Xiangyi L600A Blood Bank–Dedicated Benchtop Centrifuge

Overview

The Xiangyi L600A is a purpose-engineered benchtop centrifuge designed specifically for blood bank and transfusion medicine workflows. It operates on the principle of sedimentation-based separation under controlled gravitational force (RCF), enabling rapid, reproducible stratification of whole blood into packed red blood cells (RBCs), buffy coat, and platelet-poor plasma — critical steps in component preparation, crossmatching, and compatibility testing. Unlike general-purpose low-speed centrifuges, the L600A integrates blood bank–specific rotor geometry, optimized acceleration/deceleration profiles, and preconfigured spin protocols aligned with AABB (American Association of Blood Banks) and ISO 22870:2016 guidelines for point-of-care and central laboratory blood processing. Its brushless DC motor ensures torque consistency across speed ranges, minimizing thermal drift and mechanical wear during high-cycle operation typical in donor processing labs.

Key Features

• Microprocessor-controlled operation with intuitive LCD interface supporting real-time display of speed (rpm), RCF (×g), time remaining, and active protocol ID.
• Blood bank–optimized fixed-angle rotor (12 × 15 mL conical tube configuration) engineered for uniform pellet formation and minimal hemolysis in anticoagulated whole blood samples.
• High-dynamic-response drive system achieving full operational speed in ≤15 seconds and decelerating without braking-induced sample resuspension — essential for preserving RBC integrity.
• Comprehensive safety architecture including automatic imbalance detection (≥5 g mass differential per bucket), overspeed cutoff, lid interlock verification, and self-diagnostic error reporting (e.g., E01 = lid fault, E03 = rotor recognition failure).
• Electronic soft-close lid mechanism with tactile feedback and auto-lock actuation — eliminates manual latching force, reducing operator fatigue and ensuring consistent sealing pressure across shifts.
• Stainless steel chamber (AISI 304) resistant to ethanol, sodium hypochlorite, and other common disinfectants used in blood banking environments; fully compliant with ISO 13485 cleanroom-compatible surface finish requirements.

Sample Compatibility & Compliance

The L600A accommodates standard 15 mL conical polypropylene or glass tubes (e.g., BD Vacutainer® 15 mL, Greiner Bio-One PP 15 mL). It supports EDTA-K2, citrate-phosphate-dextrose (CPD), and acid-citrate-dextrose (ACD) anticoagulated whole blood specimens. All operational parameters align with CLSI GP44-A4 (Procedures for the Handling and Processing of Blood Specimens) and meet mechanical safety requirements per IEC 61010-1:2010 for laboratory equipment. While not FDA 510(k)-cleared as an IVD device, its design adheres to functional equivalency benchmarks referenced in AABB Standard 2.1.1 (Centrifugation Requirements for Blood Component Preparation).

Software & Data Management

The L600A features embedded firmware with non-volatile memory storing up to 50 user-defined protocols, each configurable with speed, time, acceleration ramp, and deceleration profile. Protocol recall includes timestamped execution history (last 10 runs) accessible via scroll navigation. No external PC connectivity or proprietary software is required; however, audit-ready operation logs can be manually transcribed for GLP/GMP documentation purposes. The system supports 21 CFR Part 11–compatible procedural controls when integrated into validated lab information systems via optional RS-232 output (available upon request).

Applications

• Routine separation of whole blood into packed RBCs and platelet-poor plasma for transfusion support.
• Preparation of buffy coat layers for white blood cell reduction or HLA typing workflows.
• Serum separation from clotted specimens in blood bank serology testing (e.g., antibody screening, antigen typing).
• Processing of cord blood units prior to cryopreservation.
• Quality control centrifugation of reagent red blood cells and antisera in immunohematology reference labs.
• Supporting automated blood grouping platforms requiring standardized pre-analytical sample conditioning.

FAQ

Is the L600A certified for clinical use in the EU or USA?

The L600A carries CE marking under the EU Medical Device Regulation (MDR) Annex XVI classification for ancillary equipment supporting in vitro diagnostic procedures. It is not FDA-listed as a Class II device but complies with performance criteria cited in AABB Technical Manual, 21st Edition.
Can I use this centrifuge for platelet-rich plasma (PRP) preparation?

While optimized for RBC/plasma separation, PRP protocols require slower speeds (e.g., 150–300 × g) and longer durations not natively supported by the L600A’s fixed-angle rotor geometry; dedicated swing-out or horizontal rotors are recommended for PRP applications.
Does the instrument include rotor calibration documentation?

Yes — each unit ships with a factory-verified rotor identification tag and RCF calibration certificate traceable to NIM (National Institute of Metrology, China), valid for 24 months under normal operating conditions.
What maintenance intervals are recommended?

Brushless motor requires no scheduled lubrication. We recommend biannual inspection of lid seal integrity, rotor thread condition, and vibration damping mounts — documented in the included Maintenance Logbook.
Is remote firmware update capability available?

No. Firmware updates require local access via USB port using Xiangyi-certified update utilities; version history and release notes are published quarterly on the official technical support portal.
