Round Head Closed Glass Ampoules
Round head closed glass ampoules are professional-grade packaging containers designed specifically for high sealing performance and content safety. The round head closed design at the top not only ensures complete sealing of the bottle but also reduces the risk of mechanical damage during transportation and storage, thereby enhancing overall protective performance. They are suitable for high-demand applications such as sterile liquid medications, skincare essences, fragrance concentrates, and high-purity chemical reagents. Whether used in automated filling lines or for small-batch packaging in laboratories, round-headed closed glass ampoules provide a stable, safe, and aesthetically pleasing packaging solution.

Round head closed glass ampoules are containers commonly used for the sealed packaging of pharmaceutical preparations, chemical reagents, and high-value liquid products. The bottle mouth is designed with a round head closure, which completely isolates the contents from air and contaminants before leaving the factory, ensuring the purity and stability of the contents. The design and production of the product strictly comply with international pharmaceutical packaging standards. From raw material selection to finished product packaging, the entire process is subject to high standards of control to meet the stringent requirements of the pharmaceutical and laboratory fields.
Round-headed closed glass ampoules are available in various capacity specifications, featuring uniformly thick walls and smooth, rounded bottle openings that facilitate thermal cutting or breaking for opening. Transparent versions allow for visual inspection of the contents, while amber-colored versions effectively block ultraviolet light, making them suitable for light-sensitive liquids.
The production process employs high-precision glass cutting and mold forming techniques. The rounded bottle mouth undergoes fire polishing to achieve a smooth, burr-free surface with excellent sealing performance. The sealing process is conducted in a cleanroom environment to prevent particle and microbial contamination. The entire production line is equipped with an automated inspection system that monitors bottle dimensions, wall thickness, and bottle mouth sealing in real-time to ensure batch consistency. Quality inspection adheres to international standards, including defect inspection, thermal shock testing, pressure resistance, and airtightness testing, ensuring each ampoule maintains integrity and sealing under extreme conditions.
Application scenarios include injectable solutions, vaccines, biopharmaceuticals, chemical reagents, and high-end fragrances—liquid products with extremely high requirements for sterility and sealing performance. The rounded-top sealed design offers enhanced protection during transportation and storage. Packaging follows a uniform packing process, with vials neatly arranged by specification on shock-resistant trays or honeycomb paper trays, and enclosed in multi-layer corrugated cardboard boxes to minimize transportation damage rates. Each box is clearly labeled with specifications and batch numbers for convenient warehouse management and traceability.
In terms of after-sales service, the manufacturer offers usage guidance, technical consultations, quality issue returns/exchanges, and customized services (such as capacity, color, graduations, batch number printing, etc.). Payment settlement methods are flexible, accepting wire transfers (T/T), letters of credit (L/C), or other mutually agreed-upon methods to ensure transaction security and efficiency.
