Ks-Tek 無菌空バイアル 自己修復注入口付き、アルミニウムプラスチックキャップ、滅菌パッケージ(10、1mlアンバー)

I’ve been really happy with these so far. They arrived well packaged and every vial was individually sealed, which I always like to see with sterile items. Nothing looked damaged or contaminated when I checked them. The glass feels thicker than I expected and not cheap or flimsy. The aluminum caps also look like they were crimped properly, and I didn’t run into any leaking issues. The self-healing injection port seems to reseal well after use too. Overall, they seem well made and reliable. For the price this felt like a solid purchase, and I’d order them again if I need more.

I have a medication that I’m supposed to keep frozen until use…but comes in a 5 ml bottle. The medication kept going bad because I was repeatedly rethawing it. With these little bottles, I’m able to separate the prescription into more manageable doses. I dinged it a star because the rubber seal is much firmer than it needs to be. My 30g needles struggle to make it through without bending.

These vials were easy to use and packaged very well. Good for use of administering medicine at home if needed. I would definitely purchase again.

Injecting original serum into vials went fine but subsequent efforts to withdraw from syringe resulted in original puncture venting air into serum. In other words, the butyl rubber stopper has no self healing or flexible traits allowing original puncture to close. Original puncture gauge was extremely thin. Don’t waste your money!
