Description:
These 20mm gray chlorobutyl rubber stoppers are specifically designed for pharmacy vials, providing a secure, airtight seal for sensitive medications and laboratory contents. Engineered for high-performance sealing, they help protect against contamination, moisture, and oxygen exposure—essential for maintaining product stability and sterility.
Made from premium chlorobutyl rubber, these stoppers offer excellent chemical resistance and extremely low gas permeability, making them a preferred choice for pharmaceutical and medical applications. Compatible with standard 20mm vial necks, they are ideal for injectable drugs, compounded medications, and lab samples.
Key Features:
Standard 20mm size for pharmacy and injectable vials
High-quality gray chlorobutyl rubber construction
Superior chemical resistance and low permeability
Supports sterilization (autoclave compatible under standard conditions)
Provides tight, leak-resistant, airtight seal
Suitable for sterile pharmaceutical environments
Autoclave Compatibility:
These chlorobutyl stoppers are generally autoclavable under standard sterilization conditions (121°C / 250°F at 15 psi for 15–30 minutes). They are designed to maintain elasticity and sealing performance during proper sterilization cycles.
Important:
Do not exceed recommended temperature or cycle times
Performance may vary depending on formulation or coatings
Ensure proper drying and handling after sterilization
Always verify compatibility for your specific application
Applications:
Pharmacy vials and injectable medications
Compounding and drug preparation
Laboratory research and sample storage
Medical and biotech facilities
Chemical and sterile solution containment
