For laboratory, research, or controlled compounding applications requiring sterile 10 mL containment, these vials provide dependable quality control and professional-grade reliability.

Very good quality. No issues. Everything is sterile so it is individually wrapped.

i needed one, bought 3 boxes which has worked out well. as i am studying biology, and botany, im using these for sterile cultures and i never expected to be doing that, but it works.

Good quality for a good value.

I used these to bread down my Wegovy. It worked very well and appeared to be very sterile.

I’ve used 3 sets of 10 and not one issue. For those experiencing leaks! Please do yourself a favor. Make sure you pull at least as much air from the vial as you plan on injecting liquid into it. If you inject without depressurizing the vial, there is a good chance you will cause the seal to be compromised with all the pressure you’re creating and therefore leak.

Great product delivered on time.

Beautifully packaged. Neat and clean. Sealed properly and thoughtful with the labels provided.

Amazing little kit! Great quality and the stickers are a great added bonus that others don’t supply!

Alles bestens funktioniert ohne Probleme. Alles steril verpackt.

Would have been better if lids weren't on

Perfect for what I need. Quality is great. Seal is good. Definitely better than other ones I bought where the vacuum doesn't exist and the seal doesn't actually heal properly. Would buy again. Just wish it were cheaper and came with a case to hold vials.
