Sterile saline storage

Users discuss options after opening a 20 ml plastic ampule and using only part of it. Transferring the remainder into a sterile vial with a self-sealing stopper is suggested as practical, provided aseptic technique is followed. One participant notes that sterile water can stay sterile under those conditions based on an interview reference. Others compare it to their experience with similar 10 ml ampules and plan to test the approach on their own batches.

• Plastic twist-and-snap ampules do not reseal once opened.
• Sterile vials with rubber stoppers are viewed as a workable storage method.
• Aseptic technique and common sense are cited as key to maintaining sterility.
• Fridge storage is assumed but limited by the 30-day guideline for opened saline.
• Piercing the ampule with a needle is considered as an alternative to fully opening it.

Whether the remaining saline from a popped plastic ampule will reliably stay sterile long enough to justify saving it.

Nothing here is advice.
