Overview
The Xiangyi CTK150R Automatic Cap-Removal Refrigerated Centrifuge is an integrated laboratory solution engineered for high-throughput clinical hematology workflows where vacuum blood collection tubes (e.g., EDTA, serum separator, heparin tubes) are routinely processed. Unlike conventional centrifuges requiring manual cap removal post-spin—a step prone to operator-induced re-suspension, aerosol generation, and biohazard exposure—the CTK150R incorporates a fully automated cap-removal mechanism synchronized with the centrifugation cycle. It operates on a horizontal rotor architecture utilizing fixed-angle or swing-out configurations optimized for standard 13 mm × 75 mm and 13 mm × 100 mm vacuum tubes. Temperature control is maintained between –20 °C and +40 °C via a dual-stage refrigeration system with independent compressor and Peltier-assisted pre-cooling, ensuring sample integrity during prolonged runs. The device complies with IEC 61010-2-020 (safety requirements for centrifuges) and supports GLP-aligned operational traceability through embedded event logging.
Key Features
- Automated cap-removal module with >90% success rate across two standardized tube lengths (75 mm and 100 mm), eliminating manual handling and minimizing cross-contamination risk
- Refrigerated operation with precise temperature regulation (±0.5 °C accuracy) and rapid pre-cool capability (≤15 min from ambient to –10 °C)
- AC brushless frequency-controlled motor delivering stable rotational control (±10 rpm at 4000 rpm) and programmable acceleration/deceleration profiles
- Intelligent RCF calculation in real time based on rotor radius and actual speed; values displayed alongside rpm and time
- Passive-damping suspension system with self-balancing algorithm—detects mass asymmetry up to ±5 g per bucket and compensates dynamically without interrupting spin
- Electromechanical door interlock conforming to EN 61010-1:2010; centrifuge remains inert if lid is unlatched, and triggers immediate rotor deceleration upon forced opening during operation
Sample Compatibility & Compliance
The CTK150R accommodates common clinical vacuum tubes—including BD Vacutainer®, Greiner Bio-One, and Sarstedt formats—without adapter modification. Its rotor geometry ensures uniform radial force distribution across all six positions (6 × 25 mL capacity), enabling reproducible phase separation of whole blood into serum/plasma and cellular fractions. The instrument meets ISO 13485:2016 design controls for in vitro diagnostic (IVD) support equipment and aligns with CLSI GP45-A4 guidelines for centrifugal separation in clinical laboratories. All internal surfaces contacting samples or caps are constructed from medical-grade stainless steel (AISI 316L), passivated and corrosion-resistant to common anticoagulants and disinfectants.
Software & Data Management
The CTK150R features a 7-inch capacitive touchscreen interface with multi-language support (English, Spanish, French, Arabic). Protocols are stored locally (up to 100 user-defined programs), each including speed, time, temperature, acceleration ramp, and cap-removal timing parameters. Audit trail functionality records timestamped events: start/stop, temperature deviations, door status transitions, error codes, and cap-removal confirmation signals. Data export is supported via USB 2.0 port in CSV format, compatible with LIMS integration. While not FDA 21 CFR Part 11–certified out-of-the-box, the firmware architecture supports electronic signature implementation and role-based access control when deployed within validated IT environments.
Applications
- Routine serum/plasma preparation for clinical chemistry, immunoassay, and coagulation testing
- Pre-analytical processing in biobanking workflows involving large-volume peripheral blood mononuclear cell (PBMC) isolation
- High-volume hospital core labs performing >500 daily CBC and metabolic panel tests
- Reference laboratories requiring consistent hematocrit determination and platelet-poor plasma generation
- Viral load sample prep where cold-chain integrity and minimal mechanical disturbance are critical prior to nucleic acid extraction
FAQ
Does the CTK150R support rotor interchangeability with other Xiangyi models?
No—rotors are model-specific and mechanically keyed to prevent incorrect installation. Only certified CTK150R-compatible rotors (e.g., H150-6×25) may be used.
What maintenance intervals are recommended for the cap-removal actuator?
The pneumatic cap-lifter assembly requires visual inspection every 500 cycles and lubrication of linear guides every 2000 cycles using ISO VG 22 synthetic grease.
Can the unit operate without refrigeration enabled?
Yes—refrigeration can be disabled independently while retaining full centrifugation functionality, allowing ambient-temperature protocols for heat-stable analytes.
Is remote monitoring or Ethernet connectivity available?
Not natively; however, optional RS-485 serial output enables connection to building management systems or centralized lab monitoring platforms via Modbus RTU protocol.
How is calibration verified for RCF and temperature accuracy?
RCF verification requires third-party tachometer and radius measurement per ISO 21501-4; temperature calibration follows ASTM E74-22 using NIST-traceable PT100 probes placed at rotor cavity center.
