This automated filling and capping production line is specifically designed for the sample processing tubes (comprising extraction tubes, sealing caps, and buffer solution components) used with antigen test kits. It integrates automatic tube feeding, precision quantitative filling, automatic cap sorting and placement, torque-controlled capping, and finished product discharge into a single system, enabling a fully automated, closed-loop process from empty tubes to sealed, finished products. The entire line complies with medical device GMP standards regarding cleanliness, precision, and traceability, serving as reliable equipment that helps in vitro diagnostic (IVD) reagent companies rapidly respond to market demands.
The production line organizes and aligns extraction tubes using an automatic feeding mechanism and sorting system. A precision transport system then sequentially handles quantitative filling (buffer/lysis solution), automatic cap placement, and precise torque capping before discharging the finished product to the next stage. The process requires no manual intervention and supports continuous, uninterrupted operation. A single operator can monitor the entire line, significantly reducing staffing requirements and labor intensity.
Built with a high-rigidity frame and a full servo-drive system, the line operates smoothly with rapid response times. The core filling unit utilizes high-precision ceramic piston pumps or valveless plunger pumps, achieving filling accuracy of ±0.5% to ±1.0% to ensure consistent solution volume in every tube. Critical contact parts are made of 316L stainless steel and corrosion-resistant materials, making them compatible with components such as buffers and surfactants. The capping unit features a high-precision torque control system, ensuring reliable sealing without damaging the threads. The equipment supports stable 7×24 hour operation with a filling defect rate of less than 0.2%, guaranteeing high batch-to-batch consistency.
Equipped with a PLC and industrial touchscreen, the system stores specifications for hundreds of tube types (diameter, capacity) and corresponding parameter recipes (fill volume, capping torque, speed), allowing for one-touch product changeovers. Built-in features include tube-absence detection, automatic refilling based on liquid level sensing, cap-absence alarms, and self-diagnostic systems; the machine automatically stops and triggers audio-visual alarms upon detecting anomalies. It also supports production data storage and MES integration, ensuring full traceability of the filling process.
With filling and capping speeds reaching 60–120 units per minute (depending on tube type and fill volume), a single machine can easily exceed a daily output of 100,000 units—delivering 8 to 10 times the efficiency of manual operations. The multi-station parallel design (featuring four, six, or eight filling heads) significantly accelerates production cycles while drastically reducing the risk of microbial and particulate contamination associated with human contact, ultimately cutting overall operating costs by more than 50%.
Centered on high-precision volumetric filling and accurate torque control, this automated production line ensures that the fill volume and sealing quality of every sample tube meet the rigorous standards required for both IVD (in vitro diagnostic) regulatory compliance and clinical testing. Leave behind the inconsistency and inefficiency of manual or semi-automated methods; choose this solution to ensure your antigen test products—characterized by uniform, high quality—rapidly reach the front lines of the global fight against the pandemic and health screening efforts.
