Cowin Gene NATBox System Mini II.
A portable, cartridge-based real-time PCR platform built for point-of-care molecular testing. Closed three-chamber cartridge integrates lysis, purification, and amplification — no dedicated molecular lab required. CE-IVD marked. Multi-pathogen menu spanning HPV, STI, respiratory, gastrointestinal, and tuberculosis.
A point-of-care molecular diagnostic platform performs nucleic acid testing — the same PCR-based technology used in high-throughput reference labs — but in a form factor and workflow that does not require a dedicated molecular biology laboratory. Sample lysis, nucleic acid purification, and real-time PCR amplification all occur inside a closed disposable cartridge. The instrument is small enough to sit on any clinic bench or be carried into the field. The operator is a clinician, midwife, or trained nurse — not necessarily a molecular technologist. The result is delivered in under two hours instead of overnight.
The NATBox cartridge is a closed three-chamber consumable. The lysate cavity receives the patient sample (swab, sputum, plasma, urine, etc.) and lyses cells to release nucleic acids. The purification cavity isolates the target nucleic acids from inhibitors and debris. The reaction cavity performs real-time fluorescence PCR — amplifying the target sequence and detecting fluorescent signal in real time. Because every step occurs in a sealed cartridge, the cross-contamination risk that limits open PCR workflows is structurally eliminated. There is no need for separate pre-PCR and post-PCR rooms, no need for HEPA-filtered laminar flow, no risk of amplicon carryover into the next sample.
The instrument itself is engineered for decentralization: handheld-class footprint at approximately 1.8 kg and 130×130×120 mm, runs on standard mains power, and uses a single touch-screen interface for scan-cartridge / load-sample / press-run operation. Sample-to-answer turnaround is 50–100 minutes depending on the assay. Each run accommodates 2 cartridges in parallel — sufficient for the throughput patterns of a women's health clinic, primary care centre, or field-deployed outreach team.
The reagent menu is broad. HPV genotyping for cervical cancer screening is the platform's flagship and most widely deployed application — multiple genotype panels are available, including the high-risk HPV 16/18 detection central to WHO's cervical cancer elimination strategy. The menu extends to STI multiplex panels, respiratory pathogens including SARS-CoV-2, influenza, and RSV, gastrointestinal pathogens, and Mycobacterium tuberculosis (MTB) and MTB+NTM detection cartridges. All cartridges are CE-IVD marked.
JHS Analytic Traders is the authorized Cowingene distributor in Nepal. We supply the NATBox instrument and reagent cartridges through manufacturer-authorized channels, with on-site installation, operator training, validation cartridges for commissioning, and ongoing technical and reagent supply across the country.
One Closed Cartridge. Three Chambers. Sample-to-Answer.
The NATBox cartridge integrates the entire molecular workflow inside a single sealed consumable. Once the sample is loaded, no operator intervention is required between extraction, purification, and amplification — and no sample or amplicon ever leaves the cartridge.
Lysate Cavity
Receives the patient sample — swab, sputum, plasma, serum, whole blood, CSF, urine, or other specimen. Lyses cells to release intracellular nucleic acids.
Purification Cavity
Isolates the target nucleic acids from inhibitors, proteins, and cellular debris. Delivers a clean, PCR-ready template downstream.
Reaction Cavity
Real-time fluorescence PCR — amplifies the target sequence and detects fluorescent signal in real time. Result automated by instrument software.

Clinical Settings & Use Cases
Women's Health & HPV Screening
Cervical cancer screening at primary care clinics, district hospitals, and women's health camps — same-visit HPV testing without referral to a reference lab.
District Hospitals
First molecular diagnostics capability for district hospitals that previously sent all samples to provincial or central labs.
Primary Care & OPD Triage
Same-visit STI and respiratory pathogen testing — diagnosis before the patient leaves the clinic, faster treatment decisions.
Rural & Outreach Programmes
INGO and government outreach in remote districts — molecular testing in mobile health camps where no laboratory exists.
Outbreak Response & Surveillance
Rapid field-deployable PCR for respiratory and GI outbreak investigation; surveillance programmes in border and high-risk areas.
Decentralized TB Triage
MTB / MTB+NTM detection in non-accredited primary and district settings — referral confirmation via WHO-prequalified platforms at reference labs.
The NATBox Is One Part of JHS's Molecular Diagnostics Portfolio.
Whether you're configuring a women's health clinic, building decentralized molecular capability across a hospital network, or scaling a National HPV Screening programme, JHS supplies the full chain — instruments, reagents, biosafety cabinets, sample storage, training, and ongoing technical support. The NATBox handles point-of-care molecular; reference-lab platforms cover high-throughput requirements.
What is the Cowin Gene NATBox System Mini II?
The Cowin Gene NATBox Mini II is a portable, cartridge-based real-time fluorescence PCR (NAAT) platform for point-of-care molecular diagnostics. A single closed three-chamber cartridge integrates sample lysis, nucleic acid purification, and real-time PCR amplification — eliminating the need for a dedicated molecular biology laboratory. The instrument is handheld-class (~1.8 kg, 130×130×120 mm) and delivers a result in 50–100 minutes from sample-in to answer-out, with one-touch operation requiring minimal training.
What pathogens does the NATBox Mini II test for?
The NATBox menu spans multiple infection categories. The flagship application is HPV genotyping for cervical cancer screening, with multiple genotype panels available (HPV 16/18, 16/18/45, 6/11, and broader high-risk panels). Additional menu items include STI multiplex, respiratory pathogens (SARS-CoV-2, influenza, RSV), gastrointestinal pathogens, and Mycobacterium tuberculosis (MTB) and MTB + NTM detection. Test cartridges are sold separately and are CE-IVD marked.
Is the NATBox WHO-prequalified for TB diagnosis?
No. The NATBox is not WHO-prequalified for tuberculosis diagnosis. Currently the only rapid molecular TB tests with WHO prequalification are Cepheid's Xpert MTB/RIF Ultra and Xpert MTB/XDR. The NATBox MTB cartridge is suitable for decentralized molecular TB testing in non-accredited and triage settings — primary health centres, district hospitals, and outreach programmes — but for accredited TB reference labs and National TB Programme procurement, WHO-prequalified platforms remain the primary recommendation.
Does the NATBox require a dedicated molecular biology lab?
No. The closed cartridge architecture eliminates the cross-contamination risk that drives the strict pre-PCR / post-PCR room separation conventional rt-PCR labs require. The NATBox can be deployed on any clinic bench, in primary care centres, in mobile health camps, and in field settings — with standard mains power and minimal infrastructure. This is the platform's core architectural advantage over conventional rt-PCR.
Where in Nepal is the NATBox best deployed?
The NATBox is purpose-built for decentralized point-of-care molecular testing — settings where sample transport to a central reference lab is not practical, where molecular biology infrastructure is not available, or where rapid on-site results are clinically required. In Nepal that includes: women's health and cervical cancer screening clinics (the flagship HPV use case), district hospitals running molecular diagnostics for the first time, primary care centres and outreach programmes in rural districts, INGO-funded health initiatives, and field deployment for outbreak response or surveillance.
Does JHS provide training, installation, and reagent supply?
Yes. As Cowingene's authorized distributor in Nepal, JHS Analytic Traders provides on-site installation, operator training (minimal — the platform is designed for one-touch operation), demonstration cartridges for validation, ongoing reagent and consumable supply through manufacturer-authorized channels, and technical support throughout the product lifecycle.
