Overview
The HsiangTai CN-2200 is a compact, microprocessor-controlled benchtop centrifuge engineered for routine sample separation in clinical, academic, and quality control laboratories. It operates on the principle of sedimentation under controlled centrifugal force—generating radial acceleration to separate particles based on density, size, and shape within suspension media. Designed for high reproducibility and operational safety, the CN-2200 delivers stable rotational performance across its 1,000–8,000 rpm speed range (RCF up to 6,660 × g), making it suitable for pelleting cells, precipitating nucleic acids, clarifying lysates, and concentrating particulates in volumes up to 50 mL per tube. Its brushless DC motor ensures low vibration, extended service life, and minimal maintenance—critical for unattended operation during time-sensitive protocols.
Key Features
- Digitally displayed real-time RPM and countdown timer (0–30 min) with ±10 rpm speed accuracy
- ABS polymer housing with integrated transparent viewing window for continuous process monitoring
- Automatic acceleration and deceleration profiles to minimize sample disturbance and rotor stress
- Intelligent imbalance detection system that halts rotation immediately upon detecting ≥5 g mass asymmetry
- Motorized lid interlock with mechanical and electronic dual-safety engagement
- Fail-safe shutdown triggered by sudden power interruption, lid opening mid-run, or thermal overload
- Self-balancing rotor recognition logic—no manual calibration required for compatible angle rotors
- Low-noise operation (<65 dB(A) at 8,000 rpm) optimized for shared lab environments
Sample Compatibility & Compliance
The CN-2200 supports standard conical-bottom polypropylene and polycarbonate tubes (15 mL × 8, 15 mL × 12, 50 mL × 4, and 50 mL × 6 configurations) via interchangeable angle rotors (RA-1508-1, RA-1512S-1, RA-5004, RA-5006). All rotors are certified to ISO 15197:2013 and ASTM F2119-18 for mechanical integrity under cyclic loading. The instrument complies with IEC 61010-1:2010 for laboratory electrical safety and meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU). While not validated for GMP production environments, its audit-ready operational logs and deterministic run parameters support GLP-aligned documentation workflows.
Software & Data Management
The CN-2200 operates as a standalone unit without external software dependency; however, all run parameters—including set speed, actual RCF, elapsed time, and fault codes—are stored in non-volatile memory for retrieval via front-panel navigation. Each session generates a timestamped event log (date/time, rotor ID, speed, duration, termination status) accessible for internal QA review. Though lacking USB or Ethernet connectivity, the device supports manual record-keeping aligned with FDA 21 CFR Part 11 principles when integrated into lab-wide electronic notebook systems (e.g., LabArchives or Benchling) using standardized SOP templates.
Applications
- Cell culture harvest: Pelleting mammalian or bacterial cells from suspension at 3,000–6,000 rpm
- Molecular biology workflows: Precipitation of plasmid DNA, RNA, or PCR products using ethanol/isopropanol washes
- Clinical diagnostics: Serum/plasma separation from whole blood in EDTA or heparin tubes
- Environmental testing: Concentration of suspended solids or microorganisms from water samples
- Pharmaceutical QC: Clarification of filtration supernatants prior to HPLC analysis
- Food & beverage labs: Fat separation in milk homogenates or starch granule isolation
FAQ
What rotor configurations are validated for use with the CN-2200?
The CN-2200 is factory-validated for four angle rotors: RA-1508-1 (15 mL × 8, 8,000 rpm), RA-1512S-1 (15 mL × 12, 7,000 rpm), RA-5004 (50 mL × 4, 7,500 rpm), and RA-5006 (50 mL × 6, 7,000 rpm). Use of non-HsiangTai rotors voids warranty and compromises safety certification.
Does the CN-2200 meet ISO 13485 requirements for medical device manufacturing?
No—the CN-2200 is classified as general-purpose laboratory equipment and is not designed, tested, or documented to fulfill ISO 13485 clause 7.5.2.1 (production equipment qualification). It may be used in pre-production R&D or analytical support roles under risk-assessed SOPs.
Can the timer be bypassed for continuous operation?
No—the timer is hardwired as a safety-critical control function. Continuous operation is intentionally disabled to prevent thermal runaway and rotor fatigue. Maximum runtime per cycle is fixed at 30 minutes.
Is rotor balancing required before each run?
No—the CN-2200 features automatic dynamic balance compensation across all supported rotor types. However, users must ensure symmetrical tube placement (e.g., even-numbered loads with matched mass within ±0.1 g) to maintain mechanical stability.
What maintenance schedule is recommended?
Inspect rotor threads and bucket clips monthly; clean chamber with 70% ethanol biweekly; verify lid seal integrity quarterly; and perform full calibration (speed/RCF verification using traceable tachometer) annually per ISO/IEC 17025 guidelines.
