    Another Nub question, but the sterilization the package is confirming is the outside of the vial? So would the inside already be sterile? And if so would using an alcohol wipe on the outside take care of the sterilization of the outside issue?

      @jacobferguson the bottle and stopper are inside the sealer package. The package is then ran through an autoclave. If processed properly the color change square turns from blue to black. The stopper/plunger does come out during processing due to pressure. When the package is completely dry the stopper is pushed back into the vial through the package. If the item has been properly sterilized in an autoclave it is sterile inside and out.
      As soon as you remove the vial from the sealed package the exterior is exposed to air and becomes unsterile, so you clean to top with alcohol every time you insert a needle into the end, either for filling or for use once filled.

          Im new to this and I was worried after reading through this post. I contacted the vendor I got mine from and this is what he said. What do you guys think?

            Ozone only works on tyvek packages. Steam sterilization packages are cellulose material.

              Looking at the package if the process he claims was used the top pink box would have to be yellow right? I mentioned I was new to this and he probably thinks I would buy his response.

                The pink square is chemical sterilization. Chemclave. Ozone is oxygen (O3)
                I would think ozone would be an expensive way to sterilize batches of cartridges.

                    I’ve gotten vials from a half dozen Amazon vendors to review recently. All the ones with the half circle cut out tab are suspicious to me. The color change area is shiny like ink, like it’s been printed. It doesn’t run with water either. The ones with an elongated cut out tab, and I know area validly processed, the color change areas get lighter if you get it wet.

                      I swear I'm just gonna buy me a used autoclave, buy everything in bulk and start sterilizing the cartridges myself.
