Serum bottle stoppers are essential components used in pharmaceutical packaging to seal vials and bottles containing liquid medications, particularly injectable solutions. Made primarily from rubber or elastomeric materials, these stoppers provide a secure barrier to prevent contamination and maintain the integrity of the product. They are designed to be punctured by needles for easy access to the medication inside while ensuring a tight seal when not in use.
