Ruixin NCD-96DY Animal Disease Immunoassay Analyzer

Overview

The Ruixin NCD-96DY Animal Disease Immunoassay Analyzer is a CE-marked, 96-well microplate-based photometric analyzer engineered for high-throughput serological and antigenic detection in veterinary diagnostics laboratories. It operates on the standardized enzyme-linked immunosorbent assay (ELISA) principle—measuring optical density (OD) changes induced by enzymatic color development following specific antigen–antibody binding. Designed for regulatory-compliant workflows in food safety surveillance, livestock health monitoring, and zoonotic disease screening, the instrument delivers traceable, reproducible absorbance measurements across a broad spectral range (400–1100 nm), supporting both qualitative binary classification (positive/negative) and quantitative concentration determination. Its architecture adheres to core metrological requirements for clinical immunoassays—including photometric linearity (±0.1% up to 2.0A), inter-channel uniformity (≤0.02A), and thermal drift control (≤0.005A/hour)—ensuring consistency across multi-day batch testing and inter-laboratory comparisons.

Key Features

• True-color 7-inch capacitive touchscreen (800 × 480 resolution) with Windows-based GUI and full Chinese/English bilingual interface for intuitive protocol navigation and real-time status feedback.
• Self-calibrating 8-channel optical path with factory-aligned quartz halogen light source; automatic lamp dimming during idle periods extends service life beyond 2,000 hours.
• Motorized filter wheel accommodating up to 10 interference filters; standard set includes 405 nm, 450 nm, 492 nm, and 630 nm—optimized for common ELISA substrates (TMB, OPD, ABTS).
• Dual-wavelength and dual-read modes (single/double well) enable background subtraction and matrix interference correction per ANSI/CLSI EP10-A3 guidelines.
• Flexible plate mapping: users define control, standard, and sample positions in horizontal or vertical orientation—supporting WHO-recommended calibration layouts (e.g., 3×3 standard dilution series).
• Embedded thermal printer (optional external USB/LAN printer support) outputs GLP-compliant reports with timestamp, operator ID, plate ID, curve fit parameters, and pass/fail flags per test run.
• Onboard storage retains ≥105 full plates (≥100,000 individual OD values); all data exportable via USB or RS-232 to secure laboratory information systems (LIS) in native Excel (.xlsx) format.

Sample Compatibility & Compliance

The NCD-96DY accepts standard 96-well polystyrene microplates (flat-bottom, U/V-bottom) from major suppliers (Corning, Thermo Fisher, Greiner). It supports all commercially available veterinary ELISA kits validated under OIE standards—including those for Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), Avian Influenza H5N1, Mycoplasma gallisepticum, and Brucella abortus. Instrument performance meets ISO 15197:2013 accuracy thresholds for quantitative immunoassays and aligns with CLSI EP12-A2 verification protocols for qualitative test systems. Firmware implements configurable audit trails, electronic signatures, and user-access levels—enabling compliance with FDA 21 CFR Part 11 when paired with Ruixin ELISA Manager software (v3.2+), which logs all parameter modifications, calibration events, and result exports with immutable timestamps.

Software & Data Management

Ruixin ELISA Manager (Windows 10/11 compatible) provides centralized control of instrument operation, method deployment, and statistical review. The software stores up to 200 customizable assay protocols—including wavelength selection, incubation timing, curve-fitting algorithms (9 models), and decision logic for cut-off calculations (e.g., S/CO, P/N ratios). All raw absorbance data are archived with metadata (date/time, operator, lot numbers, environmental temperature/humidity if logged externally). Export modules generate PDF reports compliant with ISO/IEC 17025 documentation requirements, including uncertainty estimation per GUM (Guide to the Expression of Uncertainty in Measurement) principles. Data integrity safeguards include role-based permissions, automated backup to network drives, and SHA-256 hash verification of exported datasets.

Applications

The NCD-96DY serves as a primary screening platform in national veterinary reference laboratories, abattoir quality assurance units, feed mill QC departments, and academic research facilities conducting host-pathogen interaction studies. Validated use cases include: surveillance of swine respiratory disease complexes (PRRSV, PCV2, Mycoplasma hyopneumoniae); avian influenza subtyping (H5/H7/H9); detection of zoonotic agents (Brucella spp., Toxoplasma gondii, Trichinella spiralis); residue monitoring (tetracyclines, sulfonamides, β-lactams) in animal tissues; and seroepidemiological mapping of vaccination coverage in cattle herds. Its rapid turnaround (<3 min per plate) and multi-analyte capability reduce reliance on centralized PCR labs—accelerating outbreak response times while maintaining analytical rigor.

FAQ

Does the NCD-96DY support third-party ELISA kits?
Yes—it is fully compatible with all CE-IVD and USDA-licensed veterinary ELISA kits requiring absorbance readout at 405 nm, 450 nm, 492 nm, or 630 nm.
Can the instrument be integrated into an existing LIS or LIMS?
Yes—via RS-232 serial output or USB virtual COM port using ASTM E1384 or HL7-compatible ASCII data packets.
What calibration standards are required for routine verification?
NIST-traceable neutral density filters (OD 0.5, 1.0, 2.0) and potassium dichromate solutions per ISO 6726 are recommended for quarterly photometric validation.
Is remote firmware update supported?
Firmware updates are performed offline via USB flash drive; no internet connectivity is required to maintain air-gapped laboratory security.
How is data integrity ensured during power interruption?
Non-volatile flash memory preserves active assay progress and unsaved results; system resumes from last stable state upon reboot without data loss.
