CZGY 800 Export-Grade Benchtop Centrifuge

Overview

The CZGY 800 Export-Grade Benchtop Centrifuge is a compact, energy-efficient, and operator-safe centrifugation system engineered for routine separation tasks in clinical diagnostics, biomedical research, and quality control laboratories. Utilizing fixed-angle rotor architecture and brushless DC motor technology, it delivers stable rotational performance across its full speed range (0–4000 rpm), generating a maximum relative centrifugal force (RCF) of 1960 × g at top speed. Designed for compliance with international export standards—including IEC 61010-1 for electrical safety and ISO 13485-aligned manufacturing practices—the instrument supports reproducible sedimentation of biological suspensions such as whole blood, serum, plasma, urine supernatants, and vaccine intermediates. Its low thermal footprint (40 W nominal power draw) and minimal footprint (235 × 280 × 240 mm) make it suitable for space-constrained lab environments, including mobile clinics, field testing units, and teaching laboratories.

Key Features

• Benchtop form factor with reinforced ABS housing and integrated vibration-damping base for stable operation on standard laboratory countertops
• Stepless analog speed control dial enabling precise adjustment from standstill to 4000 rpm with real-time visual feedback
• Mechanical timer with 0–60 minute range, offering repeatable run duration control without dependency on software or digital interfaces
• Interlocked transparent polycarbonate lid that automatically disables motor operation when unlatched—compliant with EN 61010-2-020 mechanical safety requirements
• Fixed-angle rotor (6-position, 20 mL tube capacity) fabricated from anodized aluminum alloy for corrosion resistance and long-term dimensional stability
• Grounding terminal included as standard; mandatory grounding ensures operator protection against leakage current under fault conditions
• No maintenance-required motor design with sealed bearings and thermal overload protection circuitry

Sample Compatibility & Compliance

The CZGY 800 accommodates standard conical-bottom polypropylene or glass centrifuge tubes (10–20 mL) and is routinely deployed for phase separation in hematology (e.g., serum/plasma isolation post-clotting), urinalysis (sediment concentration), and bioprocess intermediate handling (e.g., cell harvest prior to filtration). Tube loading requires mass balance within ±3 g across opposing positions to prevent rotor wobble and bearing stress—consistent with CLSI GP47-A4 recommendations for manual centrifuge operation. The device meets CE marking requirements for the European Economic Area and carries documentation supporting conformity with IEC 61010-1:2010 (Safety of Electrical Equipment for Measurement, Control, and Laboratory Use). It is not intended for high-speed, ultra-centrifugation, or sealed-bottle applications requiring biocontainment certification (e.g., BSL-2+).

Software & Data Management

As a manually operated, analog-control centrifuge, the CZGY 800 does not incorporate embedded firmware, touchscreen interface, or data logging capabilities. All operational parameters—including speed setting, timer activation, and power state—are controlled via physical dials and switches. This architecture eliminates dependencies on proprietary software, network connectivity, or electronic audit trails, making it inherently compatible with GLP- and GMP-regulated environments where instrument qualification focuses on mechanical calibration and user training records rather than electronic record integrity. Calibration verification may be performed using an external tachometer and timer stopwatch, with documented evidence retained per ISO/IEC 17025 clause 6.4.10.

Applications

• Routine serum and plasma separation from clotted or anticoagulated whole blood specimens in hospital core labs and point-of-care settings
• Concentration of urinary sediments for microscopic examination in clinical pathology workflows
• Preliminary clarification of bacterial or yeast cultures during vaccine development and quality release testing
• Removal of particulates from buffer solutions and reagent stocks in molecular biology preparation areas
• Teaching laboratory demonstrations of sedimentation kinetics, density-based separation, and rotor dynamics principles

FAQ

What is the maximum relative centrifugal force (RCF) achievable with this centrifuge?
At 4000 rpm with the standard 6 × 20 mL rotor, the maximum RCF is 1960 × g, calculated at the tube bottom position using the rotor radius of 105 mm.
Is this centrifuge suitable for use with infectious samples?
It is not certified for biosafety containment (e.g., no aerosol-tight sealing or HEPA filtration); users must implement secondary containment (e.g., sealed buckets or OSHA-compliant biocontainment tubes) when processing potentially hazardous materials.
Does the unit include a rotor imbalance detection system?
No—imbalance detection is manual and relies on operator adherence to the ±3 g loading tolerance specified in the user manual; audible vibration or excessive movement indicates improper load distribution.
Can the timer be bypassed for continuous operation?
No—the mechanical timer is non-defeatable; the motor stops automatically upon timer expiration, and restart requires manual reset and power cycling.
What regulatory documentation is provided for export destinations?
CE Declaration of Conformity, RoHS compliance statement, factory test report (including speed accuracy and timer deviation verification), and English-language user manual compliant with IEC 62366-1 usability engineering requirements are supplied with each unit.
