Cryovials Sterile Tubes 2ml Lab Vials with Caps Cryovial for Low Temperature Storage, Case of 2000

I do not recommend these for long term storage. They do not fully seal so the liquid will eventually evaporate. Example: 1.5ml of 70% ethanol evaporated to 1ml within 3 months at room temperature.

Great tubes - great price

I’m excited to try using these in plant propagation, both to hold a small sample of rooting hormone, but also to add water to fresh cuttings. It’s a good size pack, and each vial is about 1.5 ml. (1.5 ml, NOT 1.5 oz, in case anyone is confused about that—these are about 1/3 of a teaspoon).They're about the width of a pen, and maybe a couple inches long.

This CryoVial package is solid. They hold at least 2ml, and the silicon gasket on the top is really nice. I have no doubt they won't leak. They claim to be autoclavable, and they do feel like genuine polypropylene, so no doubt they'll fare well there. At $28 for a bag of 50 vials, it's a pretty good price. They are much cheaper than what you can get from Sigma Aldrich or elsewhere.Overall, they're solid. The markings are consistent and appear to be accurate. I am very happy with this purchase and will likely get more when I run out.
