Ebaiao Zhongruihuxin Fully Automated Blood Aliquoting Workstation

Overview

The Ebaiao Zhongruihuxin Fully Automated Blood Aliquoting Workstation is an integrated benchtop platform engineered for precision, reproducibility, and regulatory-compliant pre-analytical sample processing in clinical and research laboratories. It employs vision-guided liquid handling combined with dual-sensor (pressure + capacitance) pipette tip detection to autonomously identify tube barcodes, detect plasma/buffy coat/erythrocyte layer interfaces in anticoagulated whole blood, and perform stratified aspiration and aliquoting into SBS-standard cryovials. Designed around the principle of traceable, unidirectional sample flow, the system executes end-to-end automation—from primary tube scanning and interface recognition to aliquot dispensing, cryovial barcode registration, and audit-ready data logging—without manual intervention. Its architecture supports ISO 15189 and CLIA-aligned workflows, ensuring alignment with Good Laboratory Practice (GLP) and pre-analytical quality assurance requirements for biobanking, diagnostic testing, and translational research.

Key Features

• Dual independent robotic arms enabling concurrent cap opening, pipetting, and plate transfer—eliminating process bottlenecks and cross-contamination risk
• Vision-based multi-layer interface detection algorithm trained on native whole blood morphology; validated across EDTA, citrate, and heparin anticoagulants
• High-fidelity barcode reading engine supporting 1D/2D codes on both tube sidewalls and cryovial bases; up to 16 cryoboxes scanned simultaneously (side + bottom QR)
• Smart liquid sensing: real-time pressure and capacitive detection for bubble, clot, or insufficient volume events—triggering automatic pause and operator alert
• Intelligent error prevention logic: detects missing or duplicate transfers via real-time volume reconciliation and positional verification
• Optional HEPA filtration (ISO Class 5) and UV-C irradiation module (254 nm) for laminar airflow control and surface decontamination between runs
• Modular design accommodating variable-height vacuum blood collection tubes (13 × 75 mm to 16 × 100 mm) and SBS-format cryovials (0.5 mL to 2.0 mL)

Sample Compatibility & Compliance

The workstation processes whole blood, plasma, buffy coat, and packed red blood cells from standard vacuum collection tubes (e.g., BD Vacutainer®, Greiner Bio-One). It maintains sample integrity through temperature-stable pipetting (ambient operation with optional refrigerated deck integration) and minimizes shear stress via low-speed aspiration protocols. All hardware and software modules comply with IEC 61000-4 electromagnetic compatibility standards and meet CE marking requirements for in vitro diagnostic (IVD) ancillary equipment. Audit trails include timestamped operator actions, sensor logs, barcode validation records, and environmental status flags—supporting FDA 21 CFR Part 11 electronic record/electronic signature readiness when deployed with validated LIMS integration.

Software & Data Management

The embedded control software provides role-based access control (RBAC), configurable SOP-driven protocols, and full digital audit trail generation compliant with ISO/IEC 17025 documentation requirements. Raw data—including pipette pressure curves, image snapshots of layer interfaces, and barcode decode confidence scores—are stored locally with optional encrypted cloud backup. An open RESTful API enables bidirectional communication with LIS, HIS, or biobank management systems (e.g., OpenSpecimen, LabVantage), allowing automatic sample registration, inventory update, and QC flag propagation. All data exports conform to MIAME and ISA-Tab metadata standards for seamless integration into omics data pipelines.

Applications

This workstation serves high-volume pre-analytical operations in blood banks, hospital central labs, CDC regional reference facilities, and academic core facilities conducting large-cohort studies (e.g., UK Biobank-style initiatives). In biopharma, it supports GMP-aligned raw material qualification for cell therapy manufacturing—particularly in autologous CAR-T and plasma-derived therapeutics where consistent plasma yield and minimal RBC carryover are critical. Vaccine developers utilize its stratified separation capability for antigen stability assessment across blood fractions, while infectious disease researchers deploy it for serial dilution and biobank curation of serological specimens under BSL-2 containment conditions.

FAQ

Does the system support integration with existing laboratory information systems?
Yes—it offers a documented RESTful API with JSON payload support for seamless two-way synchronization with LIS, HIS, and biobank platforms.

Can the workstation handle clotted blood samples?
No—it is optimized for anticoagulated whole blood only; serum separation requires centrifugation prior to loading.

What maintenance is required for long-term accuracy?
Quarterly calibration using gravimetric verification per ISO 8655-6; annual optical alignment check of the layer-detection camera system.

Is remote monitoring available?
Yes—real-time status dashboard and email/SMS alerts for error conditions, consumables depletion, or protocol completion are supported via optional network configuration.

How is data security ensured during transmission and storage?
All network communications use TLS 1.2+ encryption; local database encryption follows AES-256 standards; audit logs are write-once and immutable post-generation.
