Replacement Septa


SKU: N/A Category:


This is the replacement septa only. Does not include the screw cap lid.

To replace a septum, push the old septum out of the cap and discard.

  1. Insert the new septum with the white side facing the cap’s hole. Be sure to seat the septum as evenly as possible using a pencil eraser or something similar.
  2. To ensure proper seating, tighten the cap onto a vial, loosen, and tighten again. Remove and inspect the cap to be sure the septum is evenly seated all the way.
