Overview
The HsiangTai CB-2200 and CB-2060 are compact, microprocessor-controlled benchtop centrifuges engineered for routine low-speed separation tasks in academic, clinical, and quality control laboratories. Designed around a brushless DC motor architecture, these instruments eliminate carbon dust generation and electromagnetic interference—critical for stable operation in shared instrumentation environments. Operating within a speed range of 1,000–8,000 rpm and delivering up to 6,660 × g, they are optimized for sedimentation of cells, precipitates, and particulates from suspensions where high g-force is unnecessary but reproducibility and operational safety are paramount. Their digital interface provides real-time monitoring of rotational speed and countdown timer (00:01–99:59), supporting precise protocol adherence in GLP-compliant workflows.
Key Features
- Brushless DC motor ensures maintenance-free operation, extended service life, and consistent torque delivery across the full speed range.
- Digital LED display shows actual RPM and remaining time simultaneously—no analog dials or mechanical timers subject to drift.
- Programmable acceleration and deceleration profiles minimize sample disturbance during spin-up and braking phases, preserving pellet integrity.
- Integrated safety system includes automatic rotor imbalance detection, lid interlock (centrifugation halts immediately upon lid opening), and instantaneous power-loss response with safe rotor coast-down.
- ABS polymer housing with transparent polycarbonate viewing window enables visual confirmation of rotor status without interrupting operation.
- Auto-balance compensation accommodates minor tube weight discrepancies (±0.5 g per position), reducing risk of vibration-induced error or mechanical stress.
Sample Compatibility & Compliance
The CB-2200 supports multiple fixed-angle rotor configurations—including RA-1508 (15 mL × 8), RA-1512S (15 mL × 12), RA-5004 (50 mL × 4), and RA-5006 (50 mL × 6)—enabling flexible throughput for common laboratory tubes (1.5–50 mL). All rotors are precision-balanced and certified for use at rated speeds per ISO 15197 and IEC 61010-2-020 safety standards. The unit complies with CE marking requirements for electrical safety and electromagnetic compatibility (EMC Directive 2014/30/EU). While not designed for biosafety containment, its sealed motor compartment and non-porous housing meet general hygiene guidelines for Class II lab environments under CLSI GP26-A4 recommendations.
Software & Data Management
These models operate via embedded firmware with no external PC dependency; however, all run parameters (set speed, time, rotor ID if encoded, start/stop timestamps) are logged internally with non-volatile memory retention. Audit trail functionality supports basic traceability for routine QC documentation—sufficient for ISO/IEC 17025 Clause 7.7 record-keeping when paired with manual logbook entry. For regulated environments requiring electronic signatures or 21 CFR Part 11 compliance, integration with third-party LIMS or ELN systems is achievable via RS-232 serial output (optional adapter), enabling automated parameter export and session archiving.
Applications
- Pre-analytical processing of whole blood, serum, and plasma in clinical labs (e.g., hematocrit preparation, antibody isolation).
- Sedimentation of bacterial pellets post-culture for downstream DNA extraction or protein harvesting.
- Clarification of cell lysates prior to chromatography or electrophoresis.
- Separation of organic/aqueous phases in solvent-based extractions (e.g., phenol-chloroform protocols).
- Routine cleaning of nanoparticle suspensions or colloidal dispersions before DLS or TEM analysis.
- Quality assurance testing of reagent stability and suspension homogeneity in pharmaceutical manufacturing support labs.
FAQ
What rotor types are compatible with the CB-2200?
The CB-2200 accepts only HsiangTai-certified fixed-angle rotors: RA-1508, RA-1512S, RA-5004, and RA-5006. Swapping rotors requires manual installation and verification of maximum speed limits per rotor specification.
Is the CB-2200 suitable for centrifuging infectious samples?
No. It lacks sealed biocontainment features (e.g., aerosol-tight rotor lids or vacuum-sealed chambers) and is intended for non-hazardous or BSL-1 applications only.
Does the centrifuge retain settings after power cycling?
Yes—the last-used speed and time values are preserved in memory, though default startup remains at 1,000 rpm and 1 minute unless reprogrammed.
Can it be used with conical-bottom microcentrifuge tubes?
Only when mounted in appropriate adapters within compatible rotors (e.g., RA-1508 with 15 mL conical tube inserts); direct insertion of non-standard tubes may compromise balance and safety.
What maintenance is required for long-term reliability?
Routine cleaning of the chamber and rotor seating surfaces with 70% ethanol; annual inspection of rotor threads and bearing play by qualified service personnel is recommended per manufacturer’s maintenance schedule.
