Introduction
The automated sample processing system is compatible with a biological safety cabinet and automates lid opening/closing, dispensing, and addition of proteinase K/internal controls to accelerate high-throughput nucleic acid sample pre-processing in clinical and research laboratories.

Application

• Sample preparation for clinical diagnostics
• Epidemic surveillance
• Food safety testing
• Forensic identification
• Scientific research
• Suitable for SARS-CoV-2 and other virulent infectious disease samples

Working process
The system performs automated lid handling, reagent dispensing, and additive delivery (e.g., proteinase K or internal controls) and coordinates multiple stations to optimize high-throughput pre-analytical workflows within a biosafety cabinet.

Features

• Safety: Built-in UV lamp and design compatible with biological safety cabinets to reduce aerosol contamination.
• Efficiency: Cooperative processing with single or dual robotic arms depending on model.
• Usability: Visual interface and one-key operation for straightforward use.
• Compatibility: Accepts multiple pipette tips, deep-well plates and various sampling tubes (including blood collection tubes).
• Smart functions: Pneumatic liquid-level detection and blocked-needle detection; intelligent dispensing.
