2ml Autosampler Vial, 1000 Pack HPLC/GC Vials 9-425 Lab Amber Vials Sample Vial Screw Cap Writing Patch Red PTFE & White Silicone Septa for LC Stamper

I needed these so that I can make essential oil blends and use them while I'm traveling. I have a travel diffuser and I can't bring a bunch of larger bottles with me. With these, I can fill them up with different oils and take multiple blends to enhance my mood or freshen up my hotel. I'm super pleased with these. They are very good quality. These will last me a very long time. I am so grateful for these and they meet my niece perfectly.

I have an essential oil distillation apparatus (among other chemistry lab wonders) and this spring and summer I intend to try extracting essential oils from everything around, from Tulips to Lilacs. I won't have a large volume of each substance, but I should have a large number of samples of whatever I try in the distiller. So this 1000 count box of 2ml vials is actually perfect for a large number of small essential oil samples. Having a spot to write on should make them easier to remember which is which. And hopefully the amber glass will help prevent breakdown. They all came VERY well packaged, and I'm quite pleased with the vials. 5 stars.
