PP28 Screw Neck Glass Containers with Various Closure Systems

The PP28 screw neck glass container provides a safe and professional solution for the storage, transport and dispensing of liquids across laboratory, cosmetic, pharmaceutical and industrial applications. Available in a range of capacities — from small volumes to larger formats — and multiple closure configurations, it ensures optimal protection and preservation of the contents.

Glass Material and Characteristics

The containers are manufactured from Type III soda-lime glass, offering good chemical resistance and suitable stability for general and technical use.

• Complies with the specifications of the European Pharmacopoeia and USP.
• Available in clear glass and amber glass:
  • Clear: allows full visibility of the contents, ideal for visual inspection and presentation.
  • Amber: provides protection against light and UV radiation, preventing degradation of photosensitive products. The amber colour is integral to the glass and not a surface coating.
• Functional cylindrical design for easy handling, filling and storage.

Compatible Closure Systems

The standard PP28 thread allows the use of various cap configurations depending on the application:

• PP28 plastic caps with inner PE insert: available in white and black, ensuring improved sealing with the container neck.
• PP28 plastic cap with PTFE (Teflon) liner: in white, offering high chemical resistance and suitability for higher-temperature sterilisation processes.
• PP28 plastic caps with EPE liner: available in red, green and blue, providing an effective seal for general applications.
• PP28 aluminium cap with EPE liner: robust solution with a technical, professional finish, suitable for applications requiring higher resistance or a more premium presentation.
• Syringe-access closure system: two-piece system consisting of a PP28 cap (white or black) with tamper-evident band and an independent dispensing insert, designed for controlled liquid withdrawal using a syringe without fully opening the container.

Applications

• Storage of chemical reagents and solutions.
• Essential oils, perfumes and cosmetic formulations.
• Pharmaceutical products and laboratory samples.
• Use in the food industry for compatible liquids.

Recommendations

It is recommended to clean both the container and its components before use to ensure maximum hygiene. Specific characteristics may vary depending on the selected model and closure type. Caps are supplied according to the corresponding reference.
