The Guanshentai Automatic Centrifuge Tube Capping Machine is a specialized system designed for the automated tightening and loosening of caps on tubular consumables, such as centrifuge tubes, cryovials, and micro-tubes. The equipment integrates automatic tube feeding and orientation, cap feeding and alignment, servo-controlled capping torque, in-line inspection, and automatic discharge. It provides a comprehensive, one-stop automated solution—transforming bulk tubes and caps into finished, capped centrifuge tubes. With a processing speed of 60–120 tubes per minute, it effectively replaces manual capping, ensuring consistent sealing quality and significantly boosting production efficiency.

Key Advantages:
Precise Torque Control: The capping mechanism is driven by a servo motor and equipped with a torque sensor for real-time monitoring. Capping torque can be set via a touchscreen (with an accuracy of ±0.05 N·m), ensuring each cap is tightened to the correct specification for a reliable seal, while preventing issues such as stripped threads, overtightening, or loose caps.
Automated Feeding and Orientation: Tubes are automatically sorted and fed via a vibratory bowl feeder, while caps are oriented and aligned by a dedicated cap-handling mechanism. A precision pick-and-place unit then positions each cap onto the tube opening, ensuring a continuous, stable supply without the need for manual intervention.
Multi-Specification Compatibility: By swapping out feed tracks, capping grippers, and positioning fixtures, the system can accommodate a wide range of centrifuge tube sizes—including 0.2 ml, 0.5 ml, 1.5 ml, 2 ml, 5 ml, 15 ml, and 50 ml—with changeover times of under 20 minutes.
Scratch and Contamination Prevention: Components that come into contact with the tubes or caps are crafted from polished, non-metallic, flexible materials to prevent surface scratches or abrasions during the capping process. Dust covers can be added to critical stations to meet the stringent requirements of cleanroom environments.
Robust Design and Easy Maintenance: The machine features a sturdy frame constructed from SUS304 stainless steel and aluminum alloy profiles, ensuring stable operation, corrosion resistance, and ease of cleaning. The capping heads and grippers utilize a quick-release design, making maintenance and component replacement fast and convenient.
Application Scenarios: This equipment is widely used for the automated capping and sealing of tubular containers, including life science consumables (centrifuge tubes, microcentrifuge tubes, cryovials, and PCR tubes), in vitro diagnostic (IVD) consumables (sample collection tubes and nucleic acid extraction tubes), and medical consumables (vacuum blood collection tubes and urine collection tubes). Featuring precise torque control and highly efficient, stable operation, the Guanshentai automatic centrifuge tube capper helps manufacturers of laboratory and medical consumables automate their capping processes—effectively reducing labor costs while enhancing both sealing consistency and production capacity.
