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

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’ve reconstituted various peptides for some time now and these are great vials, never had a leak, I’ve even dropped one on my tile floor and it just bounced, so they’re pretty darn tough too. Good value, and perfect size for 10,000 IU peptides.

Easy to use, perfect size and very durable material. Definitely recommend this product

I use these to filter peptides into. They seem to be sterile, but have no way of really testing them without spending hundreds of dollars. I know numerous people who use them without issue, so they seem to be fine.

A bit hard to removed the blue cap but otherwise great. Individually wrapped for sterility. Good product.

Good seal, glass is clear and strong with no defects.

I use these to empty my injection medication into and divide it into thirds (used with a syringe) and these work great. They are a great quality and seal perfectly.

I use these for my GLP1 injections, I inject into the vial, add some bacteriostatic water and then voila, divide it into three injections. All of the vials arrived overseas unbroken and ready to use. Each vial was individually wrapped. No leakage. The only complaint I have is that there is no re-usable lid for storage. Minor thing, but work without.

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.

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.
