Overview
The HsiangTai CB-2160 is a purpose-engineered benchtop centrifuge optimized for routine plasma processing and hematology workflows in clinical laboratories, blood banks, and research settings. Designed around the principles of low-speed sedimentation centrifugation—operating within the 500–4000 rpm range and delivering up to 1610 × g—it meets the precise mechanical requirements for gentle yet effective separation of whole blood components without compromising cell integrity. Its fixed-angle SERO rotor configuration (6 × 12-position, accommodating twelve 75 mm glass test tubes per run) ensures consistent orientation and reproducible pelleting of erythrocytes, leukocytes, and platelets—critical for downstream applications such as serum extraction, lymphocyte isolation, and Coombs testing. The unit complies with IEC 61010-1 safety standards for laboratory electrical equipment and incorporates mechanical and electronic safeguards aligned with GLP-aligned operational protocols.
Key Features
- Brushless DC motor ensuring extended service life, minimal heat generation, and high rotational stability across all speed ranges
- Digital LED display for real-time monitoring of set and actual speed (rpm) and remaining timer duration (1–100 min)
- Programmable multi-step operation: three preset protocols (e.g., 2200 rpm/490 × g; 3000 rpm/910 × g; 3000 rpm/910 × g with 1 min duration) support standardized hematological workflows
- Automatic acceleration and deceleration profiles minimize sample disturbance and reduce mechanical stress on rotor assemblies
- Integrated auto-balance detection system halts operation if mass asymmetry exceeds ±5 g per tube pair, preventing vibration-induced damage
- Lid interlock mechanism disables rotation when the chamber is open, satisfying ISO 13485 prerequisite controls for medical device environments
- ABS polymer housing with integrated transparent polycarbonate viewing window enables visual confirmation of rotor status without interrupting operation
Sample Compatibility & Compliance
The CB-2160 accommodates standard 75 mm glass test tubes—commonly used for blood collection and manual serology assays—including those conforming to CLSI H20-A3 specifications for tube geometry and wall thickness. Its rotor design supports uniform radial distribution of samples, minimizing shear-induced hemolysis during spin-down. While not certified for biosafety level (BSL) containment, the unit is routinely deployed in ISO 15189-accredited clinical labs for pre-analytical sample preparation. It satisfies essential performance criteria referenced in CLSI EP05-A3 (evaluation of centrifuge precision) and aligns with analytical preconditions outlined in USP for dissolution sample handling where centrifugal clarification is required.
Software & Data Management
The CB-2160 operates as a standalone instrument without embedded software or network connectivity. All operational parameters are configured via front-panel controls, and no data logging, audit trail, or electronic record functionality is provided. As such, it is suitable for environments operating under non-21 CFR Part 11-compliant workflows or where paper-based procedural documentation fulfills local quality system requirements (e.g., ISO 9001 or CAP checklist GEN.40340). Users are advised to maintain manual logs of run parameters, maintenance intervals, and calibration verification dates to support traceability in regulated settings.
Applications
- Serum/plasma separation from anticoagulated or clotted whole blood specimens
- Red blood cell washing prior to direct/indirect antiglobulin testing (DAT/IAT)
- Lymphocyte and mononuclear cell isolation using density gradient media (e.g., Ficoll-Paque™)
- Crossmatching and antibody screening procedures requiring controlled pelleting
- Coagulation assay preparation, including prothrombin time (PT) and activated partial thromboplastin time (aPTT) sample clarification
- Pre-analytical processing for flow cytometry, ELISA, and molecular diagnostics where intact cellular morphology must be preserved
FAQ
What tube sizes does the CB-2160 accept?
It is configured exclusively for 75 mm glass test tubes arranged in a 12-position layout per rotor bucket (total capacity: 12 × 75 mm tubes). Plastic microtubes or conical centrifuge tubes are not supported.
Is the CB-2160 compliant with FDA 21 CFR Part 11?
No. The device lacks electronic records, user authentication, or audit trail capabilities and is intended for use in non-electronic-data-integrity-regulated environments.
Can the rotor be autoclaved?
The SERO fixed-angle rotor is constructed from anodized aluminum alloy and is not autoclavable. Cleaning is performed using 70% ethanol or isopropyl alcohol wipes; immersion or ultrasonic cleaning is not recommended.
Does the unit include calibration documentation?
Factory calibration certificates are available upon request at time of purchase; annual verification using NIST-traceable tachometers is recommended per CLSI GP26-A4 guidelines.
What maintenance is required?
Routine inspection of rotor threads, lid seal integrity, and motor ventilation grilles every 6 months; brushless motor requires no periodic servicing but benefits from dust-free placement and stable ambient temperatures (15–30 °C).
