United Scientific 33309 Polypropylene Wide Mouth Reagent Bottles, 500ml Capacity (Pack of 12)

Great bottles. They do not have any plastic smell, and they hold water without leaking.

Great quality. Good for make soapmaking.

Holy Wow Super AwesomeThese are just gosh-darn-great bottles. They are the size and shape of Nalgene's but feel heavier and a lot more solid. They feel good in your hand -I can assume these bottles are polypropylene instead of the polycarbonate that the Nalgene's are --they are just, I dunno, "softer" in your hand, not the brittle feel of the polycarb. The lids are great -good feel, good seal, not jammed into place when trying to unscrew them later. I guess the only gripe I could have is that it would be nice to have volume marks ("graduations"?) on the side. Then again, that's probably why God gave me a Sharpie and (not quite) rudimentary math skills.So yeah, these bottles are double-plus-good. If you figure in that they are less that 2 1/2 bucks and like, 1/3 the cost of Nalgene, they are double rainbows, the cat's meow, sliced bread and the corner-piece brownie.I have spoken,May the Force be with you,Sincerely, Topher!'Ting!

How can a reagent bottle be sold without graduation marks? The bottles themselves are nice, clear and seal well, but I'm utterly baffled by the fact they lack graduation marks. Sigh.

It is what you expect. Polypropylene bottles with a screw cap. They feel solid. I stored liquid ammonia in a couple. They have not leaked liquid, or gas (I cannot smell ammonia, even after a few weeks in a closet).Yeah, they are good.
