analysis
- Concentration of viral particles or exosomes in diagnostic assay development
- Removal of precipitates from vaccine formulations during stability testing (e.g., USP <1043>)
- Urine sediment pelleting for microscopic urinalysis per CLSI GP16-A3 guidelines
FAQ
What is the maximum relative centrifugal force (RCF) achievable with the YXJ-1?
The YXJ-1 generates a peak RCF of 1960 × g at 4000 rpm with the supplied 6 × 20 mL rotor.
Can this centrifuge be used for temperature-sensitive samples?
No. The YXJ-1 is a non-refrigerated unit and must be operated in climate-controlled environments (15–30°C) to avoid thermal degradation of heat-labile analytes.
Is rotor balancing mandatory before each run?
Yes. Load imbalances exceeding 3 g between opposing tubes may cause excessive vibration, premature bearing failure, and automatic shutdown.
Does the unit support rotor autoclaving?
The aluminum rotor is compatible with dry-heat sterilization (160°C for 2 hours) but not steam autoclaving; repeated exposure to saturated steam may compromise anodized surface integrity.
What maintenance is required for long-term reliability?
Biannual inspection of brush wear, lubrication of drive shaft bearings, and verification of lid interlock functionality are recommended. No user-serviceable electronics are present.
