Overview
The CZGY 80-2 Benchtop Electric Centrifuge is a compact, high-reliability centrifugation system engineered for routine separation tasks in clinical diagnostics, biochemical research, and quality control laboratories. Utilizing fixed-angle rotor geometry and brush-type induction motor drive, it delivers consistent rotational acceleration up to 4000 rpm with a maximum relative centrifugal force (RCF) of 1960 × g—sufficient for sedimentation of erythrocytes, serum separation, precipitate recovery from dilute biological suspensions, and pre-filtration concentration of vaccine intermediates. Its rigid cast-aluminum housing, balanced rotor assembly, and integrated safety interlock ensure stable operation under repeated daily use. Designed for ambient laboratory environments (10–35 °C, ≤80% RH), the unit complies with IEC 61010-1 safety standards for electrical equipment used in measurement, control, and laboratory applications.
Key Features
- Benchtop footprint (290 × 330 × 260 mm) optimized for space-constrained labs and mobile diagnostic units
- Adjustable analog speed control (0–4000 rpm) with real-time visual feedback via calibrated dial
- Mechanical timer (0–60 minutes) with automatic shut-off and audible end-of-cycle signal
- 12-position fixed-angle rotor accommodating standard 20 mL glass or polypropylene centrifuge tubes (max 12 × 20 mL)
- 80 W high-torque motor delivering rapid acceleration (<30 s to reach 4000 rpm) and smooth deceleration without coasting
- Transparent polycarbonate lid with dual mechanical safety latch and automatic power cutoff when opened mid-cycle
- Grounded chassis design meeting Class I protection requirements per IEC 61010-1
- No external cooling required; passive thermal management ensures continuous operation at rated load
Sample Compatibility & Compliance
The 80-2 supports standard conical-bottom 20 mL centrifuge tubes (diameter ≤16 mm, height ≤120 mm), including borosilicate glass, polypropylene, and PETG variants. Tube loading requires mass balance across opposing positions (±3 g tolerance) to maintain rotor integrity and minimize vibration. While not validated for biosafety level 3 (BSL-3) containment or aerosol-generating protocols, the unit is routinely deployed in CLIA-waived point-of-care testing, veterinary diagnostics, and academic teaching labs. It meets general-purpose electrical safety requirements (IEC 61010-1, EN 61326-1) and carries CE marking for the European Economic Area. Note: This model is not FDA 510(k)-cleared, nor does it support 21 CFR Part 11-compliant audit trails or electronic records.
Software & Data Management
The CZGY 80-2 operates as a standalone electromechanical instrument with no embedded microprocessor, firmware, or digital interface. All operational parameters—including speed setpoint, timer duration, and motor status—are controlled manually via front-panel dials and switches. No software installation, driver dependencies, or data export capabilities are provided. This architecture eliminates cybersecurity vulnerabilities, reduces maintenance complexity, and ensures long-term functional consistency—ideal for regulated environments where validation stability and traceability of manual operator actions are prioritized over automation features.
Applications
- Routine serum/plasma separation from whole blood specimens in hospital clinical labs
- Urea clearance assay preparation and supernatant isolation in renal function studies
- Precipitation harvesting in small-scale vaccine adjuvant formulation (e.g., aluminum hydroxide suspensions)
- Cell pellet collection during microbial culture processing and enzymatic extraction workflows
- Clarification of tissue homogenates prior to electrophoresis or ELISA analysis
- Quality assurance testing of reagent stability and particulate contamination in diagnostic kits
FAQ
Is the 80-2 suitable for centrifuging infectious samples?
No. It lacks sealed rotor containment, biocontainment certification (e.g., ISO 13485), or HEPA filtration and must only be used with non-aerosolizing, low-risk biological materials.
Can I use microcentrifuge tubes (1.5–2.0 mL) in this rotor?
No. The rotor accepts only tubes with outer diameter ≤16 mm and length ≤120 mm; standard microtubes require adapter sleeves not supplied with this model.
Does the unit include a rotor balancing tool or calibration certificate?
No. Balancing is performed manually using an analytical balance (±0.1 g resolution recommended); factory calibration documentation is not provided.
What is the expected service life under daily usage?
With proper tube balancing and adherence to the 60-minute maximum continuous runtime per cycle, the motor and bearing assembly are rated for ≥10,000 operational hours.
Is replacement rotor available separately?
Yes. The original 12-place fixed-angle rotor (CZGY part #R80-2-F12) is available through authorized distributors with lead time of 2–4 weeks.
