Bottle Septa

Septa for bottles provide an airtight seal for bottles that prevents environmental contaminants but allows for the removal of the bottle’s contents by piercing with sharp needles. Septa bottle caps are generally available for open-top and screw caps and allow for aseptic syringe dispensing, as well as the addition of materials. Loose septa can be used as replacement parts for bottles with unbonded septas, and caps are also available separately. Septas can generally be autoclaved or dry heat sterilized and are available in multiple materials, including PTFE, silicone and red rubber.
