Clear Glass Vials with Screwcap Empty Vials Bottles Liquid Sampling Sample Glass Bottles for Travel (50 pcs 10 Ml)

These are great sample bottles for my business. Just what I needed and will be ordering again.

I’ve been using these to experiment with fragrance blends for my brand. They are the perfect size for that. The vial itself sturdy, and the cap screws on tightly. I usually shake/swirl my blends a bit, and haven’t had any problems with leakage. I would buy these again.

Just the right size for the antique point contact transistors, grown junction transistors, tetrode grown junction transistors, surface barrier transistors, etc. that I have. However the neck is too narrow for the " top hat" case style.

I use these for oils, serums, and masks and they never ever spill. The size is a little bigger than I thought but they’re still perfect. I love that they don’t leak!

Glass sample bottles were excellent. The caps were a ABS-style plastic and not a rigid phenolic, and they have a very strange screw thread which means caps can't be interchanged with other lab sample bottles. But they do their job, and are surprisingly rugged for something so small made out of glass. Caps may make them inappropriate for very long-term storage though.

Perfect size for what was neededScrew cap holds liquid from leakingUsed this product to condense liquid from 16 oz bottles to smaller sizes for distribution

I use these for insects and essential oils. Nice tight and secure seal

Sometimes the tops loosen and a little liquid drips out. It happens to very few of them. Otherwise it is a superior product.
