United Scientific 33306 Polypropylene Wide Mouth Reagent Bottles, 60ml Capacity (Pack of 12)

The United Scientific® Unistore™ sample containers with lids are light in weight, clean, and leakproof!

Good quality. Good value. Really useful for minimizing volume and weight when traveling. I like them.

There's not much to say, really, except that I wish I could've bought one or two instead of twelve. Still, it doesn't bother me too much except for not knowing what to do with the rest. I work with polymer clay. You always want easy access to water, alcohol, and acetone. I've had the first two in tiny spray bottles but have wanted a small plastic bottle I could put my acetone in instead of having a big clunky bottle that doesn't fit easily in my workspace or some heavy (and fragile) glass jar. It was very difficult to find acetone-compatible plastic, but find it I did. They're tiny bottles, but that's what I needed.

I was tired of buying travel bottles that wound up leaking in my suitcase, so gave these a try. Filled one up with water and laid it on its side for a couple days --- not a drop leaked out. Have used these for a couple trips and so far have been happy with them.

I needed something small to hold acetone conveniently at my project table (for use with a syringe to glue 3D-printed PLA parts together), since acetone comes in giant unwieldy metal containers from the hardware store. I thought glass would be best, but the glass jar I tried had a plastic lid that let all the acetone evaporate out of it in short order. After a bit of googling about plastic types, I bought this little Polypropylene bottle. Well, I bought a dozen of them since there was no 1-pack available. But anyway, this bottle has been holding acetone for 3 months now and the level hasn't noticeably dropped. Great success!
