5ml Clear Glass Vials-1-1/2 Dram Clear Glass Headspace Vials with Plastic-Aluminum Flip Caps and Rubber Injection Stoppers, 100 Pack, 20mm Flat Bottom Lab Vial

I work in medical simulation and these vials are awesome for training new medical staff. Using powder sugar for quick desolvable contents or adding sugar crystals or salt to show sediment for reconstitution of medication. Also the psychomotor skill of removing caps and using aseptic technique when withdrawing liquid and accurately measuring medications has been great with these products.

I can't exactly say why, but I have always had an appreciation for small glass bottles. These are the perfect size to store random things in. The lid consists of two parts, a silicone lid and a metal and plastic lid that goes on top of the silicone lid. A special tool is required to crimp the metal lid down on top of the silicone lid but you only need to buy this tool once and it will last a lifetime. It is great for storing everything you could imagine! You can store medicine, liquids, seeds, whatever your heart desires! Just throw it in these bottles put a lid on it and if you want to seal it up airtight, get one of the tools that crimps the metal down to make a nice permanent seal. If you sell a bottle and want to open it, it is easy to rip the metal and remove the cap. At the same time it is very sturdy so you don't have to worry about anything falling out of it. If you like glass bottles and storing random things and then this is an awesome investment for you. Like I said, I really enjoy these bottles so much, this is the second time I have bought them. Excellent airtight seal and outstanding performance!

Excellent. As advertised.

look, they seal fine, butYOU SHOULD KNOW...the lids have cut outs that makes you rip the whole thing off. I had to rebuy different ones. See picture, when you rip off plastic part, it's cut so that it takes the whole aluminum part off. Maybe it's for some other reason but for my uses it becomes unsanitary to use.

Always get what I ordered, quick delivery.

I stock peptides in my studio and these are fantastic to repackage them into smaller quantities. Glass is solid and the lids crimp and seal perfectly every time. Will definitely purchase again!
