Grey Rubber Stoppers, Feature : Excellent Finishing

Butyl rubber stopper are a crucial component in pharmaceutical glass vials. They play a vital role in maintaining the integrity, sterility, and safety of the vial's contents.

Rubber stoppers allow easy access to drugs contained in glass medication vials, as they can be readily punctured through with a needle or a cannula.

Material:

·       Material Composition: Butyl rubber stoppers are typically made from synthetic butyl rubber, a copolymer of isobutylene and isoprene. This material is known for its excellent sealing properties, low gas permeability, and resistance to moisture.

Key Characteristics:

·       Sterility: Butyl rubber stoppers are designed to maintain the sterility of the contents within the vial. They create an airtight seal, preventing the entry of contaminants and ensuring product safety.

·       Low Extractables: These stoppers have low levels of extractable compounds, which means they release minimal substances that could potentially interact with the pharmaceutical product.

·       Chemical Resistance: Butyl rubber is highly resistant to various chemicals, making it suitable for a wide range of pharmaceutical formulations.

·       Gas Barrier Properties: Butyl rubber provides an effective barrier against gases, such as oxygen and moisture, preventing degradation of the product inside the vial.

Manufacturing and Quality Control:

·       Butyl rubber stoppers are produced under strict quality control conditions to meet pharmaceutical standards. They undergo testing to ensure sterility, consistency, and quality.

Variety:

·       Butyl rubber stoppers come in various sizes and types to accommodate different vial specifications. They can be used for sealing vials of various capacities and designs.

Compatibility:

·       Butyl rubber stoppers are compatible with various drug formulations, including vaccines, injectable medications, and biopharmaceuticals.

Sealing Process:

·       During the vial-filling process, butyl rubber stoppers are typically crimped or inserted into the vial's neck using specialized capping machines. This process ensures a secure and tamper-evident seal.

Usage Precautions:

It's essential to handle butyl rubber stoppers in a clean and controlled environment to maintain their sterility and quality.
