perfect, quick delivery

Great for making up stock aqueous solutions

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.

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!

Just what was needed. Inexpensive and arrived quickly.

These were much cheaper than the Nalgene bottles off Fisher Scientific. They work just fine for our purposes (carrying sterilants to the field).

I bought them to mix liquid dye. Perfect for the job

Nice bottles - seal well - individually wrapped - exactly as expected from a polypropylene bottle.

work as desctibed feels like i underpaid

These are good sturdy bottles!
