Antibiotic residue monitoring is a non-negotiable requirement in modern dairy production. With strict Maximum Residue Limits (MRLs) enforced across domestic and export markets, Australian dairy processors must ensure that raw milk entering the supply chain is free from prohibited or excess antibiotic residues.
For laboratories and dairy plants seeking a reliable dairy testing kit in Australia, the COMET32 system offers automated, high-throughput screening of more than 50 antibiotics in a single assay—combining microbiological reliability with digital traceability.
Why Antibiotic Screening in Milk Is Critical
Antibiotics are widely used in dairy farming to treat and prevent infections such as mastitis. However, milk containing residues above regulated thresholds can:
- Fail compliance testing
- Disrupt fermentation processes
- Damage export eligibility
- Trigger product recalls
- Harm brand credibility
Australia’s dairy industry exports billions of dollars’ worth of product annually, meaning residue compliance is not just a safety issue—it is a commercial imperative.
Routine screening must therefore be:
- Broad-spectrum
- Sensitive
- Standardised
- Fast
- Fully traceable
COMET32 is designed to meet these operational and regulatory demands.
What Is COMET32?
COMET32 is an autonomous screening system designed to work with ZEULAB microtiter plate tests for detecting antibiotic residues in milk.
It enables the automatic screening of more than 50 antibiotics in milk in a single assay, significantly simplifying routine residue monitoring.
The system is suitable for:
- Raw milk testing
- Dairy plant intake control
- Central laboratory verification
How COMET32 Works
The system integrates incubation, optical monitoring, and digital interpretation into one compact platform.
Step 1: Incubation
COMET32 incubates microtiter plate tests at controlled temperatures:
These conditions support bacterial growth-based detection methods used in microbiological residue tests.
Step 2: Real-Time Monitoring
The system measures color changes in real time, tracking bacterial growth kinetics.
When antibiotics are present, bacterial growth is inhibited, altering the expected color development. COMET32 continuously monitors this reaction.
Step 3: Automated Interpretation
Internal software integrates:
- Time parameters
- Color development curves
The system automatically determines the endpoint of the assay and interprets results without manual subjectivity.
Step 4: Digital Output & Traceability
Results are:
- Displayed on a touch and colour screen
- Stored digitally
- Accessible via USB connection
This ensures full traceability and audit-ready documentation.
Key Technical Specifications
COMET32 is engineered for both laboratory and plant environments:
- Number of samples per run: 32
- Outer dimensions: 305 × 305 × 96 cm
- Weight: 3 kg
- Working temperatures: 63°C ± 1°C / 37°C ± 1°C
- Interface: USB
- Screen: Touch and colour display
The 32-sample capacity supports batch efficiency while maintaining controlled incubation conditions.
Operational Advantages for Dairy Testing in Australia
1. Broad Antibiotic Coverage
Screening more than 50 antibiotics in a single assay reduces the need for multiple targeted tests. This enhances operational efficiency and broad-spectrum risk coverage.
2. Standardised Testing
Manual microbiological assays can be subject to interpretation variability. COMET32 automates incubation and result analysis, improving consistency.
3. Real-Time Kinetic Monitoring
Rather than relying on fixed endpoint observation alone, the system tracks bacterial growth kinetics. This improves reliability and reduces false interpretations.
4. Improved Throughput
Testing 32 samples simultaneously makes it suitable for high-volume dairy intake points.
5. Full Traceability
Digital storage of results supports:
- Audit readiness
- Regulatory compliance
- Quality assurance documentation
Who Should Use COMET32?
Dairy Processing Plants
- Intake testing of raw milk tankers
- Rapid screening before unloading
- Protecting starter cultures used in fermentation
Dairy Laboratories
- Routine antibiotic monitoring
- Export compliance verification
- Confirmatory workflow support
By integrating automated screening at intake, plants can prevent contaminated batches from entering production—avoiding costly downstream losses.
Protecting Fermentation and Product Integrity
Antibiotic residues can inhibit starter cultures used in:
- Cheese production
- Yoghurt manufacturing
- Cultured dairy products
Even trace residues can disrupt fermentation kinetics, leading to:
- Texture defects
- Off-flavours
- Production losses
Early detection at the raw milk stage protects process stability and finished product quality.
Supporting Compliance in the Australian Dairy Sector
The Australian dairy industry operates under stringent regulatory frameworks and export standards. Rapid, automated screening supports:
- Hazard Analysis and Critical Control Points (HACCP) systems
- Supplier quality verification
- Risk-based monitoring programs
- Export certification requirements
A modern dairy testing kit in Australia must do more than detect residues—it must integrate into digital quality management systems. COMET32 delivers this combination of microbiological reliability and electronic traceability.
