Xiangyi CTK80R Automated Cap-Removal Refrigerated Centrifuge

Overview

The Xiangyi CTK80R Automated Cap-Removal Refrigerated Centrifuge is a purpose-engineered benchtop system designed for high-throughput clinical laboratories processing vacuum blood collection tubes. It integrates refrigerated centrifugation with fully automated cap removal in a single, validated workflow—eliminating manual decapping, a known source of operator fatigue, sample re-mixing, aerosol generation, and biosafety risk. The instrument operates on the principle of horizontal swing-out rotor centrifugation under controlled temperature (typically 4 °C to 25 °C), enabling efficient separation of whole blood into serum/plasma and cellular fractions while preserving analyte stability. Its mechanical architecture conforms to ISO 13485–aligned manufacturing practices and supports GLP-compliant operation through traceable parameter logging and hardware interlocks.

Key Features

• Integrated cap-removal mechanism with >90% success rate across standard 13 mm diameter vacuum tubes (75 mm and 100 mm lengths), verified per IEC 61010-2-020 mechanical safety requirements
• Refrigerated operation with PID-controlled compressor cooling system maintaining ±1 °C accuracy over full speed range (0–4000 rpm)
• Brushless AC frequency-controlled motor delivering precise speed regulation (±10 rpm at 4000 rpm) and rapid acceleration/deceleration profiles (≤15 s to reach max speed; ≤20 s to stop)
• Automatic RCF (Relative Centrifugal Force) calculation and real-time display, eliminating manual conversion errors
• Dual-stage vibration damping system with dynamic imbalance compensation—enabling automatic rotor balancing even with ±5 g tube mass variation
• Electromechanical door lock compliant with EN 61010-1:2010; centrifuge remains inert unless lid is fully engaged, and halts immediately upon unauthorized opening during run
• 7-inch capacitive touch LCD interface with multilingual support (English, Spanish, Arabic), intuitive icon-driven navigation, and password-protected method storage

Sample Compatibility & Compliance

The CTK80R accepts all globally standardized vacuum blood collection tubes meeting CLSI H20-A3 specifications—including EDTA, heparin, citrate, serum separator (SST), and plasma separator (PST) tubes. Its horizontal rotor accommodates up to 80 tubes simultaneously (13 × 75 mm or 13 × 100 mm configurations), supporting batch processing aligned with CAP-accredited laboratory workflows. The system meets essential safety and electromagnetic compatibility standards: IEC 61010-1 (electrical safety), IEC 61326-1 (EMC), and ISO 15195 (calibration traceability for clinical centrifuges). Optional audit trail module enables 21 CFR Part 11–compliant electronic records for FDA-regulated environments.

Software & Data Management

Embedded firmware supports method-based operation with up to 99 programmable protocols, each storing speed, time, temperature, acceleration/deceleration ramp rates, and auto-cap-removal activation status. All runs generate timestamped log files (CSV export via USB 2.0 port) containing start/stop times, actual RCF, rotor ID, temperature history, and cap-removal event flags. Optional Xiangyi LabLink™ PC software provides remote monitoring, fleet management, and integration with LIS/HIS systems via HL7 v2.5 or ASTM E1384 interfaces. Audit trails include user ID, parameter changes, and system alerts—fully compliant with GLP documentation requirements.

Applications

• Routine serum/plasma preparation in hospital core labs and reference laboratories
• Pre-analytical automation for immunoassay, clinical chemistry, and coagulation testing platforms
• Viral load sample prep where minimal mechanical disturbance post-centrifugation is critical
• Blood bank operations requiring high-volume, low-risk handling of donor samples
• Research applications involving large organelle isolation (e.g., mitochondria, lysosomes) from peripheral blood mononuclear cells (PBMCs)

FAQ

What temperature range does the CTK80R maintain during operation?
The unit maintains a stable refrigerated environment between 4 °C and 25 °C, with default pre-cooling set to 4 °C prior to run initiation.
Is rotor calibration traceable to national standards?
Yes—each rotor carries a unique serial number and factory calibration certificate traceable to CNAS-accredited metrology institutes per ISO/IEC 17025.
Can the cap-removal function be disabled for non-vacuum tube applications?
Yes—the cap-removal actuator can be deactivated via software setting, allowing use with standard conical tubes or microcentrifuge tubes using compatible adapters.
Does the system support preventive maintenance scheduling?
Built-in service timer tracks operational hours and prompts scheduled maintenance (e.g., refrigerant pressure check, rotor inspection) at configurable intervals (default: 1000 h).
What safety certifications apply to the CTK80R?
Certified to IEC 61010-1:2010 (Safety Requirements for Electrical Equipment), IEC 61010-2-020:2016 (Particular Requirements for Centrifuges), and CE-marked under EU Machinery Directive 2006/42/EC.
