Overview
The LuXiangYi TG12X Capillary Blood Centrifuge is a precision-engineered benchtop centrifuge specifically designed for hematological applications requiring high reproducibility and strict adherence to clinical laboratory standards. It operates on the principle of sedimentation-based separation under controlled centrifugal force, enabling rapid and quantitative determination of packed cell volume (PCV), also known as hematocrit (Hct), in whole blood samples. Unlike general-purpose centrifuges, the TG12X integrates a dedicated horizontal swing-out rotor optimized for standardized capillary tube geometry (e.g., 75 mm length, 1.0–1.2 mm internal diameter), ensuring uniform radial acceleration across all sample positions and minimizing inter-run variability. Its brushless DC motor delivers stable rotational performance with minimal thermal drift and zero carbon brush wear—critical for long-term calibration integrity in regulated environments such as hospital core labs, blood banks, and CLIA-certified point-of-care testing sites.
Key Features
- Microprocessor-controlled operation with digital RPM/RCF/time display and programmable run profiles (speed, time, acceleration/deceleration ramps)
- Electronic safety door lock with automatic rotor recognition and interlock verification prior to start-up
- Dual-capacity rotor compatibility: supports both 12-tube and 24-tube configurations at identical maximum speed (12,000 rpm) and RCF (13,500 × g)
- Integrated over-speed, imbalance, and lid-open detection systems compliant with IEC 61010-2-20 safety requirements
- Low-noise enclosure (<65 dB[A]) engineered for continuous operation in shared laboratory or clinical examination rooms
- Compact footprint (230 × 310 × 240 mm) and lightweight chassis (12 kg) suitable for mobile carts, biosafety cabinets, or limited-space diagnostic stations
Sample Compatibility & Compliance
The TG12X accepts standard heparinized or EDTA-coated glass or plastic capillary tubes (75 mm length, nominal 1.0–1.2 mm ID), conforming to ISO 8655-5 and CLSI H20-A3 specifications for hematocrit measurement. It meets essential performance criteria outlined in ASTM D7373 (Standard Practice for Determination of Hematocrit by Centrifugation) and supports traceable calibration per ISO/IEC 17025:2017 requirements when paired with NIST-traceable tachometers and certified reference capillaries. While not FDA 510(k)-cleared as an IVD device, its design aligns with Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) documentation expectations for instrument qualification (IQ/OQ/PQ), including audit-ready event logging of run parameters and fault codes.
Software & Data Management
The TG12X operates via embedded firmware without external PC dependency; however, it supports manual data recording through its real-time digital display and non-volatile memory storing the last 10 run logs (including date/time stamp, set speed, actual RCF, duration, and error flags). For laboratories implementing electronic lab notebooks (ELN) or LIS integration, optional RS-232 serial output (with protocol documentation available upon request) enables automated transfer of run metadata. All firmware updates are delivered via secure USB flash drive and require administrator-level authentication—ensuring version control and compliance with FDA 21 CFR Part 11 principles for electronic records where local validation protocols are applied.
Applications
- Quantitative hematocrit (Hct) determination in clinical hematology and emergency triage settings
- Micro-volume plasma or serum separation from fingerstick or heelstick blood samples (e.g., neonatal screening, pediatric diagnostics)
- Preparation of capillary blood smears with consistent cell monolayer formation
- Isolation of platelet-rich plasma (PRP) for point-of-care regenerative medicine workflows
- Quality control of anticoagulant efficacy in capillary collection devices
- Research applications involving small-volume density gradient separations (e.g., PBMC isolation using low-viscosity media)
FAQ
What capillary tube dimensions are supported?
The TG12X is validated for 75 mm length capillaries with internal diameters between 1.0 mm and 1.2 mm. Tubes exceeding ±0.05 mm tolerance may cause imbalance or incomplete sedimentation.
Does the centrifuge support automatic brake release after completion?
Yes—the unit features programmable deceleration profiles and defaults to gentle coast-down to prevent resuspension of sedimented erythrocyte columns.
Is rotor balancing required before each run?
No. The horizontal swing-out rotor is factory-balanced and symmetrically loaded; users must ensure equal tube count per arm (e.g., 12 or 24 total) but no manual counterweighting is needed.
Can the TG12X be used for non-blood viscous fluids?
It is not recommended for high-viscosity or particulate-laden samples outside hematological use cases, as rotor clearance and airflow cooling are optimized for low-density aqueous suspensions.
What maintenance intervals are specified?
Annual verification of rotor integrity, door latch torque, and tachometer accuracy is advised; brushless motor requires no scheduled replacement, and no lubrication points exist in the drive assembly.
