Ks-Tek Sterile Empty Vials with Self Healing Injection Port,with Aluminum Plastic Cap,Sterile Package (3ml Amber,10)

Every time I use an insulin syringe to draw the liquid from the vial, the needle seems to get damaged or blunted as it passes through the rubber seal. As a result, the needle is no longer sharp and it hurts when I inject. It appears that the rubber seal on the vial may not be suitable for use with insulin syringes

you can't really use them efficiently. I tried using them for material for injection like weight loss medication, but they are not high quality. don't get me wrong, they do the job if you're a doctor like me, but I wouldn't recommend them.

Good!

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.

Ótimo, veio cada um em uma embalagem. Que pena que na achei aqui em João Pessoa. A entrega foi rápida, mesmo vindo de fora. Super recomendo.

These vials are well made and have a quality stopper. The large size means that you can make fewer batches of your serums or lab solutions. The amber bottle also protects light sensitive chemicals.
