FAQs of 13/20/25/30/32/33mm Bromo/Butyl Rubber Stoppers:

Q: How do I sterilize Bromo/Butyl Rubber Stoppers for pharmaceutical use?

A: These stoppers can be sterilized using autoclaving, gamma irradiation, or ethylene oxide, as they are designed to be fully compatible with these methods without compromising their physical or chemical integrity.

Q: What are the benefits of using Bromo/Butyl Rubber Stoppers in injection vial closures?

A: Their excellent resistance to gases, moisture, and chemicals ensures leak-proof sealing and prevents contamination. The latex-free, odorless nature minimizes patient risk, and the low extractables comply with USP/EP standards, making them ideal for sensitive pharmaceuticals and biotech uses.

Q: When should I replace or not use these stoppers?

A: Replace the stoppers if stored beyond their maximum shelf life of 24 months, or if they show signs of visible damage. Always use stoppers within their recommended storage conditionsin cool, dry, and dust-free environmentsto maintain sterility and performance.

Q: Where can these rubber stoppers be applied in medical and biotech industries?

A: They are suitable for sealing pharmaceutical vials, injection vial closures, medical packaging, and various biotech applications. Their versatility covers serum vials, lyophilization vials, and flip-off styles.

Q: What is the manufacturing process of these stoppers and why does it matter?

A: The stoppers are produced using compression molding, which provides consistent density, shape, and material properties, ensuring uniform sealing and compatibility with a wide range of vial types.

Q: How is the quality of these stoppers ensured before shipment?

A: Each batch is manufactured with precise size tolerance (0.1mm), tested for leak resistance and compliance with chemical content specifications including ash percentage, nitrogen, and volatile matter. Packaging is done in polybags of 500 or 1000 pieces to preserve cleanliness.

Q: What advantages does Bromo/Butyl Rubber offer over natural rubber in vial sealing?

A: Bromo/Butyl Rubber provides superior resistance to chemicals, moisture, and gases compared to natural rubber, with enhanced temperature and flame resistance. It is synthetic and latex-free, reducing allergen risk and ensuring robustness for demanding pharmaceutical environments.
