Xiangyi CTK132C Automated Cap-Removal Benchtop Centrifuge

Overview

The Xiangyi CTK132C Automated Cap-Removal Benchtop Centrifuge is an integrated clinical laboratory solution engineered for high-throughput, standardized processing of vacuum blood collection tubes. Unlike conventional centrifuges requiring manual cap removal post-spin—introducing risks of sample remixing, aerosol generation, and operator exposure—the CTK132C performs fully automated cap detachment immediately after deceleration, enabling seamless transition to downstream analysis (e.g., clinical chemistry, immunoassay, or hematology workstations). Its operation follows the fundamental principle of sedimentation-based separation under controlled gravitational force (RCF), optimized for serum/plasma isolation from whole blood in evacuated tubes. Designed specifically for routine diagnostic laboratories operating under ISO 15189 and CLIA-aligned quality management systems, the CTK132C supports traceable, repeatable workflows while minimizing hands-on time and biosafety hazards.

Key Features

• Integrated cap-removal mechanism with >90% success rate across both 75 mm and 100 mm vacuum tubes (Ø13 mm diameter)
• Horizontal rotor configuration accommodating up to 132 tubes per run—optimized for standard clinical batch sizes
• Brushless AC frequency-controlled motor delivering precise speed regulation (±30 rpm) and rapid acceleration/deceleration profiles
• Intelligent auto-balance detection system compensating for minor tube mass discrepancies without manual rebalancing
• Dual-stage vibration damping architecture—including specialized shock absorbers and reinforced rotor housing—to maintain <62 dB(A) acoustic emission during operation
• Microprocessor-controlled temperature management (15–25 °C, ±2 °C accuracy) using eco-friendly refrigerant compressor
• Electronic interlocked safety door: centrifuge inhibits start-up if lid is unlatched; immediate rotor halt upon forced opening during run
• Large backlit LCD interface supporting intuitive parameter entry, real-time RCF calculation, and cycle progress visualization

Sample Compatibility & Compliance

The CTK132C accepts standard vacuum blood collection tubes conforming to ISO 6710 and CLSI GP41-A7 specifications, including EDTA, heparin, citrate, and serum separator tubes (SSTs) with diameters of Ø13 mm and lengths of either 75 mm or 100 mm. Its rotor assembly—including interchangeable adapters—is validated for mechanical integrity under repeated thermal cycling and load asymmetry conditions. The instrument complies with IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and meets electromagnetic compatibility standards per EN 61326-1. While not FDA 510(k)-cleared, its design aligns with principles referenced in CLSI EP05-A3 (Evaluation of Precision of Quantitative Measurement Procedures) and supports GLP-compliant documentation when paired with audit-trail-enabled LIMS integration.

Software & Data Management

The embedded firmware supports programmable protocols with user-defined timer settings (1 second to 99 minutes 59 seconds), speed ramping profiles, and automatic RCF recalculation based on real-time rotor radius input. All operational events—including start/stop timestamps, error codes, door status logs, and temperature deviations—are stored locally in non-volatile memory for retrieval via USB export. Though the base unit lacks network connectivity, its data structure is compatible with third-party laboratory information systems (LIS) through standardized CSV output. For regulated environments, optional firmware upgrade enables electronic signature support and 21 CFR Part 11–compliant audit trails when deployed with external authentication servers.

Applications

• Routine serum and plasma preparation in hospital core labs and reference testing facilities
• Pre-analytical automation for high-volume immunology and coagulation testing platforms
• Blood bank sample processing where tube integrity and clot retraction consistency are critical
• Clinical trial biobanking operations requiring standardized, low-vibration separation prior to aliquoting
• Point-of-care satellite labs needing compact, self-contained centrifugation with minimal infrastructure dependencies

FAQ

What tube formats does the CTK132C support?
It accommodates vacuum blood collection tubes with outer diameter Ø13 mm and lengths of either 75 mm or 100 mm—compatible with major global manufacturers’ product lines.
Is temperature control active during the cap-removal phase?
Yes; the compressor remains engaged throughout the full cycle—including post-centrifugation dwell and cap ejection—to preserve sample stability at setpoint.
Can the rotor be sterilized or cleaned in an autoclave?
No; the horizontal rotor assembly is not autoclavable. Cleaning must follow manufacturer-recommended procedures using 70% ethanol or neutral pH disinfectants—avoiding chlorine-based agents.
Does the system support remote monitoring or IoT integration?
Not natively; however, USB data export enables periodic synchronization with centralized lab analytics dashboards or preventive maintenance scheduling tools.
What safety certifications apply to this model?
It carries CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to IEC 61010-1:2010 Edition 3.0 for laboratory equipment safety.
