ZHANXUBIO 5 Ml Sterile Empty Vial, Sterile Glass Vials, With Self-Healing Injection Port And Flip Cap, Sterile Pack 10Pcs Per (5Ml,10)

So far I have been very satisfied with these vials. Appear well made and work as advertised.

These are nice for a small size vial. The stopper is good and have had no issues with them. Give them a try!

The case that these come in is GREAT! It is a thick plastic (?) Case that seals up and clicks together, the tubes are self-sealing after you fill them, it comes with labels and stickers to go over the tops, where you've punctured them, to seal it up to keep it sterile. They are gas sterilized, they have the blue dot that will change color if the sterilization is tampered with or messed up at all, or if the sterilization expires. They are not individually sealed, so once you open them, though, that is it. They will no longer be sterilized, but I'm good with that as I know once they get to me, the environment they will be kept in, and they are personal use. The purple lids, once you pop them off, they will no longer go back on the vials, which was a bummer, but now I see why they give you the stickies for the top of them. I suppose that is ok for what I needed them for. But I felt it was an important thing to point out. They cannot be opened to fill, not that I have found anyway, you do have to puncture them to fill them. I think the case they are in is my favorite thing, I was expecting them to be wrapped in a plastic bag or something, or sealed and sterilized in some kind of individual wrapping somehow, so it was a pleasant surprise to get this container to hold them in too. Though, once filled they are in a fridge, if I were to use them all at once, it would be a great thing to have for sure! also it keeps them organized and neat so I love that.

These are great and work as they should. I'm not able to put too many details but the top works as it should and they hold items as they should. None arrived broken and that's a win.

Vials come in a plastic container which keeps them from being exposed to outside organisms which would defeat the purpose of them arriving sterile. Luckily, these are made of glass so you can re-sterilize them in a pressure cooker or boiling water. Each vial holds 5mls of whatever you wish to put inside of them. They contain a rubber resealable injection port which fits in the top of the vial in order to fill or retract product with/from the vial without exposing the rest of the vial to air by opening the top. On top of the port, there are plastic flip lids which can be sealed or just placed on top for extra security. I really like these and find them to be as good as the quality one would find in a spa which contain sterile products. I also like that they are glass and not plastic so that they are more sterile and can be re-sterilized. I plan on using these for laboratory reasons and I have to sterilize the product after it goes IN the vial and I wouldn't be able to do that with plastic because it would melt and, on a side note, plastic is not good for sterile use in general. The price for a ten pack is very decent and I'll be ordering more.
