Ks-Tek Sterile Empty Vial with Separately Butyl Rubber Stopper and Flip Top Closure,Removable,After Filling,Need to Seal by CrimperType 1 Borosilicate Glass Tubing (30ml)

Here is the crimping tool that I got on Amazon and it worked great. https://www.amazon.com/dp/B0DJ6J1B23

I originally got these vials because I needed the self healing injection ports for a different project. But these vials were made with such precision and quality that I do believe even without the self healing ports, I will find another use for them. I may even use them with the ports as they are!

It’s ok I guess

Challenging. I tried putting the medication in the vial but the rubber stopper kept coming up and out. I tried to push it back in numerous times on different vials but could not get it to stay in place.

Work great for shooting medication pen into, to be able to split up dosage. But have to be very careful as the lids don't stay plugged in and you may spill medication.

They are definitely small but they worked for what I needed.

These arrived empty, unsealed and with no label. Just the way I wanted them. They are perfect tiny little jars for keepsakes and pet fur if you are facing a loss.

Good sterile vials. Cap comes not crimped, which is perfect for my use. Sterilization indicator on the outside. Good quality.
