Automated Glass Test Tube Filling: Boosting Efficiency in Labs and Pharmaceutical Production

In modern pharmaceutical, cosmetic, and laboratory industries, glass test tubes are a common container, and their accurate, efficient filling process is critical. Traditional manual filling is not only time-consuming but also prone to cross-contamination, affecting product quality. To solve these issues, the ZONESUN ZS-FAL180V6 Automatic Glass Test Tube Filling Monoblock Equipment was developed.
Integrated Design: Advantages of Monoblock Production

The ZS-FAL180V6 features an advanced monoblock design that integrates multiple processes—tube positioning, liquid filling, capping, torque adjustment, and labeling—into a single machine. Key highlights include:
-
High-precision filling: Uses a peristaltic pump to ensure liquid flows only through tubes, avoiding contamination; suitable for 10–30ml volumes.
-
Reliable capping: Equipped with a servo motor-driven capping system for secure sealing.
-
Intelligent labeling: Built-in photo-eye detection system for precise label placement.
-
High efficiency: Can process approximately 20 test tubes per minute, significantly increasing productivity.

Applications: From Laboratory to Industrial Production
The ZS-FAL180V6 is ideal for various industries, particularly:
-
Pharmaceuticals: Filling and sealing vaccines, reagents, and injectable products.
-
Cosmetics: Suitable for small-volume items like serums and perfumes.
-
Laboratories: Provides accurate liquid dispensing solutions for research and testing.
