Confirm the Tube and Closure
Provide tube samples or drawings showing the diameter, height and opening size. Also confirm whether the closure is a screw cap, press-fit stopper or another custom design.
Laboratory & Small-Dose Packaging
Test Tube Filling & Capping Machines
Automatic systems for filling, cap feeding, capping and optional labeling of laboratory test tubes, reagent tubes and cosmetic sample containers. Machines can be configured for your tube size, cap type, filling volume, liquid characteristics and production capacity.
Machine Selection Guide
How to Choose a Test Tube Filling & Capping Machine
The correct configuration depends on your tube dimensions, filling volume, liquid properties, closure structure and required production capacity. ZONESUN can customize the filling, feeding, capping and labeling stations.
Select the Filling System
Peristaltic pumps support hygienic fluid paths, ceramic pumps provide precise small-dose filling, and magnetic pumps are suitable for many low-viscosity liquids.
Choose the Automation Level
Systems can integrate tube feeding, liquid filling, cap sorting, cap placement, capping and optional labeling. Confirm the required output in tubes per minute before configuration.
