The Guanshentai Automatic Centrifuge Tube Capping Machine is specialized equipment designed for the precise, automated screwing of caps onto threaded tubes—such as centrifuge tubes, cryovials, and sampling tubes. Integrating automatic feeding and sorting of tubes and caps, precision capping, torque monitoring, and automatic unloading, the system utilizes servo-driven technology and high-precision torque control to ensure accurate threading. It achieves capping speeds of 30–60 tubes per minute with a torque control precision of ±0.05 N·m, effectively replacing manual capping operations.

Key Advantages:
Precision Torque Control: The capping mechanism is driven by a servo motor and utilizes a high-precision torque sensor for real-time feedback. Torque values are user-defined and automatically controlled, ensuring consistent tightness and reliable sealing for every tube while eliminating issues such as stripped threads, overtightening, or poor seals.
Automatic Feeding and Sorting: Tubes are sorted and fed via a vibratory bowl or stepped elevator, while caps are arranged by a dedicated sorting mechanism and conveyed to the capping station. Continuous, stable supply of components eliminates the need for manual placement.
Capping Verification and Error Prevention: Equipped with photoelectric sensors to detect proper cap seating and a torque curve monitoring system, the machine performs a dual check on capping angle and torque. It automatically alarms and halts operation if capping is incomplete or torque is abnormal, preventing the release of defective products.
Flexible, Damage-Free Clamping: The tube clamping and positioning mechanism features non-metallic, flexible contact surfaces (silicone or polyurethane). Adjustable clamping force ensures the tube remains stable and stationary during capping while preventing damage or deformation to the tube walls.
Multi-Specification Compatibility: By simply swapping track molds and capping chucks, the machine quickly adapts to various centrifuge tube sizes—including 0.2ml, 0.5ml, 1.5ml, 2ml, 5ml, 15ml, and 50ml—covering tube diameters from 10mm to 30mm, ensuring convenient and efficient product changeovers.
Clean-room Compatible Design: The machine features an SUS304 stainless steel frame, and all product-contact parts comply with clean production standards. It is suitable for operation in Class 100,000 cleanrooms, meeting the environmental requirements for the manufacture of medical devices and biological consumables.
User-Friendly Operation: Equipped with a PLC and touchscreen HMI, the system allows for intuitive setting of parameters such as capping speed and torque values. It stores multiple product recipes that can be recalled and switched with a single touch during changeovers, enabling general operators to run the machine after minimal training.
Applications:
Ideally suited for precision screw-capping operations involving threaded tubes and caps in sectors such as life science consumables (centrifuge tubes, cryovials, sampling tubes, preservation tubes), in vitro diagnostic (IVD) consumables (sample preservation tubes, nucleic acid extraction tubes), and biopharmaceuticals (reagent dispensing tubes, culture media tubes). With its precise, stable, and clean capping performance, the Guanshentai automatic centrifuge tube capping machine helps manufacturers of laboratory and medical consumables automate their tube-capping processes while ensuring reliable sealing integrity.
