We use these in place of buying from the manufacturer and they’re identical. It’s so much cheaper and works great for a GC application.

Excellent for what I've needed in the laboratory. Cap fits well. I place Kapton tape along the underside of the cap, in order to make it more resistant to volatile or corrosive solutions. These are well made and the caps hold on well, no issues to report whatsoever.

Work for what they were intended for. The printing on the outside of the vials came off when they were cleaned in an ultrasound bath but that wasn't a problem for my use.

Might not be the intended use but indeed they are fantastic for DIY perfumers who experiment with different aromachemicals!

The volume markings are accurate and they do have a perfect seal.

Good value for the price. Didn’t work for our needs, and the return was seamless.
