In high-throughput laboratories, consistency at the capping stage is critical to preserving sample integrity and minimising downstream analytical risk.
HF’s Automated Capping System combines advanced machine vision, adaptive image recognition, and precision mechanical handling to deliver a fully autonomous capping process designed for demanding technical environments.
Key technical capabilities include:
- In-house developed image recognition platform, trainable for application-specific classification, orientation and detection tasks.
- Bulk lid loading directly from standard bags — eliminating manual sorting and pre-orientation.
- Rotary turntable feeder for lid singulation and indexed presentation into the inspection zone.
- Fixed camera architecture with controlled illumination for repeatable, high-accuracy image capture.
- Real-time orientation verification against trained reference geometry.
- Integrity screening for lid deformation, contamination and missing septa.
- Non-contact rejection via synchronised compressed air pulse, aligned with lid position through indexing signals.
- Closed-loop recirculation system that continuously reprocesses rejected lids until correct orientation is achieved.
- Automated pneumatic crimping for precise seating and secure vial closure.
- Continuous unattended operation from a single bulk load until every vial is correctly capped.
Engineered for Gas Chromatography and Karl Fischer analysis vials, the system is also fully retrainable for additional lid types and broader classification applications.
By integrating machine vision with adaptive automation, HF’s solution enhances throughput, reduces operator intervention and strengthens process reliability — delivering a smarter approach to sample preparation and laboratory efficiency.
