Funnel-Neck Glass Ampoules
Funnel-neck glass ampoules feature a funnel-shaped neck structure, significantly improving the efficiency of liquid or powder filling while minimizing spills and waste during the filling process. The ampoules have uniform wall thickness and high transparency, and are sealed in a dust-free environment to ensure compliance with pharmaceutical-grade or laboratory-grade quality standards. The ampoule bodies are formed using high-precision molds and undergo rigorous flame polishing, resulting in smooth, burr-free necks that facilitate heat sealing or breaking for opening. The funnel-shaped neck not only improves filling efficiency but also provides a smoother liquid dispensing experience when opening, making it suitable for automated production lines and laboratory operations.

Funnel-neck glass ampoules are a type of sealed packaging container widely used in the pharmaceutical, chemical, and laboratory fields. The product undergoes precise design and strict control at every stage, from raw material selection to final packaging, with each step reflecting professional quality and safety assurance.
Funnel-neck glass ampoules are available in various sizes and capacities. The inner diameter of the bottle opening and the proportion of the bottle body are precisely calculated to accommodate both automated filling lines and manual operations. The high transparency of the bottle body facilitates visual inspection of liquid color and purity. Brown or other colored options can also be provided upon request to prevent UV light exposure.
The production material is high borosilicate glass, which has a low thermal expansion coefficient and excellent high-temperature and chemical corrosion resistance, capable of withstanding high-pressure steam sterilization and corrosion by various solvents. The glass material is non-toxic and odorless, and complies with international pharmaceutical glass standards.
During production, the glass tubing undergoes cutting, heating, mold forming, and flame polishing. The bottle neck features a smooth, rounded funnel-shaped transition, facilitating smooth liquid flow and ease of sealing. The junction between the bottle neck and body is reinforced to enhance structural stability.
