Nucleic Acid Extraction Workstation

The nucleic acid extraction workstation is a fully‑automated, high‑throughput sample processing system based on magnetic‑bead‑based separation chemistry. It is designed for lysis, binding, washing, elution and purification of nucleic acids (DNA/RNA) from various starting materials including whole blood, plasma, serum, swabs, tissue lysates, cell suspensions and pathogen‑containing samples. The system performs closed‑tube processing to minimize cross‑contamination risk, delivers consistent nuclei

Product Advantages

  • I. Main Application Scenarios
  • Clinical and CDC Testing
  • Clinical laboratories of hospitals and CDCs conduct large-scale screening of respiratory, blood-borne and enteric pathogens (viral DNA/RNA). Direct loading is available for samples such as throat swabs, whole blood, serum, plasma and stool.
  • Forensic and Judicial Identification
  • Process challenging evidence including blood stains, seminal stains, hair, cigarette butts and buccal swabs. Extract trace DNA for STR genotyping and individual identification.
  • Scientific Research and Genomics
  • Genomic DNA / total RNA extraction from animal and plant tissues, cultured cells, FFPE sections and microorganisms for downstream NGS, qPCR and gene expression analysis.
  • Food / Environmental / Animal & Plant Quarantine
  • Detection of food-borne pathogens, enrichment of microorganisms in water and soil, entry-exit animal and plant quarantine, etc.

  • II. Key Technologies & Performance Specifications
    • ItemTypical Specifications & Requirements
    • Extraction Principle Magnetic bead method (magnetic rod transfers magnetic beads, no aspirate-dispensing separation). Compatible with mainstream commercial magnetic bead kits (open platform).
    • Sample Throughput Standard: 24 / 48 / 96 samples per run; high-throughput model supports 192 ~ 384 samples per batch. Random run of 1 to N samples is supported.
    • Applicable Sample Types Whole blood, serum, plasma, throat swabs, saliva, urine, stool, sputum, tissue homogenate, FFPE, bacterial/fungal culture medium, etc.
    • Processing Volume Sample aspiration volume: 20 ~ 1000 μL (large-volume model supports pre-processing of 2 ~ 8 mL); purification elution volume: 30 ~ 200 μL
    • Pipetting Precision CV ≤1%~3% (volume-dependent); equipped with liquid level sensing, clot/nozzle blockage alarm and missed aspiration detection
    • Magnetic Bead Recovery Rate ≥95% ~ 98%
    • Well-to-well Uniformity CV ≤3% ~ 5%
    • Temperature Control Module Heating for lysis/elution: Ambient temperature ~ 90/120°C; bottom wrapping heating for deep-well plates; temperature accuracy ≤±1°C
    • Oscillation & Mixing Adjustable amplitude and frequency in multiple gears to adapt to reagents of different viscosities
    • Contamination Prevention Built-in UV disinfection + HEPA negative pressure filtration (≥99.97%); disposable pipette tips / magnetic rod sleeves; enclosed cabin design to prevent aerosol spread
    • Extended Functions Automatic lid opening/closing; barcode scanning for sample ID binding; automatic dispensing and setup of PCR reaction systems; reagent refrigeration module (4°C)
    • Software & Data Management Graphical touchscreen interface; capable of storing 100 to hundreds of customized protocols; protocol import/export, LIS connection and run log traceability supported
  • Processing Duration Full workflow for 96 samples (including automatic loading and extraction): approx. 25 ~ 40 minutes
