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.

Sep 28, 2015 · The septa are formed from 2 layers. The PTFE is on the lower side that faces your sample in the vial and is relatively inert to solvents. The top side is red coloured rubber or a silicone that helps to make the seal with the cap on crimping. In general the Rubber/PTFE septum is fine for general use for 1 or 2 injections within a short space of
