How to Choose Antigen Test Kit Filling-Capping Machines？

1. Critical Machine Configuration Factors

✅ Aseptic Filling Precision

• Opt for stainless steel ceramic piston pumps or peristaltic pumps to handle volatile reagents (e.g., protein-based buffers), ensuring ±1% dosing accuracy to minimize false test results caused by volume deviations.
• Prioritize nitrogen protection systems to prevent reagent oxidation in high-sensitivity COVID-19/IVD antigen kits.

✅ Throughput & Line Integration

• Match output to demand: 60-100 bottles/min configurations (adjustable via PLC) suit mid-scale diagnostic labs, while modular designs allow future scalability.
• Confirm compatibility with upstream/downstream equipment (e.g., vial washers, labeling systems) using Schneider electric components for synchronized control.

✅ GMP Compliance & Material Safety

• Select 316L stainless steel contact surfaces and FDA-grade silicones to avoid chemical leaching into reagents.
• Demand ISO 14644 Class 8 cleanroom validation reports to meet IVD manufacturing standards.

2. Supplier Evaluation Guidelines

 Industry-Specific Expertise

• Verify 10+ years of experience in IVD equipment, with case studies demonstrating successful antigen kit line integrations (request client references).

 Technical Support & Customization

• Ensure suppliers provide 24/7 multilingual support and adaptive engineering for unique vial formats (e.g., 10-30ml bottles common in rapid test kits).
• Check availability of spare parts kits (e.g., Transtecno motors, Schneider PLCs) to minimize downtime.

Certification Transparency

• Require CE, FDA 21 CFR Part 11, and GMP documentation, plus third-party validation protocols for audit readiness.

 Cost-Benefit Analysis

• Compare TCO (Total Cost of Ownership), including energy consumption (e.g., 3KW/h systems vs. higher-power alternatives) and maintenance fees.
