What is a Lab Test Tube Filling and Capping Machine?

fully electric liquid filling machine

In industries where precision is non-negotiable—such as pharmaceuticals, diagnostics, cosmetics, and scientific research—automated lab packaging solutions must deliver reliability, repeatability, and flexibility. The ZONESUN ZS-KXG620 Lab Test Tube Filling and Capping Machine is purpose-built for such high-demand environments. With its fully electric, servo-driven system, this advanced monoblock machine ensures ultra-precise liquid filling and cap application, making it ideal for test tubes, vials, and other small-format containers.

Full-Electric & Servo-Controlled for Unmatched Precision

Unlike traditional pneumatic or semi-automatic solutions, the ZS-KXG620 is entirely electric. Every critical motion—from bottle positioning to liquid dispensing and cap tightening—is driven by high-performance servo motors, delivering extremely stable and repeatable performance. This translates to highly accurate fill volumes, consistent torque control for capping, and minimal risk of contamination or leakage.

Ideal for Laboratories and High-Accuracy Applications

Whether you're filling test tubes for medical analysis, R&D sampling, or small-batch cosmetic products, precision is paramount. The ZS-KXG620 is engineered to handle:

  • Micro-dosing requirements

  • Small-volume liquid packaging

  • Test tube and vial capping

  • Products with tight tolerance requirements

Its advanced filling system ensures that even the smallest volumes are dispensed with exceptional accuracy—significantly reducing product waste and batch rejection rates.
