Overview
The Xiangyi TD-24K Blood Typing Microcolumn Gel Centrifuge is a purpose-built benchtop centrifuge engineered specifically for standardized serological testing in clinical transfusion laboratories and blood bank settings. It operates on the principle of horizontal swing-out centrifugation, applying controlled relative centrifugal force (RCF) to separate red blood cells from serum or plasma within pre-filled microcolumn gel cards—enabling reliable detection of antigen–antibody reactions in ABO/Rh typing, antibody screening, identification, and direct antiglobulin tests (DAT). Unlike general-purpose centrifuges, the TD-24K integrates fixed-speed protocols calibrated to international microcolumn gel assay requirements (e.g., Ortho BioVue®, DiaMed ID-System®, and Grifols Gel Test®), ensuring reproducible sedimentation kinetics across batched card processing. Its low-speed operation (up to 2000 rpm, max 1790 × g) avoids hemolysis while maintaining sufficient force to resolve weak agglutinates in gel matrices—critical for high-sensitivity immunohematology diagnostics.
Key Features
- Optimized rotor geometry accommodating exactly 24 microcolumn gel cards per run—maximizing throughput without compromising balance or thermal stability.
- Brushless DC motor delivering consistent torque, extended service life (>20,000 hr MTBF), and zero carbon dust emission—essential for cleanroom-adjacent clinical environments.
- Digital microprocessor controller with pre-programmed, lockable protocols aligned with manufacturer-recommended centrifugation parameters for leading gel card systems (e.g., 10 min @ 1000 rpm for initial incubation spin; 5 min @ 2000 rpm for final reading spin).
- Real-time RPM/RCF display with automatic rotor recognition logic—prevents misconfiguration when switching between compatible accessories.
- Acoustically damped housing and vibration-dampening feet reduce operational noise to ≤55 dB(A), meeting WHO and ISO 15189 ambient noise guidelines for diagnostic laboratories.
- One-piece injection-molded chassis ensures structural rigidity, corrosion resistance, and ease of surface decontamination using 70% ethanol or hospital-grade disinfectants.
Sample Compatibility & Compliance
The TD-24K is validated for use with all commercially available 8-column and 12-column microcolumn gel cards (including ID-Card®, Gamma-Card®, and Immucor Capture-R® formats). It supports both manual and semi-automated workflow integration—compatible with LIS interfaces via optional RS-232 output. The device conforms to IEC 61010-1:2010 safety standards for laboratory electrical equipment and meets electromagnetic compatibility (EMC) requirements per EN 61326-1. While not FDA 510(k)-cleared as an IVD device itself, its operational parameters align with CLSI EP15-A3 and ISO 15189:2022 requirements for verification of centrifugation steps in accredited blood bank testing procedures.
Software & Data Management
The TD-24K features embedded firmware supporting audit-trail-capable operation logs—including date/time stamps, selected program ID, actual run duration, final speed, and error codes. Optional USB data export enables traceable record retention for GLP/GMP and CAP inspection readiness. No proprietary software installation is required; configuration and protocol editing are performed directly via front-panel keypad and LCD interface. All user-defined programs can be password-protected to maintain method integrity in multi-operator environments.
Applications
- ABO and Rh(D) blood group determination using gel card agglutination assays.
- Antibody screening and identification in pre-transfusion testing.
- Direct antiglobulin test (DAT) for detecting in vivo sensitization.
- Red blood cell washing prior to indirect antiglobulin testing (IAT).
- Quality control validation of gel card lot performance under standardized centrifugation conditions.
- Training and competency assessment in immunohematology education programs.
FAQ
Is the TD-24K compliant with ISO 15189 quality management requirements for blood bank laboratories?
Yes—the instrument’s repeatable RCF delivery, programmable protocol locking, and electronic log functionality support documentation of critical process parameters required under ISO 15189:2022 clause 5.5.3.
Can the centrifuge accommodate non-gel card applications, such as standard microtubes or PCR strips?
No—this model is mechanically and functionally dedicated to microcolumn gel card carriers only; it does not accept tube adapters or alternative rotors.
What maintenance intervals are recommended for long-term reliability?
Annual calibration verification of speed and timer accuracy is advised; brushless motor requires no scheduled lubrication or brush replacement.
Does the TD-24K support remote monitoring or network connectivity?
Not natively—but RS-232 output allows integration with third-party lab automation middleware for status polling and event logging.
Is the device suitable for use in CAP-accredited or AABB-accredited facilities?
Yes—its design intent, documented performance consistency, and audit-ready operational logs meet technical verification expectations outlined in CAP GEN.41525 and AABB Standard 5.12.1.
