How to Choose the Best Lab Cap Plugs
Sterilization and Compatibility
Ensure the cap plugs are compatible with your sterilization methods, whether it's autoclaving, dry heat, or chemical sterilization. Some materials can degrade or deform under high temperatures or with prolonged exposure to certain sterilizing agents. Check the manufacturer's specifications for recommended sterilization procedures and any material compatibility notes to avoid compromising the plug's integrity or your lab's sterility.
