Deep Dive & FAQ
Mastering Precision in Injectable Liquid Filling
In the world of sterile injectables, the margin for error is zero. Our injectable liquid filling machine focuses on the "Three No's": No Bubbles, No Scratches, and No Contamination. By integrating advanced servo motors and vacuum technology, we ensure that the physical properties of the liquid remain unchanged from the tank to the syringe.
Q: How do you handle high-viscosity injectable liquids?
A: Our machines utilize specialized vacuum-assisted stoppering and slow-draw ceramic pumps to prevent cavitation and ensure bubble-free results for thick gels.
Q: Is the machine compatible with different syringe brands?
A: Yes, the modular design of our injectable liquid filling machine allows for quick format changes between various brands of nests and tubs.
