The quality of milk is the cornerstone of Australia’s dairy industry — a sector worth over $5.9 billion annually and producing more than 8 billion litres of milk each year. To maintain its reputation for purity and export readiness, Australia enforces strict residue monitoring programs to ensure that milk is free from antibiotic contamination before processing or sale.
That’s where Duplex BT Scan for the IRIS system, offered by Vendart Diagnostics, plays a vital role. This compact, reliable, and data-connected rapid test detects two of the most critical antibiotic families — β-lactams and tetracyclines — within just six minutes, empowering farmers, collectors, and processors to act before contaminated milk enters the supply chain.
Why Antibiotic Testing Matters in the Dairy Chain
Antibiotic residues are one of the biggest quality risks in milk production. Cows treated for infections such as mastitis are often given antibiotics, but if withdrawal times aren’t observed properly, traces can remain in milk.
According to Dairy Australia and Food Standards Australia New Zealand (FSANZ), any detection of antibiotic residues above the legal Maximum Residue Limits (MRLs) renders milk unfit for sale. A single contaminated tanker can lead to entire batch rejection, economic loss, and penalties for farmers.
That’s why having an on-site, easy-to-use dairy testing kit in Australia—like Duplex BT Scan—isn’t optional; it’s essential for operational safety and regulatory compliance.
What Is the Duplex BT Scan?
The Duplex BT Scan is a one-step, competitive immunochromatographic test designed for qualitative detection of two major antibiotic families in milk:
- β-lactams (β): include penicillins and cephalosporins, commonly used for treating bacterial infections.
- Tetracyclines (T): broad-spectrum antibiotics frequently used in livestock management.
With Duplex BT Scan, users simply:
- Add one drop of milk to the cassette.
- Insert it into the IRIS reader.
- Receive results automatically — both visually and via Wi-Fi, Bluetooth, or 4G, directly on mobile, server, or cloud.
This quick workflow enables seamless decision-making at the farm, tanker, or plant level.
How It Works — The Science Behind the Speed
The Duplex BT Scan leverages immunochromatography, a well-established method in rapid diagnostics. Here’s what happens inside the cassette:
The milk sample flows across a nitrocellulose membrane containing antibodies specific to β-lactam and tetracycline molecules.
If residues are present, they bind to these antibodies, preventing the formation of visible test lines.
The IRIS reader’s optical sensors then quantify this reaction automatically, converting it into a clear, objective digital result.
The result? A simple “positive” or “negative” reading in under 6 minutes — no lab, no reagents, and no human interpretation errors.

Assay Type: One-step competitive immunochromatographic test in cassette format.
Assay Time: Delivers results in just 6 minutes — ideal for rapid screening at farms, collection centers, or processing plants.
Results: Can be read visually or automatically via the IRIS reader, with results transmitted instantly through Wi-Fi, Bluetooth, or 4G.
Format Options: Available in 25-cassette and 100-cassette packs to suit both small- and large-scale operations.
Why Australian Dairy Processors Choose Duplex BT Scan
Real-Time Data Sharing
Once the IRIS unit completes the test, results are automatically uploaded to your cloud or server in real-time. This enables quality teams to monitor multiple sites simultaneously, ensuring traceability and transparency across the milk collection network.
Zero Guesswork
Unlike traditional colorimetric strip tests that rely on human interpretation, the Duplex BT Scan, paired with the IRIS optical reader, eliminates subjective bias. You get digital, repeatable results — essential for compliance documentation and audit trails.
On-Farm and In-Transit Control
Whether it’s a milk tanker en route to the processing facility or raw milk being collected from farms, operators can instantly verify contamination status. This minimises the risk of cross-contamination and costly batch rejections.
Fast, Simple, and Portable
With its 6-minute workflow and handheld IRIS device, testing can be done almost anywhere — farm gate, collection truck, or plant reception. No lab infrastructure required.
Compliance Made Easy
The Duplex BT Scan supports dairy producers in meeting standards set by Australian Milk Residue Analysis (AMRA) programs and FSANZ MRL guidelines, ensuring every litre meets Australia’s premium export standards.
The Role of Rapid Antibiotic Testing in Modern Dairy Operations
Rapid testing isn’t just about compliance; it’s about operational efficiency and consumer confidence.
Economic Protection: Avoid milk rejections and tanker penalties that can cost thousands of dollars per incident.
Process Efficiency: Integrate results with digital platforms for automatic alerts and traceability.
Sustainability: By detecting contamination early, producers reduce waste and improve resource utilisation.
In today’s competitive dairy landscape, having a smart, connected dairy testing kit in Australia like Duplex BT Scan gives producers a measurable advantage.
