Why the Multi-Disc platform stands out in decentralized diagnostics:


✅ Closed-Chip Full Automation | Zero Manual Processing

The system automates two gold-standard molecular diagnostic workflows — silica membrane-based nucleic acid extraction and real-time quantitative PCR — entirely within a single enclosed disposable microfluidic cartridge.

This "load-and-go" design requires only 1 minute of hands-on pipetting, with no additional sample preparation, reagent configuration or manual intervention throughout the testing process. The fully sealed cartridge structure eliminates aerosol cross-contamination risks at the source, reduces laboratory quality control burdens, and ensures consistent, reliable results even when operated by non-specialist staff after brief training. It makes high-standard molecular testing accessible to facilities of all sizes, from tertiary ICUs to primary care/community-level clinics.

✅High-Multiplex Syndromic Testing | Up to 28 Targets

Each microfluidic chip integrates 7 independent qPCR amplification chambers, paired with 4 high-sensitivity fluorescence channels.

This architecture enables simultaneous qualitative detection of up to 28 distinct pathogens and antimicrobial resistance genes from a single patient sample. Adopting a syndromic testing approach, it identifies both single and mixed infections in one run, eliminating the need for sequential repeated testing. It enables clinicians to rapidly clarify the etiology of severe infections, shift from empiric therapy to targeted antimicrobial treatment, reduce unnecessary antibiotic use, and curb the spread of antimicrobial resistance.


✅10 Ready-to-Use Panels Across Full Clinical Indications

The Multi-Disc platform is equipped with 10 pre-developed, CE-compliant detection panels, covering the full spectrum of common infectious disease scenarios in inpatient and public health settings:


26 Upper Respiratory Tract Pathogen Nucleic Acid Detection Kit (Fluorescent PCR-Chip Method);

23 Lower Respiratory Tract Pathogen and Antimicrobial Resistance Gene Nucleic Acid Detection Kit (Fluorescent PCR-Chip Method);

Meningitis Pathogen Nucleic Acid Detection Kit (18 targets, Fluorescent PCR-Chip Method);

26 Gastrointestinal Tract Pathogen Nucleic Acid Detection Kit (Fluorescent PCR-Chip Method);

25 Blood Culture Pathogen and Antimicrobial Resistance Gene (G+&Fungi&AMR) Nucleic Acid Detection Kit (Fluorescent PCR-Chip Method);

Blood Culture Pathogen and Antimicrobial Resistance Gene (G-&AMR) Nucleic Acid Detection Kit (26 targets, Fluorescent PCR-Chip Method);

10 Reproductive Tract Pathogen Nucleic Acid Detection Kit (Fluorescent PCR-Chip Method);

Human Papillomavirus (HPV) Nucleic Acid Typing Detection Kit (15 targets, Fluorescent PCR-Chip Method);

8 Arboviral Pathogen Nucleic Acid Detection Kit (Fluorescent PCR-Chip Method);

4 Malaria Pathogen Nucleic Acid Detection Kit (Fluorescent PCR-Chip Method).


✅ Flexible Throughput for All Scenarios

The instrument supports simultaneous testing of up to 4 samples per run, with flexible 1–4 sample loading configurations — no batch sample accumulation is required, and samples can be tested immediately upon arrival.

Full results are available in around 80 minutes, balancing speed and batch processing capacity. This scalability perfectly adapts to varying daily sample volumes, from stat emergency testing and outpatient ward diagnosis to on-site outbreak screening and routine inpatient batch testing.

Core Technological Breakthroughs


The Multi-Disc platform is built on four self-developed core technologies, delivering benchmark-level detection performance while lowering the threshold for molecular testing deployment:


✅Proprietary Centrifugal Microfluidic System

We creatively apply centrifugal microfluidic technology to integrate column-based nucleic acid extraction and ultra-multiplex qPCR reactions on a single fan-shaped chip. By precisely controlling the rotation speed and direction of the microfluidic chip, and combining capillary valves, siphon valves, phase-change valves, and pneumatically assisted capillary valves, the system sequentially delivers samples, lysis buffers, wash buffers and elution buffers to automatically complete nucleic acid extraction and purification, ensuring extraction quality and detection sensitivity on par with centralized laboratory gold-standard methods.

✅Lyophilized Reagent Pre-embedding Technology

With our self-developed PCR reagent lyophilization process, we pre-embed stable lyophilized reagent beads in the microfluidic chip during production. This design enables room-temperature storage and transportation of all detection kits, eliminating reliance on cold chain logistics, and greatly reducing storage and distribution costs for facilities, especially remote sites and field testing scenarios.


✅High-Consistency Mass Manufacturing Process

For large-scale production, we adopt one-step injection molding and laser surface welding technology (replacing traditional laser line welding). This process improves chip sealing performance and batch-to-batch consistency, reduces production costs, and ensures stable, uniform product performance during large-scale supply.


✅High-Precision Optical & Temperature Control System

Equipped with 4 independent fluorescence channels and a high-precision temperature control module with ±0.5°C accuracy, the system supports real-time dynamic fluorescence detection. This guarantees high specificity and sensitivity for ultra-multiplex target detection, delivering accurate and reliable diagnostic results.

Clinical & Application Scenarios


✅Tertiary Hospital Severe Care

Ideal for deployment in intensive care units (ICUs), neurology wards, respiratory departments, hematology departments and infectious disease wards of tertiary hospitals, supporting rapid etiological diagnosis of severe infections such as sepsis, severe pneumonia, meningitis and infectious diarrhea. It shortens the waiting time for targeted antimicrobial therapy and reduces mortality in critically ill patients.


✅Nosocomial Infection Control

Supports rapid screening of drug-resistant pathogens such as carbapenem-resistant Enterobacterales (CRE), methicillin-resistant Staphylococcus aureus (MRSA), Clostridioides difficile and Candida auris, enabling timely implementation of infection control measures to curb nosocomial cross-transmission.

✅Public Health Emergency Response

Suitable for on-site rapid testing in foodborne disease outbreaks, respiratory infectious disease epidemics, port entry-exit quarantine and tropical disease screening, helping to rapidly identify the source of infection and contain epidemic spread.


✅Primary care/community-level Healthcare

Enables molecular diagnostic capacity building in community hospitals, physical examination centers and medical institutions in remote areas, without the need to build standardized PCR laboratories, expanding access to high-quality precision testing.
